According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A flaw was found in the     Linux kernel's implementation of the invert video code     on VGA consoles when a local attacker attempts to     resize the console, calling an ioctl VT_RESIZE, which     causes an out-of-bounds write to occur. This flaw     allows a local user with access to the VGA console to     crash the system, potentially escalating their     privileges on the system. The highest threat from this     vulnerability is to data confidentiality and integrity     as well as system availability.(CVE-2020-14331)A flaw     was found in the HDLC_PPP module of the Linux kernel in     versions before 5.9-rc7. Memory corruption and a read     overflow is caused by improper input validation in the     ppp_cp_parse_cr function which can cause the system to     crash or cause a denial of service. The highest threat     from this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-25643)A memory out-of-bounds     read flaw was found in the Linux kernel before 5.9-rc2     with the ext3/ext4 file system, in the way it accesses     a directory with broken indexing. This flaw allows a     local user to crash the system if the directory exists.
    The highest threat from this vulnerability is to system     availability.(CVE-2020-14314)A TOCTOU mismatch in the     NFS client code in the Linux kernel before 5.8.3 could     be used by local attackers to corrupt memory or     possibly have unspecified other impact because a size     check is in fs/ nfs/ nfs4proc.c instead of fs/ nfs/     nfs4xdr.c, aka CID-b4487b935452.(CVE-2020-25212)The rbd     block device driver in drivers/block/rbd.c in the Linux     kernel through 5.8.9 used incomplete permission     checking for access to rbd devices, which could be     leveraged by local attackers to map or unmap rbd block     devices, aka CID-f44d04e696fe.(CVE-2020-25284)A race     condition between hugetlb sysctl handlers in     mm/hugetlb.c in the Linux kernel before 5.8.8 could be     used by local attackers to corrupt memory, cause a NULL     pointer dereference, or possibly have unspecified other     impact, aka CID-17743798d812.(CVE-2020-25285)A flaw was     found in the Linux kernel before 5.9-rc4. Memory     corruption can be exploited to gain root privileges     from unprivileged processes. The highest threat from     this vulnerability is to data confidentiality and     integrity.(CVE-2020-14386)In the Linux kernel through     5.8.7, local attackers able to inject conntrack netlink     configuration could overflow a local buffer, causing     crashes or triggering use of incorrect protocol numbers     in ctnetlink_parse_tuple_filter in net/ netfilter/     nf_conntrack_netlink.c, aka     CID-1cc5ef91d2ff.(CVE-2020-25211)The VFIO PCI driver in     the Linux kernel through 5.6.13 mishandles attempts to     access disabled memory space.(CVE-2020-12888)The kernel     in Red Hat Enterprise Linux 7 and MRG-2 does not clear     garbage data for SG_IO buffer, which may leaking     sensitive information to userspace.(CVE-2014-8181)A     flaw was found in the Linux kernels SELinux LSM hook     implementation before version 5.7, where it incorrectly     assumed that an skb would only contain a single netlink     message. The hook would incorrectly only validate the     first netlink message in the skb and allow or deny the     rest of the messages within the skb with the granted     permission without further     processing.(CVE-2020-10751)The Linux kernel through     5.7.11 allows remote attackers to make observations     that help to obtain sensitive information about the     internal state of the network RNG, aka     CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)A buffer over-read     flaw was found in RH kernel versions before 5.0 in     crypto_authenc_extractkeys in crypto/authenc.c in the     IPsec Cryptographic algorithm's module, authenc. When a     payload longer than 4 bytes, and is not following     4-byte alignment boundary guidelines, it causes a     buffer over-read threat, leading to a system crash.
    This flaw allows a local attacker with user privileges     to cause a denial of service.(CVE-2020-10769)In the     Linux kernel through 5.7.6, usbtest_disconnect in     drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)An issue was     discovered in the Linux kernel through 5.7.1.
    drivers/tty/vt/keyboard.c has an integer overflow if     k_ascii is called several times in a row, aka     CID-b86dab054059.(CVE-2020-13974)go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)An issue was     discovered in the Linux kernel before 5.0.6. In     rx_queue_add_kobject() and netdev_queue_add_kobject()     in net/core/ net-sysfs.c, a reference count is     mishandled, aka CID-a3e23f719f5c.(CVE-2019-20811)An     issue was discovered in the Linux kernel before 5.4.7.
    The prb_calc_retire_blk_tmo() function in     net/packet/af_packet.c can result in a denial of     service (CPU consumption and soft lockup) in a certain     failure case involving TPACKET_V3, aka     CID-b43d1f9f7067.(CVE-2019-20812)A flaw was found in     the Linux kernel's implementation of Userspace core     dumps. This flaw allows an attacker with a local     account to crash a trivial program and exfiltrate     private kernel data.(CVE-2020-10732)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In calc_vm_may_flags of ashmem.c, there is a possible     arbitrary write to shared memory due to a permissions     bypass. This could lead to local escalation of     privilege by corrupting memory shared between     processes, with no additional execution privileges     needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel     Android ID: A-142938932(CVE-2020-0009)

  - A flaw was found in the Linux kernel's implementation     of Userspace core dumps. This flaw allows an attacker     with a local account to crash a trivial program and     exfiltrate private kernel data.(CVE-2020-10732)

  - An issue was discovered in the Linux kernel before     5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a     reference count is mishandled, aka     CID-a3e23f719f5c.(CVE-2019-20811)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - A flaw was found in the Linux kernels SELinux LSM hook     implementation before version 5.7, where it incorrectly     assumed that an skb would only contain a single netlink     message. The hook would incorrectly only validate the     first netlink message in the skb and allow or deny the     rest of the messages within the skb with the granted     permission without further processing.(CVE-2020-10751)

  - A signal access-control issue was discovered in the     Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32     bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process     can send an arbitrary signal to a parent process in a     different security domain. Exploitation limitations     include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where     signals to a parent process present a substantial     operational threat.(CVE-2020-12826)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem in versions before 5.7. This     flaw occurs while importing the Commercial IP Security     Option (CIPSO) protocol's category bitmap into the     SELinux extensible bitmap via the'     ebitmap_netlbl_import' routine. While processing the     CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of     service.(CVE-2020-10711)

  - gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)

  - An issue was discovered in the Linux kernel through     5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka     CID-83c6f2390040.(CVE-2020-12770)

  - __btrfs_free_extent in fs/btrfs/extent-tree.c in the     Linux kernel through 5.3.12 calls btrfs_print_leaf in a     certain ENOENT case, which allows local users to obtain     potentially sensitive information about register values     via the dmesg program. NOTE: The BTRFS development team     disputes this issues as not being a vulnerability     because '1) The kernel provide facilities to restrict     access to dmesg - dmesg_restrict=1 sysctl option. So     it's really up to the system administrator to judge     whether dmesg access shall be disallowed or not. 2)     WARN/WARN_ON are widely used macros in the linux     kernel. If this CVE is considered valid this would mean     there are literally thousands CVE lurking in the kernel
    - something which clearly is not the     case.'(CVE-2019-19039)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of kernel installed on the remote host is prior to 4.14.186-146.268. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1465 advisory.

    An issue where a provided address with access_ok() is not checked was discovered in     i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through     4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory,     resulting in a Denial of Service or privilege escalation. (CVE-2018-20669)

    A flaw was found in the prctl() function, where it can be used to enable indirect branch speculation after     it has been disabled. This call incorrectly reports it as being 'force disabled' when it is not and opens     the system to Spectre v2 attacks. The highest threat from this vulnerability is to confidentiality.
    (CVE-2020-10768)

    relay_open in kernel/relay.c in the Linux kernel through 5.4.1 allows local users to cause a denial of     service (such as relay blockage) by triggering a NULL alloc_percpu result. (CVE-2019-19462)

    A logic bug flaw was found in the Linux kernel's implementation of SSBD. A bug in the logic handling     allows an attacker with a local account to disable SSBD protection during a context switch when additional     speculative execution mitigations are in place. This issue was introduced when the per task/process     conditional STIPB switching was added on top of the existing SSBD switching. The highest threat from this     vulnerability is to confidentiality. (CVE-2020-10766)

    A flaw was found in the Linux kernel's implementation of the Enhanced IBPB (Indirect Branch Prediction     Barrier). The IBPB mitigation will be disabled when STIBP is not available or when the Enhanced Indirect     Branch Restricted Speculation (IBRS) is available. This flaw allows a local attacker to perform a Spectre     V2 style attack when this configuration is active. The highest threat from this vulnerability is to     confidentiality. ( CVE-2020-10767)

    An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation fails. (CVE-2020-12771)

    A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

    A flaw was found in the Linux Kernel in versions after 4.5-rc1 in the way mremap handled DAX Huge Pages.
    This flaw allows a local attacker with access to a DAX enabled storage to escalate their privileges on the     system. (CVE-2020-10757)

Tenable has extracted the preceding description block directly from the tested product security advisory.

  - In the Android kernel in i2c driver there is a possible out of bounds write due to memory corruption. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9454)

  - In the Android kernel in the video driver there is a use after free due to a race condition. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9458)

  - There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of     ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device     file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed,     it can cause an exploitable condition as the process wakes up to terminate and clean all attached files.
    The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the     inode. (CVE-2020-10690)

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

  - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS     client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause     a kernel panic. The highest threat from this vulnerability is to data confidentiality and system     availability. (CVE-2020-10742)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
    (CVE-2020-10942)

  - An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-     based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-     aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the     issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering     the bug does not grant any powers not already held. (CVE-2020-11565)

  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in     a different security domain. Exploitation limitations include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where signals to a parent process present a substantial     operational threat. (CVE-2020-12826)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN     and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't     correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would     allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this     vulnerability is to data confidentiality. (CVE-2020-1749)

  - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest     when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in     drivers/tty/vt/vt.c. (CVE-2020-8647)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region     function in drivers/video/console/vgacon.c. (CVE-2020-8649)

  - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to     a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it,     aka CID-2e90ca68b0d2. (CVE-2020-9383)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc. Security Fix(es):In the Android kernel in     F2FS driver there is a possible out of bounds read due     to a missing bounds check. This could lead to local     information disclosure with system execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9445)In calc_vm_may_flags of     ashmem.c, there is a possible arbitrary write to shared     memory due to a permissions bypass. This could lead to     local escalation of privilege by corrupting memory     shared between processes, with no additional execution     privileges needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel     Android ID: A-142938932(CVE-2020-0009)A new domain     bypass transient execution attack known as Special     Register Buffer Data Sampling (SRBDS) has been found.
    This flaw allows data values from special internal     registers to be leaked by an attacker able to execute     code on any core of the CPU. An unprivileged, local     attacker can use this flaw to infer values returned by     affected instructions known to be commonly used during     cryptographic operations that rely on uniqueness,     secrecy, or both.(CVE-2020-0543)A flaw was found in the     Linux kernel's implementation of the BTRFS file system.
    A local attacker, with the ability to mount a file     system, can create a use-after-free memory fault after     the file system has been unmounted. This may lead to     memory corruption or privilege     escalation.(CVE-2019-19377)A NULL pointer dereference     flaw may occur in the Linux kernel's relay_open in     kernel/relay.c. if the alloc_percpu() function is not     validated in time of failure and used as a valid     address for access. An attacker could use this flaw to     cause a denial of service.(CVE-2019-19462)A NULL     pointer dereference flaw was found in     tw5864_handle_frame function in     drivers/media/pci/tw5864/tw5864-video.c in the TW5864     Series Video media driver. The pointer 'vb' is     assigned, but not validated before its use, and can     lead to a denial of service. This flaw allows a local     attacker with special user or root privileges to crash     the system or leak internal kernel     information.(CVE-2019-20806)go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)An issue was     discovered in the Linux kernel before 5.0.6. In     rx_queue_add_kobject() and netdev_queue_add_kobject()     in net/coreet-sysfs.c, a reference count is mishandled,     aka CID-a3e23f719f5c.(CVE-2019-20811)A flaw was found     in the way the af_packet functionality in the Linux     kernel handled the retirement timer setting for     TPACKET_v3 when getting settings from the underlying     network device errors out. This flaw allows a local     user who can open the af_packet domain socket and who     can hit the error path, to use this vulnerability to     starve the system.(CVE-2019-20812)A NULL pointer     dereference flaw was found in the Linux kernel's     SELinux subsystem. This flaw occurs while importing the     Commercial IP Security Option (CIPSO) protocol's     category bitmap into the SELinux extensible bitmap via     the' ebitmap_netlbl_import' routine. While processing     the CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of     service.(CVE-2020-10711)A flaw was found in the Linux     kernel's SELinux LSM hook implementation, where it     anticipated the skb would only contain a single Netlink     message. The hook incorrectly validated the first     Netlink message in the skb only, to allow or deny the     rest of the messages within the skb with the granted     permissions and without further processing. At this     time, there is no known ability for an attacker to     abuse this flaw.(CVE-2020-10751)A flaw was found in the     Linux Kernel in versions after 4.5-rc1 in the way     mremap handled DAX Huge Pages. This flaw allows a local     attacker with access to a DAX enabled storage to     escalate their privileges on the     system.(CVE-2020-10757)A logic bug flaw was found in     the Linux kernel's implementation of SSBD. A bug in the     logic handling allows an attacker with a local account     to disable SSBD protection during a context switch when     additional speculative execution mitigations are in     place. This issue was introduced when the per     task/process conditional STIPB switching was added on     top of the existing SSBD switching. The highest threat     from this vulnerability is to     confidentiality.(CVE-2020-10766)A flaw was found in the     Linux kernel's implementation of the Enhanced IBPB     (Indirect Branch Prediction Barrier). The IBPB     mitigation will be disabled when STIBP is not available     or when the Enhanced Indirect Branch Restricted     Speculation (IBRS) is available. This flaw allows a     local attacker to perform a Spectre V2 style attack     when this configuration is active. The highest threat     from this vulnerability is to     confidentiality.(CVE-2020-10767)A flaw was found in the     prctl() function, where it can be used to enable     indirect branch speculation after it has been disabled.
    This call incorrectly reports it as being 'force     disabled' when it is not and opens the system to     Spectre v2 attacks. The highest threat from this     vulnerability is to confidentiality.(CVE-2020-10768)A     flaw was found in the ZRAM kernel module, where a user     with a local account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)A stack buffer overflow     issue was found in the get_raw_socket() routine of the     Host kernel accelerator for virtio net (vhost-net)     driver. It could occur while doing an     ictol(VHOST_NET_SET_BACKEND) call, and retrieving     socket name in a kernel stack variable via     get_raw_socket(). A user able to perform ioctl(2) calls     on the '/dev/vhost-net' device may use this flaw to     crash the kernel resulting in DoS     issue.(CVE-2020-10942)A flaw was found in the Linux     kernel's implementation of the pivot_root syscall. This     flaw allows a local privileged user (root outside or     root inside a privileged container) to exploit a race     condition to manipulate the reference count of the root     filesystem. To be able to abuse this flaw, the process     or user calling pivot_root must have advanced     permissions. The highest threat from this vulnerability     is to system availability.(CVE-2020-12114)A     use-after-free flaw was found in usb_sg_cancel in     drivers/usb/core/message.c in the USB core subsystem.
    This flaw allows a local attacker with a special user     or root privileges to crash the system due to a race     problem in the scatter-gather cancellation and transfer     completion in usb_sg_wait. This vulnerability can also     lead to a leak of internal kernel     information.(CVE-2020-12464)A memory overflow and data     corruption flaw were found in the Mediatek MT76 driver     module for WiFi in mt76_add_fragment in     driverset/wireless/mediatek/mt76/dma.c. An oversized     packet with too many rx fragments causes an overflow     and corruption in memory of adjacent pages. A local     attacker with a special user or root privileges can     cause a denial of service or a leak of internal kernel     information.(CVE-2020-12465)A vulnerability was found     in __mptctl_ioctl in drivers/message/fusion/mptctl.c in     Fusion MPT base driver 'mptctl' in the SCSI device     module, where an incorrect lock leads to a race     problem. This flaw allows an attacker with local access     and special user (or root) privileges to cause a denial     of service.(CVE-2020-12652)A flaw was found in the way     the mwifiex_cmd_append_vsie_tlv() in Linux kernel's     Marvell WiFi-Ex driver handled vendor specific     information elements. A local user could use this flaw     to escalate their privileges on the     system.(CVE-2020-12653)A flaw was found in the Linux     kernel. The Marvell mwifiex driver allows a remote WiFi     access point to trigger a heap-based memory buffer     overflow due to an incorrect memcpy operation. The     highest threat from this vulnerability is to data     integrity and system availability.(CVE-2020-12654)A     flaw was discovered in the XFS source in the Linux     kernel. This flaw allows an attacker with the ability     to mount an XFS filesystem, to trigger a denial of     service while attempting to sync a file located on an     XFS v5 image with crafted metadata.(CVE-2020-12655)An     out-of-bounds (OOB) memory access flaw was found in the     Network XDP (the eXpress Data Path) module in the Linux     kernel's xdp_umem_reg function in net/xdp/xdp_umem.c.
    When a user with special user privilege of     CAP_NET_ADMIN (or root) calls setsockopt to register     umem ring on XDP socket, passing the headroom value     larger than the available space in the chunk, it leads     to an out-of-bounds write, causing panic or possible     memory corruption. This flaw may lead to privilege     escalation if a local end-user is granted permission to     influence the execution of code in this     manner.(CVE-2020-12659)A vulnerability was found in     sg_write in drivers/scsi/sg.c in the SCSI generic (sg)     driver subsystem. This flaw allows an attacker with     local access and special user or root privileges to     cause a denial of service if the allocated list is not     cleaned with an invalid (Sg_fd * sfp) pointer at the     time of failure, also possibly causing a kernel     internal information leak problem.(CVE-2020-12770)An     issue was discovered in the Linux kernel through     5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation     fails.(CVE-2020-12771)A flaw was found in the Linux     kernel loose validation of child/parent process     identification handling while filtering signal     handlers. A local attacker is able to abuse this flaw     to bypass checks to send any signal to a privileged     process.(CVE-2020-12826)A flaw was found in the Linux     kernel, where it allows userspace processes, for     example, a guest VM, to directly access h/w devices via     its VFIO driver modules. The VFIO modules allow users     to enable or disable access to the devices' MMIO memory     address spaces. If a user attempts to access the     read/write devices' MMIO address space when it is     disabled, some h/w devices issue an interrupt to the     CPU to indicate a fatal error condition, crashing the     system. This flaw allows a guest user or process to     crash the host system resulting in a denial of     service.(CVE-2020-12888)gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)** DISPUTED ** An     issue was discovered in the Linux kernel through 5.7.1.
    drivers/tty/vt/keyboard.c has an integer overflow if     k_ascii is called several times in a row, aka     CID-b86dab054059. NOTE: Members in the community argue     that the integer overflow does not lead to a security     issue in this case.(CVE-2020-13974)A use-after-free     flaw was found in slcan_write_wakeup in     driverset/can/slcan.c in the serial CAN module slcan. A     race condition occurs when communicating with can using     slcan between the write (scheduling the transmit) and     closing (flushing out any pending queues) the SLCAN     channel. This flaw allows a local attacker with special     user or root privileges to cause a denial of service or     a kernel information leak. The highest threat from this     vulnerability is to system     availability.(CVE-2020-14416)In the Linux kernel     through 5.7.6, usbtest_disconnect in     drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)The Linux kernel     through 5.7.11 allows remote attackers to make     observations that help to obtain sensitive information     about the internal state of the network RNG, aka     CID-f227e3ec3b5c.

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):An issue was discovered in     the Linux kernel before 5.2. There is a NULL pointer     dereference in tw5864_handle_frame() in     drivers/media/pci/tw5864/tw5864-video.c, which may     cause denial of service, aka     CID-2e7682ebfc75.(CVE-2019-20806)A flaw was found in     the ZRAM kernel module, where a user with a local     account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)In the Linux kernel before     5.4.16, a race condition in tty->disc_data handling in     the slip and slcan line discipline could lead to a     use-after-free, aka CID-0ace17d56824. This affects     drivers/ net/slip/slip.c and drivers/     net/can/slcan.c.(CVE-2020-14416)The VFIO PCI driver in     the Linux kernel through 5.6.13 mishandles attempts to     access disabled memory space.(CVE-2020-12888)The     flow_dissector feature in the Linux kernel 4.3 through     5.x before 5.3.10 has a device tracking vulnerability,     aka CID-55667441c84f. This occurs because the auto     flowlabel of a UDP IPv6 packet relies on a 32-bit     hashrnd value as a secret, and because jhash (instead     of siphash) is used. The hashrnd value remains the same     starting from boot time, and can be inferred by an     attacker. This affects net/core/flow_dissector.c and     related code.(CVE-2019-18282)In the Linux kernel     through 5.7.6, usbtest_disconnect in     drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)An issue was     discovered in the Linux kernel before 5.0.6.

This update syncs the RT kernel from the SUSE Linux Enterprise 15-SP2 codestream. This update was imported from the SUSE:SLE-15-SP2:Update update project.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The Linux kernel through 5.7.11 allows remote attackers     to make observations that help to obtain sensitive     information about the internal state of the network     RNG, aka CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)

  - A flaw was found in the Linux kernel's implementation     of the invert video code on VGA consoles when a local     attacker attempts to resize the console, calling an     ioctl VT_RESIZE, which causes an out-of-bounds write to     occur. This flaw allows a local user with access to the     VGA console to crash the system, potentially escalating     their privileges on the system. The highest threat from     this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-14331)

  - A buffer over-read flaw was found in RH kernel versions     before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's     module, authenc. When a payload longer than 4 bytes,     and is not following 4-byte alignment boundary     guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local     attacker with user privileges to cause a denial of     service.(CVE-2020-10769)

  - An issue was discovered in the Linux kernel through     5.7.1. drivers/tty/vt/keyboard.c has an integer     overflow if k_ascii is called several times in a row,     aka CID-b86dab054059. NOTE: Members in the community     argue that the integer overflow does not lead to a     security issue in this case.(CVE-2020-13974)

  - In the Linux kernel through 5.7.6, usbtest_disconnect     in drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)

  - The VFIO PCI driver in the Linux kernel through 5.6.13     mishandles attempts to access disabled memory     space.(CVE-2020-12888)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - An issue was discovered in the Linux kernel before     5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a     reference count is mishandled, aka     CID-a3e23f719f5c.(CVE-2019-20811)

  - An issue was discovered in the Linux kernel before     5.4.7. The prb_calc_retire_blk_tmo() function in     net/packet/af_packet.c can result in a denial of     service (CPU consumption and soft lockup) in a certain     failure case involving TPACKET_V3, aka     CID-b43d1f9f7067.(CVE-2019-20812)

  - A flaw was found in the Linux kernel's implementation     of Userspace core dumps. This flaw allows an attacker     with a local account to crash a trivial program and     exfiltrate private kernel data.(CVE-2020-10732)

  - A flaw was found in the Linux kernels SELinux LSM hook     implementation before version 5.7, where it incorrectly     assumed that an skb would only contain a single netlink     message. The hook would incorrectly only validate the     first netlink message in the skb and allow or deny the     rest of the messages within the skb with the granted     permission without further processing.(CVE-2020-10751)

  - gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)

  - A signal access-control issue was discovered in the     Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32     bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process     can send an arbitrary signal to a parent process in a     different security domain. Exploitation limitations     include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where     signals to a parent process present a substantial     operational threat.(CVE-2020-12826)

  - The __mptctl_ioctl function in     drivers/message/fusion/mptctl.c in the Linux kernel     before 5.4.14 allows local users to hold an incorrect     lock during the ioctl operation and trigger a race     condition, i.e., a 'double fetch' vulnerability, aka     CID-28d76df18f0a. NOTE: the vendor states 'The security     impact of this bug is not as bad as it could have been     because these operations are all privileged and root     already has enormous destructive     power.'(CVE-2020-12652)

  - An issue was found in Linux kernel before 5.5.4. The     mwifiex_cmd_append_vsie_tlv() function in     drivers/net/wireless/marvell/mwifiex/scan.c allows     local users to gain privileges or cause a denial of     service because of an incorrect memcpy and buffer     overflow, aka CID-b70261a288ea.(CVE-2020-12653)

  - An issue was found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in     drivers/net/wireless/marvell/mwifiex/wmm.c allows a     remote AP to trigger a heap-based buffer overflow     because of an incorrect memcpy, aka     CID-3a9b153c5591.(CVE-2020-12654)

  - An issue was discovered in xfs_agf_verify in     fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through     5.6.10. Attackers may trigger a sync of excessive     duration via an XFS v5 image with crafted metadata, aka     CID-d0c7feaf8767.(CVE-2020-12655)

  - A flaw was found in the Linux kernel's implementation     of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the     system.(CVE-2020-10720)

  - An issue was discovered in the Linux kernel through     5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka     CID-83c6f2390040.(CVE-2020-12770)

  - In the Linux kernel before 5.4.12,     drivers/input/input.c has out-of-bounds writes via a     crafted keycode table, as demonstrated by     input_set_keycode, aka     CID-cb222aed03d7.(CVE-2019-20636)

  - An issue was discovered in the stv06xx subsystem in the     Linux kernel before 5.6.1.
    drivers/media/usb/gspca/stv06xx/stv06xx.c and     drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c     mishandle invalid descriptors, as demonstrated by a     NULL pointer dereference, aka     CID-485b06aadb93.(CVE-2020-11609)

  - In the netlink driver, there is a possible out of     bounds write due to a race condition. This could lead     to local escalation of privilege with System execution     privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-65025077(CVE-2020-0066)

  - In the Linux kernel before 5.5.8, get_raw_socket in     drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel     stack corruption via crafted system     calls.(CVE-2020-10942)

  - An issue was discovered in slc_bump in     drivers/net/can/slcan.c in the Linux kernel through     5.6.2. It allows attackers to read uninitialized     can_frame data, potentially containing sensitive     information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)

  - An issue was discovered in the Linux kernel through     5.6.2. mpol_parse_str in mm/mempolicy.c has a     stack-based out-of-bounds write because an empty     nodelist is mishandled during mount option parsing, aka     CID-aa9f7d5172fa. NOTE: Someone in the security     community disagrees that this is a vulnerability     because the issue 'is a bug in parsing mount options     which can only be specified by a privileged user, so     triggering the bug does not grant any powers not     already held.'.(CVE-2020-11565)

  - An issue was discovered in the Linux kernel before     5.6.1. drivers/media/usb/gspca/ov519.c allows NULL     pointer dereferences in ov511_mode_init_regs and     ov518_mode_init_regs when there are zero endpoints, aka     CID-998912346c0d.(CVE-2020-11608)

  - The kernel in Red Hat Enterprise Linux 7 and MRG-2 does     not clear garbage data for SG_IO buffer, which may     leaking sensitive information to     userspace.(CVE-2014-8181)

  - In the Linux kernel 5.0.21, mounting a crafted ext4     filesystem image, performing some operations, and     unmounting can lead to a use-after-free in     ext4_put_super in fs/ext4/super.c, related to     dump_orphan_list in fs/ext4/super.c.(CVE-2019-19447)
