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 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 uvc_scan_chain_forward     of uvc_driver.c, there is a possible linked list     corruption due to an unusual root cause. This could     lead to local escalation of privilege in the kernel     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID:
    A-111893654References: Upstream kernel.(CVE-2020-0404)A     flaw was found in the Linux kernel in versions from     2.2.3 through 5.9.rc5. When changing screen size, an     out-of-bounds memory write can occur leading to memory     corruption or a denial of service. This highest threat     from this vulnerability is to system     availability.(CVE-2020-14390)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 fs4proc.c instead of fsfs4xdr.c, aka     CID-b4487b935452.(CVE-2020-25212)A flaw was found in     the Linux kernel before 5.9-rc4. A failure of the file     system metadata validator in XFS can cause an inode     with a valid, user-creatable extended attribute to be     flagged as corrupt. This can lead to the filesystem     being shutdown, or otherwise rendered inaccessible     until it is remounted, leading to a denial of service.
    The highest threat from this vulnerability is to system     availability.(CVE-2020-14385)In the Linux kernel before     5.7.8, fsfsd/vfs.c (in the NFS server) can set     incorrect permissions on new filesystem objects when     the filesystem lacks ACL support, aka CID-22cf8419f131.
    This occurs because the current umask is not     considered.(CVE-2020-24394)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)An issue was     discovered in net/ipv4/sysctl_net_ipv4.c in the Linux     kernel before 5.0.11. There is a net/ipv4/tcp_input.c     signed integer overflow in tcp_ack_update_rtt() when     userspace writes a very large integer to /proc/sys     et/ipv4/tcp_min_rtt_wlen, leading to a denial of     service or possibly unspecified other impact, aka     CID-19fad20d15a6.(CVE-2019-18805)Insufficient input     validation in i40e driver for Intel(R) Ethernet 700     Series Controllers versions before 7.0 may allow an     authenticated user to potentially enable a denial of     service via local access.(CVE-2019-0147)Buffer overflow     in i40e driver for Intel(R) Ethernet 700 Series     Controllers versions before 7.0 may allow an     authenticated user to potentially enable an escalation     of privilege via local access.(CVE-2020-0145)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 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 missing CAP_NET_RAW     check in NFC socket creation in net fc/rawsock.c in the     Linux kernel before 5.8.2 could be used by local     attackers to create raw sockets, bypassing security     mechanisms, aka CID-26896f01467a.(CVE-2020-26088)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)The Linux kernel, as used     in Red Hat Enterprise Linux 7, kernel-rt, and     Enterprise MRG 2 and when booted with UEFI Secure Boot     enabled, allows local users to bypass intended     securelevel/secureboot restrictions by leveraging     improper handling of secure_boot flag across kexec     reboot.(CVE-2015-7837)A flaw was found in the Linux     kernel's implementation of biovecs in versions before     5.9-rc7. A zero-length biovec request issued by the     block subsystem could cause the kernel to enter an     infinite loop, causing a denial of service. This flaw     allows a local attacker with basic privileges to issue     requests to a block device, resulting in a denial of     service. The highest threat from this vulnerability is     to system availability.(CVE-2020-25641)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)A flaw was found in the Linux     kernel in versions before 5.9-rc7. Traffic between two     Geneve endpoints may be unencrypted when IPsec is     configured to encrypt traffic for the specific UDP port     used by the GENEVE tunnel allowing anyone between the     two endpoints to read the traffic unencrypted. The main     threat from this vulnerability is to data     confidentiality.(CVE-2020-25645)perf: Fix race in     perf_mmap_close function.(CVE-2020-14351)An information     leak flaw was found in the way the Linux kernel's     Bluetooth stack implementation handled initialization     of stack memory when handling certain AMP packets. A     remote attacker in adjacent range could use this flaw     to leak small portions of stack memory on the system by     sending a specially crafted AMP packets. The highest     threat from this vulnerability is to data     confidentiality.(CVE-2020-12352)A flaw was found in the     way the Linux kernel Bluetooth implementation handled     L2CAP packets with A2MP CID. A remote attacker in     adjacent range could use this flaw to crash the system     causing denial of service or potentially execute     arbitrary code on the system by sending a specially     crafted L2CAP packet. The highest threat from this     vulnerability is to data confidentiality and integrity     as well as system availability.(CVE-2020-12351)A heap     buffer overflow flaw was found in the way the Linux     kernel's Bluetooth implementation processed extended     advertising report events. This flaw allows a remote     attacker in an adjacent range to crash the system,     causing a denial of service or to potentially execute     arbitrary code on the system by sending a specially     crafted Bluetooth packet. The highest threat from this     vulnerability is to confidentiality, integrity, as well     as system availability.(CVE-2020-24490)** RESERVED **     This candidate has been reserved by an organization or     individual that will use it when announcing a new     security problem. When the candidate has been     publicized, the details for this candidate will be     provided.(CVE-2020-25656)In skb_to_mamac of     networking.c, there is a possible out of bounds write     due to an integer overflow. This could lead to local     escalation of privilege with no additional execution     privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-143560807(CVE-2020-0432)A     slab-out-of-bounds read in fbcon in the Linux kernel     before 5.9.7 could be used by local attackers to read     privileged information or potentially crash the kernel,     aka CID-3c4e0dff2095. This occurs because     KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for     manipulations such as font height.(CVE-2020-28974)A     flaw memory leak in the Linux kernel performance     monitoring subsystem was found in the way if using     PERF_EVENT_IOC_SET_FILTER. A local user could use this     flaw to starve the resources causing denial of     service.(CVE-2020-25704)A buffer over-read (at the     framebuffer layer) in the fbcon code in the Linux     kernel before 5.8.15 could be used by local attackers     to read kernel memory, aka     CID-6735b4632def.(CVE-2020-28915)There is a     use-after-free problem seen 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 device tracking vulnerability     was found in the flow_dissector feature in the Linux     kernel. This flaw occurs because the auto flowlabel of     the UDP IPv6 packet relies on a 32-bit hashmd value as     a secret, and jhash (instead of siphash) is used. The     hashmd value remains the same starting from boot time     and can be inferred by an     attacker.(CVE-2019-18282)Use-after-free vulnerability     in fs/block_dev.c in the Linux kernel before 5.8 allows     local users to gain privileges or cause a denial of     service by leveraging improper access to a certain     error field.(CVE-2020-15436)The Linux kernel before     version 5.8 is vulnerable to a NULL pointer dereference     in     drivers/tty/serial/8250/8250_core.c:serial8250_isa_init
    _ports() that allows local users to cause a denial of     service by using the p->serial_in pointer which     uninitialized.(CVE-2020-15437)An issue was discovered     in kmem_cache_alloc_bulk in mm/slub.c in the Linux     kernel before 5.5.11. The slowpath lacks the required     TID increment, aka CID-fd4d9c7d0c71.(CVE-2020-29370)An     issue was discovered in the Linux kernel before 5.2.6.
    On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault     statistics are inappropriately freed, aka     CID-16d51a590a8c.(CVE-2019-20934)An issue was     discovered in romfs_dev_read in fs/romfs/storage.c in     the Linux kernel before 5.8.4. Uninitialized memory     leaks to userspace, aka     CID-bcf85fcedfdd.(CVE-2020-29371)An issue was     discovered in the Linux kernel before 5.7.3, related to     mm/gup.c and mm/huge_memory.c. The get_user_pages (aka     gup) implementation, when used for a copy-on-write     page, does not properly consider the semantics of read     operations and therefore can grant unintended write     access, aka CID-17839856fd58.(CVE-2020-29374)A flaw was     found in the way RTAS handled memory accesses in     userspace to kernel communication. On a locked down     (usually due to Secure Boot) guest system running on     top of PowerVM or KVM hypervisors (pseries platform) a     root like local user could use this flaw to further     increase their privileges to that of a running     kernel.(CVE-2020-27777)In kbd_keycode of keyboard.c,     there is a possible out of bounds write due to a     missing bounds check. This could lead to local     escalation of privilege with no additional execution     privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-144161459(CVE-2020-0431)

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 version of AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)
