The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver [firewire-net] in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since version     2.6.31 (year 2009) till version v4.9-rc4. A maliciously     formed fragment with a respectively large datagram     offset would cause a memcpy() past the datagram buffer,     which would cause a system panic or possible arbitrary     code execution. The flaw requires [firewire-net] module     to be loaded and is remotely exploitable from connected     firewire devices, but not over a local network.
    (CVE-2016-8633)

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIMIT_INFINITY, but does not take the     argument and environment pointers into account, which     allows attackers to bypass this limitation.
    (CVE-2017-1000365)

  - A bug in the 32-bit compatibility layer of the ioctl     handling code of the v4l2 video driver in the Linux     kernel has been found. A memory protection mechanism     ensuring that user-provided buffers always point to a     userspace memory were disabled, allowing destination     address to be in a kernel space. This flaw could be     exploited by an attacker to overwrite a kernel memory     from an unprivileged userspace process, leading to     privilege escalation. (CVE-2017-13166)

  - The timer_create syscall implementation in     kernel/time/posix-timers.c in the Linux kernel doesn't     properly validate the sigevent->sigev_notify field,     which leads to out-of-bounds access in the show_timer     function. (CVE-2017-18344)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5715 triggers the     speculative execution by utilizing branch target     injection. It relies on the presence of a precisely-     defined instruction sequence in the privileged code as     well as the fact that memory accesses may cause     allocation into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to cross the syscall and guest/host     boundaries and read privileged memory by conducting     targeted cache side-channel attacks. (CVE-2017-5715)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5753 triggers the     speculative execution by performing a bounds-check     bypass. It relies on the presence of a precisely-defined     instruction sequence in the privileged code as well as     the fact that memory accesses may cause allocation into     the microprocessor's data cache even for speculatively     executed instructions that never actually commit     (retire). As a result, an unprivileged attacker could     use this flaw to cross the syscall boundary and read     privileged memory by conducting targeted cache side-     channel attacks. (CVE-2017-5753)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5754 relies on the     fact that, on impacted microprocessors, during     speculative execution of instruction permission faults,     exception generation triggered by a faulting access is     suppressed until the retirement of the whole instruction     block. In a combination with the fact that memory     accesses may populate the cache even when the block is     being dropped and never committed (executed), an     unprivileged local attacker could use this flaw to read     privileged (kernel space) memory by conducting targeted     cache side-channel attacks. Note: CVE-2017-5754 affects     Intel x86-64 microprocessors. AMD x86-64 microprocessors     are not affected by this issue. (CVE-2017-5754)

  - A use-after-free vulnerability was found in DCCP socket     code affecting the Linux kernel since 2.6.16. This     vulnerability could allow an attacker to their escalate     privileges. (CVE-2017-8824)

  - It was found that the raw midi kernel driver does not     protect against concurrent access which leads to a     double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation. (CVE-2018-10902)

  - A vulnerability was found in the     fs/inode.c:inode_init_owner() function logic of the     LInux kernel that allows local users to create files     with an unintended group ownership and with group     execution and SGID permission bits set, in a scenario     where a directory is SGID and belongs to a certain group     and is writable by a user who is not a member of this     group. This can lead to excessive permissions granted in     case when they should not. (CVE-2018-13405)

  - An integer overflow flaw was found in the Linux kernel's     create_elf_tables() function. An unprivileged local user     with access to SUID (or otherwise privileged) binary     could use this flaw to escalate their privileges on the     system. (CVE-2018-14634)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of Load & Store instructions (a commonly used     performance optimization). It relies on the presence of     a precisely-defined instruction sequence in the     privileged code as well as the fact that memory read     from address to which a recent memory write has occurred     may see an older value and subsequently cause an update     into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to read privileged memory by     conducting targeted cache side-channel attacks.
    (CVE-2018-3639)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions past bounds check. The flaw     relies on the presence of a precisely-defined     instruction sequence in the privileged code and the fact     that memory writes occur to an address which depends on     the untrusted value. Such writes cause an update into     the microprocessor's data cache even for speculatively     executed instructions that never actually commit     (retire). As a result, an unprivileged attacker could     use this flaw to influence speculative execution and/or     read privileged memory by conducting targeted cache     side-channel attacks. (CVE-2018-3693)

  - A flaw named SegmentSmack was found in the way the Linux     kernel handled specially crafted TCP packets. A remote     attacker could use this flaw to trigger time and     calculation expensive calls to tcp_collapse_ofo_queue()     and tcp_prune_ofo_queue() functions by sending specially     modified packets within ongoing TCP sessions which could     lead to a CPU saturation and hence a denial of service     on the system. Maintaining the denial of service     condition requires continuous two-way TCP sessions to a     reachable open port, thus the attacks cannot be     performed using spoofed IP addresses. (CVE-2018-5390)

  - A flaw named FragmentSmack was found in the way the     Linux kernel handled reassembly of fragmented IPv4 and     IPv6 packets. A remote attacker could use this flaw to     trigger time and calculation expensive fragment     reassembly algorithm by sending specially crafted     packets which could lead to a CPU saturation and hence a     denial of service on the system. (CVE-2018-5391)

  - A an integer overflow vulnerability was discovered in     the Linux kernel, from version 3.4 through 4.15, in the     drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An     attacker with access to the udldrmfb driver could     exploit this to obtain full read and write permissions     on kernel physical pages, resulting in a code execution     in kernel space. (CVE-2018-8781)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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

  - The function hso_get_config_data in     drivers/net/usb/hso.c in the Linux kernel through     4.19.8 reads if_num from the USB device (as a u8) and     uses it to index a small array, resulting in an object     out-of-bounds (OOB) read that potentially allows     arbitrary read in the kernel address     space.(CVE-2018-19985)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions (a commonly used performance     optimization). There are three primary variants of the     issue which differ in the way the speculative execution     can be exploited. Variant CVE-2017-5754 relies on the     fact that, on impacted microprocessors, during     speculative execution of instruction permission faults,     exception generation triggered by a faulting access is     suppressed until the retirement of the whole     instruction block. In a combination with the fact that     memory accesses may populate the cache even when the     block is being dropped and never committed (executed),     an unprivileged local attacker could use this flaw to     read privileged (kernel space) memory by conducting     targeted cache side-channel attacks. Note:
    CVE-2017-5754 affects Intel x86-64 microprocessors. AMD     x86-64 microprocessors are not affected by this     issue.(CVE-2017-5754)

  - A non-privileged user is able to mount a fuse     filesystem on RHEL 6 or 7 and crash a system if an     application punches a hole in a file that does not end     aligned to a page boundary.(CVE-2017-15121)

  - A flaw was found in the Linux kernel when attempting to     'punch a hole' in files existing on an ext4 filesystem.
    When punching holes into a file races with the page     fault of the same area, it is possible that freed     blocks remain referenced from page cache pages mapped     to process' address space.(CVE-2015-8839)

  - An industry-wide issue was found in the way many modern     microprocessor designs have implemented speculative     execution of instructions past bounds check. The flaw     relies on the presence of a precisely-defined     instruction sequence in the privileged code and the     fact that memory writes occur to an address which     depends on the untrusted value. Such writes cause an     update into the microprocessor's data cache even for     speculatively executed instructions that never actually     commit (retire). As a result, an unprivileged attacker     could use this flaw to influence speculative execution     and/or read privileged memory by conducting targeted     cache side-channel attacks.(CVE-2018-3693)

  - A Floating Point Unit (FPU) state information leakage     flaw was found in the way the Linux kernel saved and     restored the FPU state during task switch. Linux     kernels that follow the 'Lazy FPU Restore' scheme are     vulnerable to the FPU state information leakage issue.
    An unprivileged local attacker could use this flaw to     read FPU state bits by conducting targeted cache     side-channel attacks, similar to the Meltdown     vulnerability disclosed earlier this     year.(CVE-2018-3665)

  - A bug in the 32-bit compatibility layer of the ioctl     handling code of the v4l2 video driver in the Linux     kernel has been found. A memory protection mechanism     ensuring that user-provided buffers always point to a     userspace memory were disabled, allowing destination     address to be in a kernel space. This flaw could be     exploited by an attacker to overwrite a kernel memory     from an unprivileged userspace process, leading to     privilege escalation.(CVE-2017-13166)

  - It was found that the raw midi kernel driver does not     protect against concurrent access which leads to a     double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)

  - A flaw was found in the Linux kernel's implementation     of valid_master_desc() in which a memory buffer would     be compared to a userspace value with an incorrect size     of comparison. By bruteforcing the comparison, an     attacker could determine what was in memory after the     description and possibly obtain sensitive information     from kernel memory.(CVE-2017-13305)

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound write in in     fs/jbd2/transaction.c code, a denial of service, and a     system crash by unmounting a crafted ext4 filesystem     image.(CVE-2018-10882)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:0415 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * kernel: MIDI driver race condition leads to a double-free (CVE-2018-10902)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * Previously backported upstream patch caused a change in the behavior of page fault handler. As a     consequence, applications compiled through GNU Compiler Collection (GCC) version 4.4.7 sometimes generated     stack access exceeding the 64K limit. Running such applications subsequently triggered a segmentation     fault. With this update, the 64k limit check in the page fault handler has been removed. As a result,     running the affected applications no longer triggers the segmentation fault in the described scenario.

    Note that removing the limit check does not impact the integrity of the kernel itself. (BZ#1644401)

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 Linux     kernel in the ext4 filesystem code. A use-after-free is     possible in ext4_ext_remove_space() function when     mounting and operating a crafted ext4     image.(CVE-2018-10876)A flaw was found in the Linux     kernel. A use-after-free was found in the way the     console subsystem was using ioctls KDGKBSENT and     KDSKBSENT. A local user could use this flaw to get read     memory access out of bounds. The highest threat from     this vulnerability is to data     confidentiality.(CVE-2020-25656)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)A information disclosure     vulnerability in the Upstream kernel encrypted-keys.
    Product: Android. Versions: Android kernel. Android ID:
    A-70526974.(CVE-2017-13305)A race condition was found     in the Linux kernels implementation of the floppy disk     drive controller driver software. The impact of this     issue is lessened by the fact that the default     permissions on the floppy device (/dev/fd0) are     restricted to root. If the permissions on the device     have changed the impact changes greatly. In the default     configuration root (or equivalent) permissions are     required to attack this flaw.(CVE-2021-20261)An issue     was discovered in dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of     prop->name, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash).(CVE-2019-12614)An issue was discovered in     fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3.
    There is a NULL pointer dereference and panic in     lookup_slow() on a NULL inode->i_ops pointer when doing     pathwalks on a corrupted xfs image. This occurs because     of a lack of proper validation that cached inodes are     free during allocation.(CVE-2018-13093)An issue was     discovered in rds_tcp_kill_sock in net/rds/tcp.c in the     Linux kernel before 5.0.8. There is a race condition     leading to a use-after-free, related to net namespace     cleanup.(CVE-2019-11815)An issue was discovered in the     Linux kernel through 5.11.3. A kernel pointer leak can     be used to determine the address of the iscsi_transport     structure. When an iSCSI transport is registered with     the iSCSI subsystem, the transport's handle is     available to unprivileged users via the sysfs file     system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)An issue was     discovered in the Linux kernel through 5.11.3. Certain     iSCSI data structures do not have appropriate length     constraints or checks, and can exceed the PAGE_SIZE     value. An unprivileged user can send a Netlink message     that is associated with iSCSI, and has a length up to     the maximum length of a Netlink     message.(CVE-2021-27365)An issue was discovered in the     Linux kernel through 5.11.3.
    drivers/scsi/scsi_transport_iscsi.c is adversely     affected by the ability of an unprivileged user to     craft Netlink messages.(CVE-2021-27364)An issue was     discovered in yurex_read in drivers/usb/misc/yurex.c in     the Linux kernel before 4.17.7. Local attackers could     use user access read/writes with incorrect bounds     checking in the yurex USB driver to crash the kernel or     potentially escalate     privileges.(CVE-2018-16276)drivers/infiniband/core/ucma     .c in the Linux kernel through 4.17.11 allows     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allows     attackers to cause a denial of service     (use-after-free).(CVE-2018-14734)In create_pinctrl of     core.c, there is a possible out of bounds read due to a     use after free. This could lead to local information     disclosure with no additional execution privileges     needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-140550171(CVE-2020-0427)In     do_epoll_ctl and ep_loop_check_proc of eventpoll.c,     there is a possible use after free due to a logic     error. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for exploitation.Product:

This could lead to the size-remaining variable     wrapping and the data pointer going over the end of the     buffer. This could possibly lead to memory corruption     and possible privilege escalation.(CVE-2017-7482)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)In various methods of     hid-multitouch.c, there is a possible out of bounds     write due to a missing bounds check.

A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)Linux kernel ext4     filesystem is vulnerable to an out-of-bound access in     the ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)Linux     kernel is vulnerable to a stack-out-of-bounds write in     the ext4 filesystem code when mounting and writing to a     crafted ext4 image in ext4_update_inline_data(). An     attacker could use this to cause a system crash and a     denial of service.(CVE-2018-10880)Linux Kernel contains     an out-of-bounds read flaw in the asn1_ber_decoder()     function in lib/asn1_decoder.c that is triggered when     decoding ASN.1 data. This may allow a remote attacker     to disclose potentially sensitive memory     contents.(CVE-2018-9383)use-after-free read in     sunkbd_reinit in     drivers/input/keyboard/sunkbd.c(CVE-2020-25669)mwifiex_     cmd_802_11_ad_hoc_start in drivers/     net/wireless/marvell/mwifiex/join.c in the Linux kernel     through 5.10.4 might allow remote attackers to execute     arbitrary code via a long SSID value, aka     CID-5c455c5ab332.(CVE-2020-36158)fs/ nfsd/ nfs3xdr.c in     the Linux kernel through 5.10.8, when there is an NFS     export of a subdirectory of a filesystem, allows remote     attackers to traverse to other parts of the filesystem     via READDIRPLUS. NOTE: some parties argue that such a     subdirectory export is not intended to prevent this     attack see also the exports(5) no_subtree_check default     behavior.(CVE-2021-3178)In the Linux kernel before     4.20.8, kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a     use-after-free.(CVE-2019-6974)The KVM implementation in     the Linux kernel through 4.20.5 has a     Use-after-Free.(CVE-2019-7221)A flaw was found in the     JFS filesystem code. This flaw allows a local attacker     with the ability to set extended attributes to panic     the system, causing memory corruption or escalating     privileges. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-27815)An out-of-bounds (OOB)     memory access flaw was found in x25_bind in     net/x25/af_x25.c in the Linux kernel. A bounds check     failure allows a local attacker with a user account on     the system to gain access to out-of-bounds memory,     leading to a system crash or a leak of internal kernel     information. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-35519)In     drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)A NULL pointer     dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before     4.14.7 allowing local attackers to cause a system panic     and a denial-of-service, related to RDS_GET_MR and     RDS_GET_MR_FOR_DEST.(CVE-2018-7492)The Siemens R3964     line discipline driver in drivers/tty/ n_r3964.c in the     Linux kernel before 5.0.8 has multiple race     conditions.(CVE-2019-11486)The kernel in Android before     2016-08-05 on Nexus 7 (2013) devices allows attackers     to gain privileges via a crafted application, aka     internal bug 28522518.(CVE-2016-3857)The KVM     implementation in the Linux kernel through 4.14.7     allows attackers to obtain potentially sensitive     information from kernel memory, aka a write_mmio     stack-based out-of-bounds read, related to     arch/x86/kvm/x86.c and     include/trace/events/kvm.h.(CVE-2017-17741)The     sctp_process_param function in net/sctp/sm_make_chunk.c     in the SCTP implementation in the Linux kernel before     3.17.4, when ASCONF is used, allows remote attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a malformed INIT     chunk.(CVE-2014-7841)The XFS subsystem in the Linux     kernel through 4.8.2 allows local users to cause a     denial of service (fdatasync failure and system hang)     by using the vfs syscall group in the trinity program,     related to a 'page lock order bug in the XFS seek     hole/data implementation.'(CVE-2016-8660)The     xfs_dinode_verify function in     fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel     through 4.16.3 allows local users to cause a denial of     service (xfs_ilock_attr_map_shared invalid pointer     dereference) via a crafted xfs image.(CVE-2018-10322)
