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

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

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

  - The sanity_check_raw_super function in fs/f2fs/super.c in the Linux kernel before 4.11.1 does not validate     the segment count, which allows local users to gain privileges via unspecified vectors. (CVE-2017-10662)

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

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 :

  - A double free vulnerability was found in netlink_dump,     which could cause a denial of service or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9806i1/4%0

  - Memory leak in drivers/media/video/videobuf-core.c in     the videobuf subsystem in the Linux kernel 2.6.x     through 4.x allows local users to cause a denial of     service (memory consumption) by leveraging /dev/video     access for a series of mmap calls that require new     allocations, a different vulnerability than     CVE-2007-6761. NOTE: as of 2016-06-18, this affects     only 11 drivers that have not been updated to use     videobuf2 instead of videobuf.(CVE-2010-5321i1/4%0

  - ** 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-2018-1108i1/4%0

  - The KVM implementation in the Linux kernel through     4.20.5 has an Information Leak.(CVE-2019-7222i1/4%0

  - The adreno_perfcounter_query_group function in     drivers/gpu/msm/adreno_perfcounter.c in the Adreno GPU     driver for the Linux kernel 3.x, as used in Qualcomm     Innovation Center (QuIC) Android contributions for MSM     devices and other products, uses an incorrect integer     data type, which allows attackers to cause a denial of     service (integer overflow, heap-based buffer overflow,     and incorrect memory allocation) or possibly have     unspecified other impact via a crafted     IOCTL_KGSL_PERFCOUNTER_QUERY ioctl     call.(CVE-2016-2062i1/4%0

  - drivers/hid/hid-ntrig.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_NTRIG is enabled, allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and OOPS) via a crafted     device.(CVE-2013-2896i1/4%0

  - The wacom_probe function in     drivers/input/tablet/wacom_sys.c in the Linux kernel     before 3.17 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-3139i1/4%0

  - An integer overflow vulnerability in     ip6_find_1stfragopt() function was found. A local     attacker that has privileges (of CAP_NET_RAW) to open     raw socket can cause an infinite loop inside the     ip6_find_1stfragopt() function.(CVE-2017-7542i1/4%0

  - Memory leak in the virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel through 4.11.8 allows attackers to cause a     denial of service (memory consumption) by triggering     object-initialization failures.(CVE-2017-10810i1/4%0

  - The ping_recvmsg function in net/ipv4/ping.c in the     Linux kernel before 3.12.4 does not properly interact     with read system calls on ping sockets, which allows     local users to cause a denial of service (NULL pointer     dereference and system crash) by leveraging unspecified     privileges to execute a crafted     application.(CVE-2013-6432i1/4%0

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208i1/4%0

  - An issue was discovered in the Linux kernel through     4.18.8. The vmacache_flush_all function in     mm/vmacache.c mishandles sequence number overflows. An     attacker can trigger a use-after-free (and possibly     gain privileges) via certain thread creation, map,     unmap, invalidation, and dereference     operations.(CVE-2018-17182i1/4%0

  - The ieee80211_radiotap_iterator_init function in     net/wireless/radiotap.c in the Linux kernel before     3.11.7 does not check whether a frame contains any data     outside of the header, which might allow attackers to     cause a denial of service (buffer over-read) via a     crafted header.(CVE-2013-7027i1/4%0

  - The Btrfs implementation in the Linux kernel before     3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows     local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1)     during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement     attempt that fails because the data does not     fit.(CVE-2014-9710i1/4%0

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled duplicate Address Configuration Change Chunks     (ASCONF). A remote attacker could use either of these     flaws to crash the system.(CVE-2014-3687i1/4%0

  - A syntax vulnerability was discovered in the kernel's     ASN1.1 DER decoder, which could lead to memory     corruption or a complete local denial of service     through x509 certificate DER files. A local system user     could use a specially created key file to trigger     BUG_ON() in the public_key_verify_signature() function     (crypto/asymmetric_keys/public_key.c), to cause a     kernel panic and crash the system.(CVE-2016-2053i1/4%0

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invept     (Invalidate Translations Derived from EPT)     instructions. On hosts with an Intel processor and     invept VM exit support, an unprivileged guest user     could use these instructions to crash the     guest.(CVE-2014-3645i1/4%0

  - The packet_recvmsg function in net/packet/af_packet.c     in the Linux kernel before 3.12.4 updates a certain     length value before ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7270i1/4%0

  - The init_new_context function in     arch/x86/include/asm/mmu_context.h in the Linux kernel,     before 4.12.10, does not correctly handle errors from     LDT table allocation when forking a new process. This     could allow a local attacker to achieve a     use-after-free or possibly have unspecified other     impact by running a specially crafted     program.(CVE-2017-17053i1/4%0

  - It was found that the sanity_check_raw_super() function     in 'fs/f2fs/super.c' file in the Linux kernel before     version 4.12-rc1 does not validate the f2fs filesystem     segment count. This allows an unprivileged local user     to cause a system panic and DoS. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2017-10662i1/4%0
