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.

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 IPv6 SCTP implementation in net/sctp/ipv6.c in the     Linux kernel through 3.11.1 uses data structures and     function calls that do not trigger an intended     configuration of IPsec encryption, which allows remote     attackers to obtain sensitive information by sniffing     the network.(CVE-2013-4350i1/4%0

  - The sg_ioctl function in drivers/scsi/sg.c in the Linux     kernel allows local users to cause a denial of service     (stack-based buffer overflow) or possibly have     unspecified other impacts via a large command size in     an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds     write access in the sg_write function.(CVE-2017-7187i1/4%0

  - An issue was discovered in can_can_gw_rcv in     net/can/gw.c in the Linux kernel through 4.19.13. The     CAN frame modification rules allow bitwise logical     operations that can be also applied to the can_dlc     field. Because of a missing check, the CAN drivers may     write arbitrary content beyond the data registers in     the CAN controller's I/O memory when processing can-gw     manipulated outgoing frames. This is related to     cgw_csum_xor_rel. An unprivileged user can trigger a     system crash (general protection     fault).(CVE-2019-3701i1/4%0

  - net/rds/sysctl.c in the Linux kernel before 3.19 uses     an incorrect data type in a sysctl table, which allows     local users to obtain potentially sensitive information     from kernel memory or possibly have unspecified other     impact by accessing a sysctl entry.(CVE-2015-2042i1/4%0

  - The inet_csk_clone_lock function in     net/ipv4/inet_connection_sock.c in the Linux kernel     allows attackers to cause a denial of service (double     free) or possibly have unspecified other impact by     leveraging use of the accept system call. An     unprivileged local user could use this flaw to induce     kernel memory corruption on the system, leading to a     crash. Due to the nature of the flaw, privilege     escalation cannot be fully ruled out, although we     believe it is unlikely.(CVE-2017-8890i1/4%0

  - The overlayfs implementation in the linux (aka Linux     kernel) package before 3.19.0-21.21 in Ubuntu through     15.04 does not properly check permissions for file     creation in the upper filesystem directory, which     allows local users to obtain root access by leveraging     a configuration in which overlayfs is permitted in an     arbitrary mount namespace.(CVE-2015-1328i1/4%0

  - 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-2018-10322i1/4%0

  - In the flush_tmregs_to_thread function in     arch/powerpc/kernel/ptrace.c in the Linux kernel before     4.13.5, a guest kernel crash can be triggered from     unprivileged userspace during a core dump on a POWER     host due to a missing processor feature check and an     erroneous use of transactional memory (TM) instructions     in the core dump path, leading to a denial of     service.(CVE-2018-1091i1/4%0

  - ** DISPUTED ** drivers/scsi/libsas/sas_scsi_host.c in     the Linux kernel before 4.16 allows local users to     cause a denial of service (ata qc leak) by triggering     certain failure conditions. NOTE: a third party     disputes the relevance of this report because the     failure can only occur for physically proximate     attackers who unplug SAS Host Bus Adapter     cables.(CVE-2018-10021i1/4%0

  - A use-after-free flaw was discovered in the Linux     kernel's tty subsystem, which allows for the disclosure     of uncontrolled memory location and possible kernel     panic. The information leak is caused by a race     condition when attempting to set and read the tty line     discipline. A local attacker could use the TIOCSETD     (via tty_set_ldisc ) to switch to a new line discipline     a concurrent call to a TIOCGETD ioctl performing a read     on a given tty could then access previously allocated     memory. Up to 4 bytes could be leaked when querying the     line discipline or the kernel could panic with a     NULL-pointer dereference.(CVE-2016-0723i1/4%0

  - An out-of-bounds read flaw was found in the way the     Logitech Unifying receiver driver handled HID reports     with an invalid device_index value. An attacker with     physical access to the system could use this flaw to     crash the system or, potentially, escalate their     privileges on the system.(CVE-2014-3182i1/4%0

  - arch/x86/kvm/emulate.c in the Linux kernel through     4.9.3 allows local users to obtain sensitive     information from kernel memory or cause a denial of     service (use-after-free) via a crafted application that     leverages instruction emulation for fxrstor, fxsave,     sgdt, and sidt.(CVE-2017-2584i1/4%0

  - A flaw was found in the way the Linux kernel handled     IRET faults during the processing of NMIs. An     unprivileged, local user could use this flaw to crash     the system or, potentially (although highly unlikely),     escalate their privileges on the     system.(CVE-2015-5157i1/4%0

  - drivers/media/media-device.c in the Linux kernel before     3.11, as used in Android before 2016-08-05 on Nexus 5     and 7 (2013) devices, does not properly initialize     certain data structures, which allows local users to     obtain sensitive information via a crafted application,     aka Android internal bug 28750150 and Qualcomm internal     bug CR570757, a different vulnerability than     CVE-2014-1739.(CVE-2014-9895i1/4%0

  - A use-after-free vulnerability in sys_ioprio_get() was     found due to get_task_ioprio() accessing the     task-i1/4zio_context without holding the task lock and     could potentially race with exit_io_context(), leading     to a use-after-free.(CVE-2016-7911i1/4%0

  - A flaw was found in the Linux kernel which is related     to the user namespace lazily unmounting file systems.
    The fs_pin struct has two members (m_list and s_list)     which are usually initialized on use in the     pin_insert_group function. However, these members might     go unmodified in this case, the system panics when it     attempts to destroy or free them. This flaw could be     used to launch a denial-of-service     attack.(CVE-2015-4178i1/4%0

  - A flaw was found in the Linux kernel's implementation     of raw_sendmsg allowing a local attacker to panic the     kernel or possibly leak kernel addresses. A local     attacker, with the privilege of creating raw sockets,     can abuse a possible race condition when setting the     socket option to allow the kernel to automatically     create ip header values and thus potentially escalate     their privileges.(CVE-2017-17712i1/4%0

  - A flaw was discovered in the F2FS filesystem code in     fs/f2fs/super.c in the Linux kernel. A denial of     service, due to an out-of-bounds memory access, can     occur upon encountering an abnormal bitmap size when     mounting a crafted f2fs image.(CVE-2018-13096i1/4%0

  - A NULL pointer dereference flaw was found in the way     the Linux kernel's madvise MADV_WILLNEED functionality     handled page table locking. A local, unprivileged user     could use this flaw to crash the     system.(CVE-2014-8173i1/4%0

  - An out-of-bounds heap memory access leading to a Denial     of Service, heap disclosure, or further impact was     found in setsockopt(). The function call is normally     restricted to root, however some processes with     cap_sys_admin may also be able to trigger this flaw in     privileged container environments.(CVE-2016-4998i1/4%0
