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 acpi_smbus_hc_add function in drivers/acpi/sbshc.c     in the Linux kernel through 4.14.15 allows local users     to obtain sensitive address information by reading     dmesg data from an SBS HC printk call.(CVE-2018-5750i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. A use-after-free is possible in     try_merge_free_space() when mounting a crafted btrfs     image due to a lack of chunk type flag checks in     btrfs_check_chunk_valid() in the fs/btrfs/volumes.c     function. This could lead to a denial of service or     other unspecified impact.(CVE-2018-14611i1/4%0

  - A flaw was found in the way the Linux kernel visor     driver handles certain invalid USB device descriptors.
    The driver assumes that the device always has at least     one bulk OUT endpoint. By using a specially crafted USB     device (without a bulk OUT endpoint), an unprivileged     user with physical access could trigger a kernel     NULL-pointer dereference and cause a system panic     (denial of service).(CVE-2015-7566i1/4%0

  - It was found that the RFC 5961 challenge ACK rate     limiting as implemented in the Linux kernel's     networking subsystem allowed an off-path attacker to     leak certain information about a given connection by     creating congestion on the global challenge ACK rate     limit counter and then measuring the changes by probing     packets. An off-path attacker could use this flaw to     either terminate TCP connection and/or inject payload     into non-secured TCP connection between two endpoints     on the network.(CVE-2016-5696i1/4%0

  - It was found that the Bluebooth Network Encapsulation     Protocol (BNEP) implementation did not validate the     type of second socket passed to the BNEPCONNADD     ioctl(), which could lead to memory corruption. A local     user with the CAP_NET_ADMIN capability can use this for     denial of service (crash or data corruption) or     possibly for privilege escalation. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we feel it is unlikely.(CVE-2017-15868i1/4%0

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299i1/4%0

  - The rfcomm_sock_bind function in     net/bluetooth/rfcomm/sock.c in the Linux kernel before     4.2 allows local users to obtain sensitive information     or cause a denial of service (NULL pointer dereference)     via vectors involving a bind system call on a Bluetooth     RFCOMM socket.(CVE-2015-8956i1/4%0

  - arch/mips/include/asm/thread_info.h in the Linux kernel     before 3.14.8 on the MIPS platform does not configure
    _TIF_SECCOMP checks on the fast system-call path, which     allows local users to bypass intended PR_SET_SECCOMP     restrictions by executing a crafted application without     invoking a trace or audit subsystem.(CVE-2014-4157i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem     code. A stack-out-of-bounds write in     ext4_update_inline_data() is possible when mounting and     writing to a crafted ext4 image. An attacker could use     this to cause a system crash and a denial of     service.(CVE-2018-10880i1/4%0

  - The aac_send_raw_srb function in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     through 3.12.1 does not properly validate a certain     size value, which allows local users to cause a denial     of service (invalid pointer dereference) or possibly     have unspecified other impact via an     FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted     SRB command.(CVE-2013-6380i1/4%0

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to an uncaught     exception issue. It could occur if an L2 guest was to     throw an exception which is not handled by an L1     guest.(CVE-2016-9588i1/4%0

  - A flaw was found in the alarm_timer_nsleep() function     in kernel/time/alarmtimer.c in the Linux kernel. The     ktime_add_safe() function is not used and an integer     overflow can happen causing an alarm not to fire if     using a large relative timeout.(CVE-2018-13053i1/4%0

  - net/llc/sysctl_net_llc.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-2015-2041i1/4%0

  - Incorrect error handling in the set_mempolicy() and     mbind() compat syscalls in 'mm/mempolicy.c' in the     Linux kernel allows local users to obtain sensitive     information from uninitialized stack data by triggering     failure of a certain bitmap operation.(CVE-2017-7616i1/4%0

  - The snd_msnd_interrupt function in     sound/isa/msnd/msnd_pinnacle.c in the Linux kernel     through 4.11.7 allows local users to cause a denial of     service (over-boundary access) or possibly have     unspecified other impact by changing the value of a     message queue head pointer between two kernel reads of     that value, aka a 'double fetch'     vulnerability.(CVE-2017-9984i1/4%0

  - An integer overflow was discovered in the     qla2x00_sysfs_write_optrom_ctl function in     drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel     through 4.12.10. This flaw allows local users to cause     a denial of service (memory corruption and system     crash) by leveraging root access.(CVE-2017-14051i1/4%0

  - A use-after-free flaw was found in the way the Linux     kernel's Advanced Linux Sound Architecture (ALSA)     implementation handled user controls. A local,     privileged user could use this flaw to crash the     system.(CVE-2014-4654i1/4%0

  - An information leak flaw was found in the way the Linux     kernel's Virtual Dynamic Shared Object (vDSO)     implementation performed address randomization. A     local, unprivileged user could use this flaw to leak     kernel memory addresses to user-space.(CVE-2014-9585i1/4%0

  - The usbhid_parse function in     drivers/hid/usbhid/hid-core.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (out-of-bounds read and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16533i1/4%0

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106i1/4%0

  - CVE-2017-15274: security/keys/keyctl.c in the Linux     kernel did not consider the case of a NULL payload in     conjunction with a nonzero length value, which allowed     local users to cause a denial of service (NULL pointer     dereference and OOPS) via a crafted add_key or keyctl     system call, a different vulnerability than     CVE-2017-12192 (bnc#1045327).
