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 :

  - In the ea_get function in fs/jfs/xattr.c in the Linux     kernel through 4.17.1, a memory corruption bug in JFS     can be triggered by calling setxattr twice with two     different extended attribute names on the same file.
    This vulnerability can be triggered by an unprivileged     user with the ability to create files and execute     programs. A kmalloc call is incorrect, leading to     slab-out-of-bounds in jfs_xattr.(CVE-2018-12233i1/4%0

  - The spectre_v2_select_mitigation function in     arch/x86/kernel/cpu/bugs.c in the Linux kernel before     4.18.1 does not always fill RSB upon a context switch,     which makes it easier for attackers to conduct     userspace-userspace spectreRSB     attacks.(CVE-2018-15572i1/4%0

  - Race condition in the queue_delete function in     sound/core/seq/seq_queue.c in the Linux kernel before     4.4.1 allows local users to cause a denial of service     (use-after-free and system crash) by making an ioctl     call at a certain time.(CVE-2016-2544i1/4%0

  - A flaw was found in the Linux kernel's implementation     of BPF in which systems can application can overflow a     32 bit refcount in both program and map refcount. This     refcount can wrap and end up a user after     free.(CVE-2016-4558i1/4%0

  - Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block     device.(CVE-2013-4299i1/4%0

  - The imon_probe function in drivers/media/rc/imon.c in     the Linux kernel through 4.13.11 allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16537i1/4%0

  - A vulnerability in the handling of Transactional Memory     on powerpc systems was found. An unprivileged local     user can crash the kernel by starting a transaction,     suspending it, and then calling any of the exec() class     system calls.(CVE-2016-5828i1/4%0

  - A cross-boundary flaw was discovered in the Linux     kernel software raid driver. The driver accessed a     disabled bitmap where only the first byte of the buffer     was initialized to zero. This meant that the rest of     the request (up to 4095 bytes) was left and copied into     user space. An attacker could use this flaw to read     private information from user space that would not     otherwise have been accessible.(CVE-2015-5697i1/4%0

  - The parse_hid_report_descriptor function in     drivers/input/tablet/gtco.c in the Linux kernel before     4.13.11 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-2017-16643i1/4%0

  - Race condition in the sclp_ctl_ioctl_sccb function in     drivers/s390/char/sclp_ctl.c in the Linux kernel before     4.6 allows local users to obtain sensitive information     from kernel memory by changing a certain length value,     aka a 'double fetch' vulnerability.(CVE-2016-6130i1/4%0

  - drivers/net/usb/asix_devices.c in the Linux kernel     through 4.13.11 allows local users to cause a denial of     service (NULL pointer dereference and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16647i1/4%0

  - A flaw was found in the Linux kernel which could cause     a kernel panic when restoring machine specific     registers on the PowerPC platform. Incorrect     transactional memory state registers could     inadvertently change the call path on return from     userspace and cause the kernel to enter an unknown     state and crash.(CVE-2015-8845i1/4%0

  - fs/namespace.c in the Linux kernel through 3.16.1 does     not properly restrict clearing MNT_NODEV, MNT_NOSUID,     and MNT_NOEXEC and changing MNT_ATIME_MASK during a     remount of a bind mount, which allows local users to     gain privileges, interfere with backups and auditing on     systems that had atime enabled, or cause a denial of     service (excessive filesystem updating) on systems that     had atime disabled via a 'mount -o remount' command     within a user namespace.(CVE-2014-5207i1/4%0

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in     denial of service.(CVE-2017-7645i1/4%0

  - The time subsystem in the Linux kernel, when     CONFIG_TIMER_STATS is enabled, allows local users to     discover real PID values (as distinguished from PID     values inside a PID namespace) by reading the     /proc/timer_list file, related to the print_timer     function in kernel/time/timer_list.c and the
    __timer_stats_timer_set_start_info function in     kernel/time/timer.c.(CVE-2017-5967i1/4%0

  - A vulnerability was found in the Linux kernel where the     keyctl_set_reqkey_keyring() function leaks the thread     keyring. This allows an unprivileged local user to     exhaust kernel memory and thus cause a     DoS.(CVE-2017-7472i1/4%0

  - A flaw was found that can be triggered in     keyring_search_iterator in keyring.c if type-i1/4zmatch     is NULL. A local user could use this flaw to crash the     system or, potentially, escalate their     privileges.(CVE-2017-2647i1/4%0

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911i1/4%0

  - Stack-based buffer overflow in the SET_WPS_IE IOCTL     implementation in wlan_hdd_hostapd.c in the WLAN (aka     Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used     in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to gain privileges via a crafted     application that uses a long WPS IE     element.(CVE-2015-0570i1/4%0

  - The net_ctl_permissions function in net/sysctl_net.c in     the Linux kernel before 3.11.5 does not properly     determine uid and gid values, which allows local users     to bypass intended /proc/sys/net restrictions via a     crafted application.(CVE-2013-4270i1/4%0

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.
