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

  - 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

  - 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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002821 advisory.

    The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc     platforms mishandles transactional state, which allows local users to cause a denial of service (invalid     process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by     starting and suspending a transaction before an exec system call.

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

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

The SUSE Linux Enterprise 12 GA LTSS kernel was updated to 3.12.61 to receive various security and bugfixes. The following feature was implemented :

  - The ext2 filesystem got reenabled and supported to allow     support for 'XIP' (Execute In Place) (FATE#320805). The     following security bugs were fixed :

  - CVE-2017-5551: The tmpfs filesystem implementation in     the Linux kernel preserved the setgid bit during a     setxattr call, which allowed local users to gain group     privileges by leveraging the existence of a setgid     program with restrictions on execute permissions     (bsc#1021258).

  - CVE-2016-7097: The filesystem implementation in the     Linux kernel preserved the setgid bit during a setxattr     call, which allowed local users to gain group privileges     by leveraging the existence of a setgid program with     restrictions on execute permissions (bnc#995968).

  - CVE-2017-2583: A Linux kernel built with the     Kernel-based Virtual Machine (CONFIG_KVM) support was     vulnerable to an incorrect segment selector(SS) value     error. A user/process inside guest could have used this     flaw to crash the guest resulting in DoS or potentially     escalate their privileges inside guest. (bsc#1020602).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux     kernel allowed 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 (bnc#1019851).

  - CVE-2016-10088: The sg implementation in the Linux     kernel did not properly restrict write operations in     situations where the KERNEL_DS option is set, which     allowed local users to read or write to arbitrary kernel     memory locations or cause a denial of service     (use-after-free) by leveraging access to a /dev/sg     device, related to block/bsg.c and drivers/scsi/sg.c.
    NOTE: this vulnerability exists because of an incomplete     fix for CVE-2016-9576 (bnc#1017710).

  - CVE-2016-8645: The TCP stack in the Linux kernel     mishandled skb truncation, which allowed local users to     cause a denial of service (system crash) via a crafted     application that made sendto system calls, related to     net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c     (bnc#1009969).
