The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:2772 advisory.

  - kernel: Infoleak/use-after-free in __oom_reap_task_mm function in mm/oom_kill.c (CVE-2017-18202)

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

リモートの Redhat Enterprise Linux 7 ホストにインストールされているパッケージは、RHSA-2018: 2772 のアドバイザリに記載されている脆弱性の影響を受けます。

  - kernel: mm/oom_kill.c の __oom_reap_task_mm 関数における情報漏洩/メモリ解放後使用 (use-after-free) (CVE-2017-18202)

Nessus はこの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

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 __oom_reap_task_mm function in mm/oom_kill.c in the     Linux kernel, before 4.14.4, mishandles gather     operations. This allows attackers to cause a denial of     service (TLB entry leak or use-after-free) or possibly     have unspecified other impact by triggering a     copy_to_user call within a certain time     window.(CVE-2017-18202i1/4%0

  - Buffer overflow in the qeth_snmp_command function in     drivers/s390/net/qeth_core_main.c in the Linux kernel     through 3.12.1 allows local users to cause a denial of     service or possibly have unspecified other impact via     an SNMP ioctl call with a length value that is     incompatible with the command-buffer     size.(CVE-2013-6381i1/4%0

  - It was discovered that the Linux kernel since 3.6-rc1     with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG()     statement in tcp_collapse() function after making a     number of certain syscalls leading to a possible system     crash.(CVE-2016-8645i1/4%0

  - It was found that the Linux kernel's implementation of     vectored pipe read and write functionality did not take     into account the I/O vectors that were already     processed when retrying after a failed atomic access     operation, potentially resulting in memory corruption     due to an I/O vector array overrun. A local,     unprivileged user could use this flaw to crash the     system or, potentially, escalate their privileges on     the system.(CVE-2015-1805i1/4%0

  - The Linux kernel is vulnerable to an out-of-bounds read     in ext4/balloc.c:ext4_valid_block_bitmap() function. An     attacker could trick a legitimate user or a privileged     attacker could exploit this by mounting a crafted ext4     image to cause a crash.(CVE-2018-1093i1/4%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.
