high Nessus Plugin ID 131981

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:4164 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: Memory corruption due to incorrect socket cloning (CVE-2018-9568)

* kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members (CVE-2018-13405)

* Kernel: page cache side channel attacks (CVE-2019-5489)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* kernel build: parallelize redhat/mod-sign.sh (BZ#1755325)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL kernel package based on the guidance in RHSA-2019:4164.
