high Nessus Plugin ID 152842

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2846-1 advisory.

This update for the Linux Kernel 4.4.180-94_147 fixes several issues.

The following security issues were fixed:

- CVE-2021-37576: On the powerpc platform KVM guest OS users could cause host OS memory corruption via rtas_args.nargs (bsc#1188838).
- CVE-2021-28688: The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. (bsc#1183646)
- CVE-2020-0429: Fixed a potential local privilege escalation in l2tp_session_delete and related functions of l2tp_core.c (bsc#1176724).

Tenable has extracted the preceding description block directly from the SUSE 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 affected kgraft-patch-4_4_180-94_147-default package.
