Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2827-1 advisory.

 The following security bugs were fixed:

 - CVE-2020-36557: Fixed race condition between the VT_DISALLOCATE ioctl and closing/opening of ttys that could lead to a use-after-free (bnc#1201429).
 - CVE-2020-36558: Fixed race condition involving VT_RESIZEX that could lead to a NULL pointer dereference and general protection fault (bnc#1200910).

 - CVE-2022-36946: Fixed incorrect packet truncation in nfqnl_mangle() that could lead to remote DoS (bnc#1201940).


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 packages.
