High Nessus Plugin ID 117990

Synopsis

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

Description

The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive a
security fix.

The following security bug was fixed :

CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c
mishandled sequence number overflows. An attacker can trigger a
use-after-free (and possibly gain privileges) via certain thread
creation, map, unmap, invalidation, and dereference operations
(bnc#1108399).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution
