SUSE SLED12 / SLES12 Security Update : bash (SUSE-SU-2017:1317-1)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

This update for bash fixes an issue that could lead to syntax errors
when parsing scripts that use expr(1) inside loops. Additionally, the
popd build-in now ensures that the normalized stack offset is within
bounds before trying to free that stack entry. This fixes a
segmentation fault.

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.
