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

medium Nessus Plugin ID 100246

Language:

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.
