Synopsis :

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

Description :

This update for bash fixes the following issues :

- CVE-2016-7543: Local attackers could have executed
arbitrary commands via specially crafted SHELLOPTS+PS4
variables. (bsc#1001299)

- CVE-2016-0634: Malicious hostnames could have allowed
arbitrary command execution when $HOSTNAME was expanded
in the prompt. (bsc#1000396) The following bugs were
fixed :

mishandled recursive traps.

as /etc/bash.bashrc may source other files as well even
if the bash does not.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable

without introducing additional issues.
