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 :

- bsc#971410: Scripts could terminate unexpectedly due to mishandled recursive traps.

- bsc#959755: Clarify that the files /etc/profile as well 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 has attempted to automatically clean and format it as much as possible without introducing additional issues.
