medium Nessus Plugin ID 61977

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

A vulnerability was found and corrected in bash :

A stack-based buffer overflow flaw was found in the way bash, the GNU Bourne Again shell, expanded certain /dev/fd file names when checking file names ('test' command) and evaluating /dev/fd file names in conditinal command expressions. A remote attacker could provide a specially crafted Bash script that, when executed, would cause the bash executable to crash (CVE-2012-3410).

Additionally the official patches 011 to 037 for bash-4.2 has been applied which resolves other issues found, including the CVE-2012-3410 vulnerability.

Solution

Update the affected bash and / or bash-doc packages.
