Mandriva Linux Security Advisory : bash (MDVSA-2012:128)

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


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.
