Mandriva Linux Security Advisory : bash (MDVSA-2014:190)

Critical Nessus Plugin ID 77950

Synopsis

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

Description

It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. An attacker could potentially use this flaw to override or bypass environment restrictions to execute shell commands. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue (CVE-2014-7169, CVE-2014-7186, CVE-2014-7187).

Additionally bash has been updated from patch level 37 to 48 using the upstream patches at ftp://ftp.gnu.org/gnu/bash/bash-4.2-patches/ which resolves various bugs.

Solution

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