Package : bash
Version : 4.1-3+deb6u2
CVE ID : CVE-2014-7169
Debian Bug : 762760 762761

Tavis Ormandy discovered that the patch applied to fix CVE-2014-6271
released in DSA-3032-1 for bash, the GNU Bourne-Again Shell, was
incomplete and could still allow some characters to be injected into
another environment (CVE-2014-7169). With this update prefix and suffix
for environment variable names which contain shell functions are added
as hardening measure.

Additionally two out-of-bounds array accesses in the bash parser are
fixed which were revealed in Red Hat's internal analysis for these
issues and also independently reported by Todd Sabin.
