Details

Florian Weimer and Todd Sabin discovered that the Bash parser incorrectly
handled memory. An attacker could possibly use this issue to bypass certain
environment restrictions and execute arbitrary code. (CVE-2014-7186,
CVE-2014-7187)

In addition, this update introduces a hardening measure which adds prefixes
and suffixes around environment variable names which contain shell
functions.
