Michal Zalewski discovered that Bash incorrectly handled parsing certain
function definitions. If an attacker were able to create an environment
variable containing a function definition with a very specific name, these
issues could possibly be used to bypass certain environment restrictions
and execute arbitrary code. (CVE-2014-6277, CVE-2014-6278)
Please note that the previous Bash security update, USN-2364-1, includes
a hardening measure that prevents these issues from being used in a
Shellshock attack.
