Updated mutt package fixes security vulnerability

A heap-based buffer overflow flaw was found in the way mutt processed certain email headers. A remote attacker could use this flaw to send an email with specially crafted headers that, when processed, could cause mutt to crash or, potentially, execute arbitrary code with the permissions of the user running mutt (CVE-2014-0467).
