Summary

Mutt is a text-mode mail user agent.
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)
All mutt users are advised to upgrade to this updated package, which contains a backported patch to correct this issue. All running instances of mutt must be restarted for this update to take effect.
