Red Hat: 2014:0304-01: mutt: Important Advisory
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.
