mutt vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

The mutt mail client could be made to crash or run programs as your
login if it opened a specially crafted email.

Software Description:
- mutt: text-based mailreader supporting MIME, GPG, PGP and threading

Details:

Beatrice Torracca and Evgeni Golov discovered a buffer overflow
in mutt while expanding addresses when parsing email headers. An
attacker could specially craft an email to cause mutt to crash,
resulting in a denial of service, or possibly execute arbitrary code
with the privileges of the user invoking mutt.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:
