• Ubuntu 12.10
• Ubuntu 12.04
• Ubuntu 10.04

Packages

• 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.
