USN-2147-1: Mutt vulnerability

13 March 2014

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



  • mutt - text-based mailreader supporting MIME, GPG, PGP and threading


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:

Ubuntu 13.10
Ubuntu 12.10
Ubuntu 12.04
Ubuntu 10.04

After a standard system update you need to restart mutt to make
all the necessary changes.
