USN-2147-1: Mutt vulnerability
Ubuntu Security Notice USN-2147-1
13th March, 2014
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
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.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.10:
- mutt-patched 1.5.21-6.4ubuntu1.1
- mutt 1.5.21-6.4ubuntu1.1
- Ubuntu 12.10:
- mutt-patched 1.5.21-6ubuntu0.1
- mutt 1.5.21-6ubuntu0.1
- Ubuntu 12.04 LTS:
- mutt-patched 1.5.21-5ubuntu2.1
- mutt 1.5.21-5ubuntu2.1
- Ubuntu 10.04 LTS:
- mutt-patched 1.5.20-7ubuntu1.2
- mutt 1.5.20-7ubuntu1.2
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to restart mutt to make
all the necessary changes.
