USN-2440-1: Mutt vulnerability
11 December 2014
The mutt mail client could be made to crash if it opened a specially crafted email.
Releases
Packages
- mutt - text-based mailreader supporting MIME, GPG, PGP and threading
Details
Jakub Wilk discovered that the write_one_header function in mutt
did not properly handle newline characters at the beginning of a
header. An attacker could specially craft an email to cause mutt to
crash, resulting in a denial of service.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04
Ubuntu 10.04
After a standard system update you need to restart any running
instances of mutt to make all the necessary changes.
