mutt vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10

Summary:
The mutt mail client could be made to crash if it opened a specially
crafted email.
Software Description:
- 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.
