mutt - buffer overflow

Byrial Jensen discovered a couple of off-by-one buffer overflow in the
IMAP code of Mutt, a text-oriented mail reader supporting IMAP, MIME,
GPG, PGP and threading. This problem could potentially allow a remote
malicious IMAP server to cause a denial of service (crash) and
possibly execute arbitrary code via a specially crafted mail folder.

For the stable distribution (woody) this problem has been fixed in
version 1.3.28-2.2.

The old stable distribution (potato) is also affected by this problem
and an update will follow.

For the unstable distribution (sid) this problem has been fixed in
version 1.4.0 and above.

We recommend that you upgrade your mutt package.
