for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

Mutt is a text-mode mail user agent.

A flaw was found in the way Mutt verified SSL certificates. When a
server presented an SSL certificate chain, Mutt could ignore a server
hostname check failure. A remote attacker able to get a certificate
from a trusted Certificate Authority could use this flaw to trick Mutt
into accepting a certificate issued for a different hostname, and
perform man-in-the-middle attacks against Mutt's SSL connections.
(CVE-2011-1429)

All Mutt users should upgrade to this updated package, which contains
a backported patch to correct this issue. All running instances of
Mutt must be restarted for this update to take effect."
