RHEL 6 : mutt (RHSA-2011:0959)

This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An updated mutt package that fixes one security issue is now available
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.

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.
