RHEL 6 : mutt (RHSA-2011:0959)

Medium Nessus Plugin ID 55626


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


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.


Update the affected mutt and / or mutt-debuginfo packages.
