Scientific Linux Security Update : mutt on SL6.x i386/x86_64

Medium Nessus Plugin ID 61085


The remote Scientific Linux host is missing one or more security updates.


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.
