Description

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
