Mozilla Firefox and SeaMonkey alternate names spoofing

mozilla-altnames-spoofing (43524) The risk level is classified as MediumMedium Risk

Description:

Mozilla Firefox and SeaMonkey are vulnerable to spoofing attacks, caused by an error when processing alternate names on peer certificates. An attacker could exploit this vulnerability using man-in-the-middle techniques to spoof a self-signed certificate containing alternate site names and redirect a user to a malicious Web site that would appear to be trusted. This could allow the attacker to obtain sensitive information that could be used to launch further attacks against the victim's system.
