Mozilla Firefox and Thunderbird Auto-update DNS spoofing

mozilla-auto-update-dns-spoofing (28950) The risk level is classified as MediumMedium Risk

Description:

Mozilla Firefox and Thunderbird could allow a remote attacker to gain unauthorized access to a victim's system, caused by a vulnerability in the Auto-update mechanism that does not adequately protect against DNS spoofing. If an attacker could spoof a victim's DNS server, the attacker could gain unauthorized access to the victim's system if the victim accepts the attacker's certificate for the Mozilla update site.
