| Mozilla Firefox before 3.0.11, Thunderbird before 2.0.0.22, and
SeaMonkey before 1.1.17 use the HTTP Host header to determine the
context of a document provided in a non-200 CONNECT response from a
proxy server, which allows man-in-the-middle attackers to execute
arbitrary web script by modifying this CONNECT response, aka an "SSL
tampering" attack.
