503578: CVE-2009-1836 Firefox SSL tampering via non-200 responses to proxy CONNECT requests

The MITRE CVE dictionary describes this issue as:

Mozilla Firefox before 3.0.11, Thunderbird before, 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.
