NVD Description

Note: Versions mentioned in the description apply only to the upstream thunderbird-debuginfo package and not the thunderbird-debuginfo package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
