NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not properly handle HTTP responses that contain multiple Location, Content-Length, or Content-Disposition headers, which makes it easier for remote attackers to conduct HTTP response splitting attacks via crafted header values.
