Description

The jar protocol handler in Mozilla Firefox before 2.0.0.10 and SeaMonkey before 1.1.7 retrieves the inner URL regardless of its MIME type, and considers HTML documents within a jar archive to have the same origin as the inner URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a jar: URI.

Affected products

Mozilla Firefox: through 2.0.0.9; 2.0.0.1, 2.0.0.2, 2.0.0.3, 2.0.0.4, 2.0.0.5, 2.0.0.6 (+2)
Mozilla Seamonkey: through 1.1.6; 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5
