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.

Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.10 and SeaMonkey before 1.1.7 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors that trigger memory corrupti

Mozilla Firefox before 2.0.0.10 and SeaMonkey 1.1.7 sets the Referer header to the window or frame in which script is running, instead of the address of the content that initiated the script, which allows remote attackers to spoof HTTP Referer headers and bypass Referer-based CSRF protection schemes by setting window.location and using a modal alert dialog that causes the wrong Referer to be sent.
