Multiple unspecified vulnerabilities in the layout engine in Mozilla Firefox before 1.5.0.10 and 2.x before 2.0.0.2, Thunderbird before 1.5.0.10, and SeaMonkey before 1.0.8 allow remote attackers to cause a denial of service (crash) and potentially execute arbitrary code via certain vectors.

Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to reference remote files and possibly load chrome: URLs by tricking the user into copying or dragging links.

Mozilla Firefox 1.5.0.4 and earlier allows remote user-assisted attackers to cause a denial of service (crash) via a form with a multipart/form-data encoding and a user-uploaded file. NOTE: a third party has claimed that this issue might be related to the LiveHTTPHeaders extension.

DISPUTED Mozilla Firefox 1.5.0.1, and possibly other versions, preserves some records of user activity even after uninstalling, which allows local users who share a Windows profile to view the records after a new installation of Firefox, as reported for the list of Passwords Never Saved web sites. NOTE: The vendor has disputed this issue, stating that "The uninstaller is primarily there to uninstall the application. It is not there to uninstall user data. For the moment I will stick by my module-owner decision."
