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.
