The nsXMLDocument::OnChannelRedirect function in Mozilla Firefox before 2.0.0.17, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allows remote attackers to bypass the Same Origin Policy and execute arbitrary JavaScript code via unknown vectors.
Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allow remote attackers to create documents that lack script-handling objects, and execute arbitrary code with chrome privileges, via vectors related to (1) the document.loadBindingDocument function and (2) XSLT.
Multiple vulnerabilities in the layout engine for Mozilla Firefox 1.5.x before 1.5.0.12 and 2.x before 2.0.0.4, Thunderbird 1.5.x before 1.5.0.12 and 2.x before 2.0.0.4, and SeaMonkey 1.0.9 and 1.1.2 allow remote attackers to cause a denial of service (crash) via vectors related to dangling pointers, heap corruption, signed/unsigned, and other issues.
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 and Thunderbird before 1.5.0.4 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) nested <option> tags in a select tag, (2) a DOMNodeRemoved mutation event, (3) "Content-implemented tree views," (4) BoxObjects, (5) the XBL implementation, (6) an iframe that attempts to remove itself, which leads to memory corruption.
