Heap-based buffer overflow in Mozilla Firefox before 1.5.0.7, Thunderbird before 1.5.0.7, and SeaMonkey before 1.0.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a JavaScript regular expression with a "minimal quantifier."
Mozilla Firefox before 1.5.0.7, Thunderbird before 1.5.0.7, and SeaMonkey before 1.0.5 allows remote attackers to cause a denial of service (crash) via a malformed JavaScript regular expression that ends with a backslash in an unterminated character set ("[\\"), which leads to a buffer over-read.
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 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via simultaneous XPCOM events, which causes a timer object to be deleted in a way that triggers memory corruption.
Mozilla Firefox 1.5 before 1.5.0.5 and SeaMonkey before 1.0.3 does not properly clear a JavaScript reference to a frame or window, which leaves a pointer to a deleted object that allows remote attackers to execute arbitrary native code.
Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to hijack native DOM methods from objects in another domain and conduct cross-site scripting (XSS) attacks using DOM methods of the top-level object.
The Javascript engine in Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 might allow remote attackers to execute arbitrary code via vectors involving garbage collection that causes deletion of a temporary object that is still being used.
Mozilla Firefox before 1.5.0.5 and SeaMonkey before 1.0.3 allows remote Proxy AutoConfig (PAC) servers to execute code with elevated privileges via a PAC script that sets the FindProxyForURL function to an eval method on a privileged object.
Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows scripts with the UniversalBrowserRead privilege to gain UniversalXPConnect privileges and possibly execute code or obtain sensitive data by reading into a privileged context.
Cross-site scripting (XSS) vulnerability in Mozilla Firefox 1.5 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to inject arbitrary web script or HTML via the XPCNativeWrapper(window).Function construct.
