Mozilla Firefox 2.x before 2.0.0.18 and SeaMonkey 1.x before 1.1.13 do not properly check when the Flash module has been dynamically unloaded properly, which allows remote attackers to execute arbitrary code via a crafted SWF file that "dynamically unloads itself from an outside JavaScript function," which triggers an access of an expired memory address.
jslock.cpp in Mozilla Firefox 3.x before 3.0.2, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying the window.__proto__.__proto__ object in a way that causes a lock on a non-native object, which triggers an assertion failure related to the OBJ_IS_NATIVE function.
Mozilla Firefox 3.x before 3.0.4 assigns chrome privileges to a file: URI when it is accessed in the same tab from a chrome or privileged about: page, which makes it easier for user-assisted attackers to execute arbitrary JavaScript with chrome privileges via malicious code in a file that has already been saved on the local system.
The layout engine in Mozilla Firefox 3.x before 3.0.4, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) via multiple vectors that trigger an assertion failure or other consequences.
Integer overflow in xpcom/io/nsEscape.cpp in the browser engine in Mozilla Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) via unknown vectors.
The JavaScript engine in Mozilla Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) via vectors related to "insufficient class checking" in the Date class.
The session restore feature in Mozilla Firefox 3.x before 3.0.4 and 2.x before 2.0.0.18 allows remote attackers to violate the same origin policy to conduct cross-site scripting (XSS) attacks and execute arbitrary JavaScript with chrome privileges via unknown vectors.
nsFrameManager in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying properties of a file input element while it is still being initialized, then using the blur method to access uninitialized memory.
The nsXMLHttpRequest::NotifyEventListeners method in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to bypass the same-origin policy and execute arbitrary script via multiple listeners, which bypass the inner window check.
Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to bypass the protection mechanism for codebase principals and execute arbitrary script via the -moz-binding CSS property in a signed JAR file.
