Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, does not properly implement autocompletion for forms, which allows remote attackers to read form history entries via a Java applet that spoofs interaction with the autocomplete controls.

Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, does not properly use nsTreeRange data structures, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to a "dangling pointer."

Unspecified vulnerability in the Java Embedding Plugin (JEP) in Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, on Mac OS X allows remote attackers to bypass intended access restrictions via unknown vectors.

Use-after-free vulnerability in Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, allows remote attackers to execute arbitrary code via vectors related to OBJECT's mObserverList.

The txXPathNodeUtils::getXSLTId function in txMozillaXPathTreeWalker.cpp and txStandaloneXPathTreeWalker.cpp in Mozilla Firefox before 3.5.19, 3.6.x before 3.6.17, and 4.x before 4.0.1, and SeaMonkey before 2.0.14, allows remote attackers to obtain potentially sensitive information about heap memory addresses via an XML document containing a call to the XSLT generate-id XPath function.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, does not properly handle certain recursive eval calls, which makes it easier for remote attackers to force a user to respond positively to a dialog question, as demonstrated by a question about granting privileges.

Use-after-free vulnerability in the JSON.stringify method in js3250.dll in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, might allow remote attackers to execute arbitrary code via unspecified vectors related to the js_HasOwnProperty function and garbage collection.

Buffer overflow in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, on Windows allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a long string that triggers construction of a long text run.

Buffer overflow in Mozilla Firefox 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 might allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted JPEG image.
