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.

Use-after-free vulnerability in the Web Workers implementation in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, allows remote attackers to execute arbitrary code via vectors related to a JavaScript Worker and garbage collection.

Buffer overflow in the JavaScript engine 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 vectors involving non-local JavaScript variables, aka an "upvarMap" issue.

Buffer overflow in the JavaScript engine 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 vectors involving exception timing and a large number of string values, aka an "atom map" issue.

Cross-site request forgery (CSRF) vulnerability in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, allows remote attackers to hijack the authentication of arbitrary users for requests that were initiated by a plugin and received a 307 redirect to a page on a different web site.

Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly calculate index values for certain child content in a XUL tree, which allows remote attackers to execute arbitrary code via vectors involving a DIV element within a treechildren element.
