Cross-site request forgery 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. 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 via a crafted JPEG image. The nsIScriptableUnescapeHTML.parseFragment method in the ParanoidFragmentSink protection mechanism 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 does not properly sanitize HTML in a chrome document, which makes it easier for remote attackers to execute arbitrary JavaScript with chrome privileges via a javascript: URI in input to an extension, as demonstrated by a javascript:alert sequence in the HREF attribute of an A element or the ACTION attribute of a FORM element. 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 via a long string that triggers construction of a long text run. 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 exception timing and a large number of string values, aka an atom map 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 non-local JavaScript variables, aka an upvarMap issue. Use-after-free vulnerability in the JSON.stringify method 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. 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. Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 3.6.x before 3.6.14 and Thunderbird 3.1.x before 3.1.8 allow remote attackers to cause a denial of service or possibly execute arbitrary code via unknown vectors. Packages for 2009.0 are provided as of the Extended Maintenance Program
