The crypto.generateCRMFRequest function in Mozilla Firefox before 23.0, Firefox ESR 17.x before 17.0.8, Thunderbird before 17.0.8, Thunderbird ESR 17.x before 17.0.8, and SeaMonkey before 2.20 allows remote attackers to execute arbitrary JavaScript code or conduct cross-site scripting (XSS) attacks via vectors related to Certificate Request Message Format (CRMF) request generation.

Heap-based buffer underflow in the cryptojs_interpret_key_gen_type function in Mozilla Firefox before 23.0 and SeaMonkey before 2.20 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Certificate Request Message Format (CRMF) request.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 23.0, Firefox ESR 17.x before 17.0.8, Thunderbird before 17.0.8, Thunderbird ESR 17.x before 17.0.8, and SeaMonkey before 2.20 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 23.0, Firefox ESR 17.x before 17.0.8, Thunderbird before 17.0.8, Thunderbird ESR 17.x before 17.0.8, and SeaMonkey before 2.20 do not properly restrict local-filesystem access by Java applets, which allows user-assisted remote attackers to read arbitrary files by leveraging a download to a fixed pathname or other predictable pathname.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 23.0 and SeaMonkey before 2.20 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 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, and SeaMonkey before 2.17 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The System Only Wrapper (SOW) implementation in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, and SeaMonkey before 2.17 does not prevent use of the cloneNode method for cloning a protected node, which allows remote attackers to bypass the Same Origin Policy or possibly execute arbitrary JavaScript code with chrome privileges via a crafted web site.

Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, and SeaMonkey before 2.17 do not ensure the correctness of the address bar during history navigation, which allows remote attackers to conduct cross-site scripting (XSS) attacks or phishing attacks by leveraging control over navigation timing.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 20.0 and SeaMonkey before 2.17 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the nsContentUtils::HoldJSObjects function and the nsAutoPtr class, and other vectors.
