The SELECT element implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly restrict the nature or placement of HTML within a dropdown menu, which allows remote attackers to spoof the address bar or conduct clickjacking attacks via vectors that trigger navigation off of a page containing this element.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 25.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The txXPathNodeUtils::getBaseURI function in the XSLT processor in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 does not properly initialize data, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow and application crash) via crafted documents.

Use-after-free vulnerability in the nsIOService::NewChannelFromURIWithProxyFlags function in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code via vectors involving a blob: URL.

Use-after-free vulnerability in the nsContentUtils::ContentIsHostIncludingDescendantOf function in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving HTML document templates.

PDF.js in Mozilla Firefox before 25.0 and Firefox ESR 24.x before 24.1 does not properly handle the appending of an IFRAME element, which allows remote attackers to read arbitrary files or execute arbitrary JavaScript code with chrome privileges by using this element within an embedded PDF object.

Use-after-free vulnerability in the nsDocLoader::doStopDocumentLoad function in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving a state-change event during an update of the offline cache.

Unspecified vulnerability in the browser engine in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The JavaScript engine in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 does not properly allocate memory for unspecified functions, which allows remote attackers to conduct buffer overflow attacks via a crafted web page.

Use-after-free vulnerability in the nsAnimationManager::BuildAnimations function in the Animation Manager in Mozilla Firefox before 24.0, Firefox ESR 17.x before 17.0.9, Thunderbird before 24.0, Thunderbird ESR 17.x before 17.0.9, and SeaMonkey before 2.21 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving stylesheet cloning.
