Summer Institute of Linguistics (SIL) Graphite 2, as used in Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to the (1) Silf::readClassMap and (2) Pass::readPass functions.
Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12 do not prevent use of the Object.defineProperty method to shadow the location object (aka window.location), which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via vectors involving a plugin.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to garbage collection after certain MethodJIT execution, and unknown other vectors.
Use-after-free vulnerability in the nsHTMLEditor::CollapseAdjacentTextNodes function in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.
Use-after-free vulnerability in the nsObjectLoadingContent::LoadObject function in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.
Mozilla Firefox 4.x through 13.0, Firefox ESR 10.x before 10.0.6, Thunderbird 5.0 through 13.0, Thunderbird ESR 10.x before 10.0.6, and SeaMonkey before 2.11 do not properly handle duplicate values in X-Frame-Options headers, which makes it easier for remote attackers to conduct clickjacking attacks via a FRAME element referencing a web site that produces these duplicate values.
Use-after-free vulnerability in the JSDependentString::undepend function in Mozilla Firefox 4.x through 13.0, Firefox ESR 10.x before 10.0.6, Thunderbird 5.0 through 13.0, Thunderbird ESR 10.x before 10.0.6, and SeaMonkey before 2.11 allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via vectors involving strings with multiple dependencies.
The Content Security Policy (CSP) functionality in Mozilla Firefox 4.x through 13.0, Firefox ESR 10.x before 10.0.6, Thunderbird 5.0 through 13.0, Thunderbird ESR 10.x before 10.0.6, and SeaMonkey before 2.11 does not properly restrict the strings placed into the blocked-uri parameter of a violation report, which allows remote web servers to capture OpenID credentials and OAuth 2.0 access tokens by triggering a violation.
The certificate-warning functionality in browser/components/certerror/content/aboutCertError.xhtml in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.6, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.6, and SeaMonkey before 2.10 does not properly handle attempted clickjacking of the about:certerror page, which allows man-in-the-middle attackers to trick users into adding an unintended exception via an IFRAME element.
