Use-after-free vulnerability in the nsEditor::IsPreformatted function in editor/libeditor/base/nsEditor.cpp in Mozilla Firefox before 19.0.2, Firefox ESR 17.x before 17.0.4, Thunderbird before 17.0.4, Thunderbird ESR 17.x before 17.0.4, and SeaMonkey before 2.16.1 allows remote attackers to execute arbitrary code via vectors involving an execCommand call.
Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 do not prevent multiple wrapping of WebIDL objects, which allows remote attackers to bypass intended access restrictions via unspecified vectors.
The RasterImage::DrawFrameTo function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and application crash) via a crafted GIF image.
The Chrome Object Wrapper (COW) and System Only Wrapper (SOW) implementations in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 do not prevent modifications to a prototype, which allows remote attackers to obtain sensitive information from chrome objects or possibly execute arbitrary JavaScript code with chrome privileges via a crafted web site.
Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 do not prevent JavaScript workers from reading the browser-profile directory name, which has unspecified impact and remote attack vectors.
Use-after-free vulnerability in the nsImageLoadingContent::OnStopContainer function in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code via crafted web script.
Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allow man-in-the-middle attackers to spoof the address bar by operating a proxy server that provides a 407 HTTP status code accompanied by web script, as demonstrated by a phishing attack on an HTTPS site.
Use-after-free vulnerability in the nsDisplayBoxShadowOuter::Paint function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.
The ClusterIterator::NextCluster function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via unspecified vectors.
The nsCodingStateMachine::NextState function in Mozilla Firefox before 19.0, Thunderbird before 17.0.3, and SeaMonkey before 2.16 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via unspecified vectors.
