The nsScannerString::AppendUnicodeTo function in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 does not verify that memory allocation succeeds, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via crafted Unicode data in an HTML, XML, or SVG document.

Use-after-free vulnerability in the AtomicBaseIncDec function in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) by leveraging mishandling of XML transformations.

Use-after-free vulnerability in the nsHTMLDocument::SetBody function in dom/html/nsHTMLDocument.cpp in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to execute arbitrary code by leveraging mishandling of a root element, aka ZDI-CAN-3574.

Integer underflow in the nsHtml5TreeBuilder class in the HTML5 string parser in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) by leveraging mishandling of end tags, as demonstrated by incorrect SVG processing, aka ZDI-CAN-3545.

The CairoTextureClientD3D9::BorrowDrawTarget function in the Direct3D 9 implementation in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 reads data from uninitialized memory locations, which has unspecified impact and attack vectors.

nsZipArchive.cpp in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 accesses unintended memory locations, which allows remote attackers to have an unspecified impact via a crafted ZIP archive.

Buffer overflow in the nsXMLHttpRequest::AppendToResponseText function in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 might allow remote attackers to cause a denial of service or have unspecified other impact via unknown vectors.

The nsZipArchive::BuildFileList function in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 accesses unintended memory locations, which allows remote attackers to have an unspecified impact via a crafted ZIP archive.

The ArrayBufferBuilder::append function in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 accesses unintended memory locations, which has unspecified impact and attack vectors.

The YCbCrImageDataDeserializer::ToDataSourceSurface function in the YCbCr implementation in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 reads data from uninitialized memory locations, which has unspecified impact and attack vectors.
