Mozilla Firefox 31.7.0

Use-after-free vulnerability in the CanonicalizeXPCOMParticipant function in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 allows remote attackers to execute arbitrary code via vectors involving attachment of an XMLHttpRequest object to a shared worker.

Use-after-free vulnerability in the CanonicalizeXPCOMParticipant function in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 allows remote attackers to execute arbitrary code via vectors involving attachment of an XMLHttpRequest object to a dedicated worker.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 39.0, Firefox ESR 38.x before 38.1, and Thunderbird before 38.1 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 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Use-after-free vulnerability in the CSPService::ShouldLoad function in the microtask implementation in Mozilla Firefox before 39.0, Firefox ESR 38.x before 38.1, and Thunderbird before 38.1 allows remote attackers to execute arbitrary code by leveraging client-side JavaScript that triggers removal of a DOM object on the basis of a Content Policy.

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 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 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.

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.

The rx::d3d11::SetBufferData function in the Direct3D 11 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.

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.

PDF.js in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 enables excessive privileges for internal Workers, which might allow remote attackers to execute arbitrary code by leveraging a Same Origin Policy bypass.

The IndexedDatabaseManager class in the IndexedDB implementation in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 misinterprets an unspecified IDBDatabase field as a pointer, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors, related to a "type confusion" issue.

The AudioParamTimeline::AudioNodeInputValue function in the Web Audio implementation in Mozilla Firefox before 39.0 and Firefox ESR 38.x before 38.1 does not properly calculate an oscillator rendering range, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via unspecified vectors.

Mozilla Network Security Services (NSS) before 3.19.1, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and other products, does not properly perform Elliptical Curve Cryptography (ECC) multiplications, which makes it easier for remote attackers to spoof ECDSA signatures via unspecified vectors.

Mozilla Network Security Services (NSS) before 3.19, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, Thunderbird before 38.1, and other products, does not properly determine state transitions for the TLS state machine, which allows man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue.

Mozilla Firefox before 39.0, Firefox ESR 38.x before 38.1, and Thunderbird before 38.1 do not enforce key pinning upon encountering an X.509 certificate problem that generates a user dialog, which allows user-assisted man-in-the-middle attackers to bypass intended access restrictions by triggering a (1) expired certificate or (2) mismatched hostname for a domain with pinning enabled.
