Buffer overflow in the rx::TextureStorage11 class in ANGLE, as used in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4, allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted texture data.

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4, when a Java plugin is enabled, allow remote attackers to cause a denial of service (incorrect garbage collection and application crash) or possibly execute arbitrary code via a crafted Java applet that deallocates an in-use JavaScript wrapper.

The CryptoKey interface implementation in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 lacks status checking, which allows attackers to have an unspecified impact via vectors related to a cryptographic key.

Integer overflow in the PL_ARENA_ALLOCATE implementation in Netscape Portable Runtime (NSPR) in Mozilla Network Security Services (NSS) before 3.19.2.1 and 3.20.x before 3.20.1, as used in Firefox before 42.0 and Firefox ESR 38.x before 38.4 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via unspecified vectors.

Race condition in the JPEGEncoder function in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) via vectors involving a CANVAS element and crafted JavaScript code.

Buffer underflow in libjar in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted ZIP archive.

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 allow remote attackers to bypass the Same Origin Policy for an IP address origin, and conduct cross-site scripting (XSS) attacks, by appending whitespace characters to an IP address string.

Heap-based buffer overflow in the ASN.1 decoder in Mozilla Network Security Services (NSS) before 3.19.2.1 and 3.20.x before 3.20.1, as used in Firefox before 42.0 and Firefox ESR 38.x before 38.4 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OCTET STRING data.

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 improperly control the ability of a web worker to create a WebSocket object, which allows remote attackers to bypass intended mixed-content restrictions via crafted JavaScript code.

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 improperly follow the CORS cross-origin request algorithm for the POST method in situations involving an unspecified Content-Type header manipulation, which allows remote attackers to bypass the Same Origin Policy by leveraging the lack of a preflight-request step.
