Mozilla Firefox — свободный браузер на движке Gecko

The VertexBufferInterface::reserveVertexSpace function in libGLES in ANGLE, as used in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 on Windows, incorrectly allocates memory for shader attribute arrays, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via crafted (1) OpenGL or (2) WebGL content.

Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allow user-assisted remote attackers to bypass intended access restrictions and discover a redirect's target URL via crafted JavaScript code that executes after a drag-and-drop action of an image into a TEXTBOX element.

Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allow remote attackers to bypass CORS preflight protection mechanisms by leveraging (1) duplicate cache-key generation or (2) retrieval of a value from an incorrect HTTP Access-Control-* response header.

Race condition in the WorkerPrivate::NotifyFeatures function in Mozilla Firefox before 41.0 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) by leveraging improper interaction between shared workers and the IndexedDB implementation.

Heap-based buffer overflow in the nestegg_track_codec_data function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allows remote attackers to execute arbitrary code via a crafted header in a WebM video.

The TCP Socket API implementation in Mozilla Firefox before 41.0 mishandles array boundaries that were established with a navigator.mozTCPSocket.open method call and send method calls, which allows remote TCP servers to obtain sensitive information from process memory by reading packet data, as demonstrated by availability of this API in a Firefox OS application.

The ReadbackResultWriterD3D11::Run function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 misinterprets the return value of a function call, which might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unknown vectors.

The AnimationThread function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 uses an incorrect argument to the sscanf function, which might allow remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact via unknown vectors.

gfx/2d/DataSurfaceHelpers.cpp in Mozilla Firefox before 41.0 on Linux improperly attempts to use the Cairo library with 32-bit color-depth surface creation followed by 16-bit color-depth surface display, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) by using a CANVAS element to trigger 2D rendering.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 41.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
