Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

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.

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 ConvertDialogOptions function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unknown vectors.

Use-after-free vulnerability in the HTMLVideoElement interface in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 allows remote attackers to execute arbitrary code via crafted JavaScript code that modifies the URI table of a media element, aka ZDI-CAN-3176.

The InitTextures function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unknown vectors.
