Heap-based buffer overflow in the stagefright::SampleTable::parseSampleCencInfo function in libstagefright in Mozilla Firefox before 46.0, Firefox ESR 38.x before 38.8, and Firefox ESR 45.x before 45.1 allows remote attackers to execute arbitrary code via crafted CENC offsets that lead to mismanagement of the sizes table.

The watch implementation in the JavaScript engine in Mozilla Firefox before 46.0, Firefox ESR 38.x before 38.8, and Firefox ESR 45.x before 45.1 allows remote attackers to execute arbitrary code or cause a denial of service (generation-count overflow, out-of-bounds HashMap write access, and application crash) via a crafted web site.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 46.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
