The mozilla::dom::AudioBufferSourceNodeEngine::CopyFromInputBuffer function in Mozilla Firefox before 31.0 and Thunderbird before 31.0 does not properly allocate Web Audio buffer memory, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via crafted audio content that is improperly handled during playback buffering.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
