The AudioParamTimeline::AudioNodeInputValue function in the Web Audio implementation in Mozilla Firefox before 39.0 and Firefox ESR 38.x before 38.1 does not properly calculate an oscillator rendering range, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via unspecified vectors.
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.
