modules/webaudio/BiquadDSPKernel.cpp in the Web Audio API implementation in Blink, as used in Google Chrome before 37.0.2062.94, does not properly consider concurrent threads during attempts to update biquad filter coefficients, which allows remote attackers to cause a denial of service (read of uninitialized memory) via crafted API calls.
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.
