Description
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.
