## Description

content/renderer/media/webrtc\_audio\_renderer.cc in Google Chrome before
24.0.1312.56 on Mac OS X does not use an appropriate buffer size for the 96
kHz sampling rate, which allows remote attackers to cause a denial of
service (memory corruption and application crash) or possibly have
unspecified other impact via a web site that provides WebRTC audio.
