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.

Security readout for executives and security teams

This is an old Google Chrome for Mac issue where a malicious website using WebRTC audio could crash the browser because Chrome used the wrong buffer size for 96 kHz audio. The sources describe denial of service and possible unspecified further impact, but provide no evidence of active exploitation. Exposure is mainly legacy macOS systems running Chrome earlier than 24.0.1312.56, or embedded Chromium builds carrying the same WebRTC audio code. Current managed Chrome fleets are unlikely to be exposed if normal browser updates are enforced. Treat this as a legacy hygiene issue unless your environment still runs obsolete Chrome or embedded Chromium on macOS. It is not listed as KEV, and the known business impact is browser crash risk from web content. Mitigation focus: Upgrade Chrome on Mac OS X to 24.0.1312.56 or later.; Retire unsupported Chrome or Chromium builds in managed macOS environments.; Check embedded Chromium products for inherited WebRTC audio renderer code..
