## Description

The mozilla::AudioSink function in Mozilla Firefox before 40.0 and Firefox
ESR 38.x before 38.2 mishandles inconsistent sample formats within MP3
audio data, which allows remote attackers to execute arbitrary code or
cause a denial of service (out-of-bounds read) via a malformed file.
