The mozilla::dom::AudioEventTimeline function in the Web Audio API implementation in Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 does not properly create audio timelines, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read) via crafted API calls.
