CVE-2014-8640: Race Condition
First published: Wed Jan 14 2015(Updated: )
The mozilla::dom::AudioParamTimeline::AudioNodeInputValue function in the Web Audio API implementation in Mozilla Firefox before 35.0 and SeaMonkey before 2.32 does not properly restrict timeline operations, which allows remote attackers to cause a denial of service (uninitialized-memory read and application crash) via crafted API calls.
