A uninitialized memory use vulnerability has been found in the WebRTC component of Firefox < 60.0, which can use a WrappedI420Buffer pixel buffer whose owning image object can be freed while it is still in use. This can result in the WebRTC encoder using uninitialized memory, leading to a potentially exploitable crash.
