Description
A state confusion issue has been found in Firefox before 74 and Thunderbird before 68.6, in BodyStream::OnInputStreamReady. By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of an array resized during script execution. This could have led to memory corruption and a potentially exploitable crash.
