Description Huzaifa S. Sidhpurwala 2015-11-03 00:54:43 EST

Security researcher Looben Yang reported a buffer overflow in the JPEGEncoder function during script interactions with a canvas element. This is caused by a race condition and incorrectly matched sizes following image interactions. This leads to a potentially exploitable crash.
