Description Huzaifa S. Sidhpurwala 2015-12-15 08:40:29 UTC
Security researcher Looben Yang reported a use-after-free error in WebRTC that occurs due to timing issues in WebRTC when closing channels. WebRTC may still believe is has a datachannel open after another WebRTC function has closed it. This results in attempts to use the now destroyed datachannel, leading to a potentially exploitable crash.
