Description Huzaifa S. Sidhpurwala 2014-05-07 01:00:19 EDT

Using the Address Sanitizer tool, security researcher Abhishek Arya (Inferno) of the Google Chrome Security Team found a use-after-free in the Text Track Manager while processing HTML video. This was caused by inconsistent garbage collection of Text Track Manager variables and results in a potentially exploitable crash.
