Description Huzaifa S. Sidhpurwala 2016-06-06 00:14:39 EDT

Mozilla community member jomo reported a use-after-free crash when processing WebGL content. This issue was caused by the use of a texture after its recycle pool has been destroyed during WebGL operations, which frees the memory associated with the texture. This results in a potentially exploitable crash when the texture is later called.
