Description Huzaifa S. Sidhpurwala 2013-01-04 00:24:16 EST

Security researcher miaubiz used the Address Sanitizer tool to discover a buffer overflow in Canvas when specific bad height and width values were given through HTML. This could lead to a potentially exploitable crash.

Miaubiz also found a potentially exploitable crash when 2D and 3D content was mixed which was introduced during Firefox development and fixed before general release.
