Description Huzaifa S. Sidhpurwala 2012-04-22 06:50:22 UTC
Mozilla community member Matias Juntunen discovered an error in WebGLBuffer where FindMaxElementInSubArray receives wrong template arguments from FindMaxUshortElement. This bug causes maximum index to be computed incorrectly within WebGL.drawElements, allowing the reading of illegal video memory.
