Description Huzaifa S. Sidhpurwala 2012-04-22 03:20:18 EDT
Mozilla community member Ms2ger found an image rendering issue with WebGL when texImage2D uses use JSVAL_TO_OBJECT on arbitrary objects. This can lead to a crash on a maliciously crafted web page. While there is no evidence that this is directly exploitable, there is a possibility of remote code execution.
