Description Huzaifa S. Sidhpurwala 2017-03-17 04:27:21 UTC

An integer overflow in <code>createImageBitmap()</code> reported through the Pwn2Own contest. The fix for this vulnerability disables the experimental <code>createImageBitmap</code> API. This function runs in the content sandbox, requiring  a second vulnerability to compromise a user's computer.
