The Mozilla Foundation reports:

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