#CVE-2017-5428: integer overflow in createImageBitmap()

Chaitin Security Research Lab via Trend Micro’s Zero Day Initiative

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.
