Security researcher Aral reported an out-of-bounds write when using the ANGLE graphics library, which is used for WebGL content on Windows systems. This crash occurs due to improper size checking while writing to an array during some WebGL shader operations.
The ANGLE graphics library is only used on Windows. Linux, OS X, and Android operating systems are not affected by this vulnerability.
