  - A use-after-free vulnerability in the Skia library can occur when
    creating a path, leading to a potentially exploitable crash.

  - An integer overflow vulnerability in the Skia library can occur after
    specific transform operations, leading to a potentially exploitable crash

  - Cross-origin images can be read from a canvas element in violation
    of the same-origin policy using the transferFromImageBitmap method.");
