  - URIs can load alternative browsers.

  - Insufficient checks on filesystem.

  - An integer overflow issue in PDFium and PDFium text rendering.

  - A compromised render can bypass site isolation.

  - Insufficient filtering of Open URL service parameters.

  - Insufficient port filtering in CORS for extensions.

  - AppCache not robust to compromised renderers.

  - Incorrect checking of click location.

  - Comparison of -0 and null yields crash.

  - Object leak of utility functions.");
