    exists within the PDF viewer.

  - A use-after-free error exists when handling object linkage in PDFs.

  - An error within the 'webRequest' module can be exploited to cause
    interference with the Chrome Web Store.

  - A use-after-free error exits when handling CSS DOM objects.

  - An error within the WebP decoder can be exploited to cause a buffer
    overflow.

  - An out-of-bounds access error exists when clicking in date picker.
