The fifth vulnerability appears to have been discovered internally by Google security researchers. As usual, Google is not disclosing details of the vulnerabilities in order to be able to roll out the update in waves.

The Chrome version 83.0.4103.97 for Windows, Mac and Linux will be rolled out to the systems in the next few days via the automatic update function. You can also download this build here.
