The day after Patch Tuesday, when Microsoft releases fixes for security vulnerabilities across the product family, is called Exploit Wednesday. Think of it as a window, no pun intended, that is left partially open after vulnerabilities have been confirmed but before many will have installed the update. As far as the August update is concerned, that means a total of six critical issues that security experts are urging users to take note of. All of these are remote code execution vulnerabilities, meaning that the attacker does not need to have physical access to the device in order to compromise it.
