Welcome back to this month’s Patch Tuesday. Microsoft has published its monthly updates, fixing 77 vulnerabilities, 15 of which were rated as “Critical”. The patch also fixes two zero-day security flaws that were actively being exploited in the wild by Russian state-funded hackers. Both vulnerabilities were leveraged to elevate privileges on an already compromised system. In addition to those zero-day vulnerabilities, 6 other vulnerabilities were publicly disclosed prior to patching, but were not exploited in the wild.
