Microsoft addressed 56 security vulnerabilities for February Patch Tuesday, including 11 critical and six publicly known bugs. The computing giant continued to address the Zerologon bug, which is being actively exploited in the wild. Six of the security holes including one of the critical bugs were already publicly disclosed. None of the bugs rate more than an 8.8 (out of 10) on the CVSS scale, but all allow for remote code execution (RCE) and many should take top priority.
