Microsoft has released its regularly scheduled March Patch Tuesday updates, which address 89 security vulnerabilities overall.

Included in the slew are 14 critical flaws and 75 important-severity flaws.

Four of the actively exploited flaws, found in Microsoft Exchange, were disclosed as part of an emergency patch earlier this month by Microsoft; businesses have been scrambling to patch their systems as the bugs continue to be exploited in targeted attacks.

In addition to the five actively exploited vulnerabilities, Microsoft issued a patch for a vulnerability in Win32K for which public PoC exploit code is also available.

Microsoft patched 14 critical vulnerabilities overall in this month's Patch Tuesday updates, including, which exists in Windows DNS server and can enable remote code execution.

The Microsoft Patch Tuesday updates come as businesses grapple with existing Microsoft Exchange zero-day vulnerabilities that were previously disclosed and continue to be used in active exploits.
