Security News > 2021 > March > March 2021 Patch Tuesday forecast: Off to an early start

Microsoft got an early start on Patch Tuesday, releasing a series of out-of-band security updates this week to address four zero-day vulnerabilities in Exchange Server.

Early reports from the field indicate the updates apply smoothly following Microsoft's directions, with a reboot required.

On a final note, the next set of cumulative updates coming in March for the three versions of Exchange Server will include these security updates.

There were very few CVEs addressed in February's Patch Tuesday updates; only 28 were identified for the Windows 10 components, when we often see 50 or more.

March 2021 Patch Tuesday forecast I expect the standard fare of updates to include a larger number of CVEs fixed in the Windows 10 and legacy operating systems, Office, Microsoft 365, and the associated SharePoint server updates.

Adobe released security updates for many of their products last month and has not made any pre-announcements, so I don't expect any major updates this month.
