[HIGH] Microsoft Patch Tuesday, April 2021 Edition
Microsoft today released updates to plug at least 110 security holes in its Windows operating systems and other products. The patches include four security fixes for Microsoft Exchange Server — the same systems that have been besieged by attacks on four separate (and zero-day) bugs in the email software over the past month. Redmond also patched a Windows flaw that is actively being exploited in the wild.
Nineteen of the vulnerabilities fixed this month earned Microsoft’s most-dire “Critical” label, meaning they could be used by malware or malcontents to seize remote control over vulnerable Windows systems without any help from users.
Microsoft released updates to fix four more flaws in Exchange Server versions 2013-2019 ( CVE-2021-28480 , CVE-2021-28481 , CVE-2021-28482 , CVE-2021-28483
