Patches were also made available for older versions of Windows (versions 7 and 8.1).

The Critical RCE patches and advisories are summarized below:

  1. CVE-2022-21840: Microsoft Office RCE Vulnerability
  2. CVE-2022-21846: Microsoft Exchange Server RCE Vulnerability
  3. CVE-2022-21898: DirectX Graphics Kernel RCE Vulnerability

  7. CVE-2021-22947: Open Source Curl RCE Vulnerability
  8. CVE-2021-44228: Apache Log4j RCE Vulnerability

As readers may know, researchers had discovered a Critical 0-day vulnerability (CVE-2021-44228) in Apache Log4j “Log4Shell” logging utility under active attack last month.

“Certain versions of Apache Log4j2 are vulnerable to a remote code execution vulnerability. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled,” Microsoft noted in the advisory.

Critical Elevation of Privilege vulnerabilities

Moreover, Microsoft addressed two Critical elevation of privilege vulnerabilities that affect Virtual Machine IDE Drive (CVE-2022-21833) and Active Directory Domain Services (CVE-2022-21857).

Microsoft warned the latter update “resolves an elevation of privilege vulnerability specific to Active Directory Domain Services environments with incoming trusts.” That issue has a CVSS base score of 8.8.

Other security updates

In addition to the Critical RCEs and zero-day fixes, Microsoft also patched an additional 92 other vulnerabilities across multiple products rated “Important.” The tech giant also addressed 24 Microsoft Edge (Chromium-based) vulnerabilities.
