Today is Microsoft's January 2022 Patch Tuesday, and with it comes fixes for six zero-day vulnerabilities and a total of 97 flaws.
Microsoft has fixed 97 vulnerabilities (not including 29 Microsoft Edge vulnerabilities ) with today's update, with nine classified as Critical and 88 as Important.
The number of each type of vulnerability is listed below:
- 41 Elevation of Privilege Vulnerabilities
- 9 Security Feature Bypass Vulnerabilities
- 29 Remote Code Execution Vulnerabilities
- 6 Information Disclosure Vulnerabilities
- 9 Denial of Service Vulnerabilities
- 3 Spoofing Vulnerabilities
Six zero-days fixed, none actively exploited
This month's Patch Tuesday includes fixes for six publicly disclosed zero-day vulnerabilities. The good news is that none of them have been actively exploited in attacks.
Microsoft classifies a vulnerability as a zero-day if it is publicly disclosed or actively exploited with no official fix available.
The publicly disclosed vulnerabilities fixes as part of the December 2021 Patch Tuesday are:
- CVE-2021-22947 - Open Source Curl Remote Code Execution Vulnerability
- CVE-2021-36976 - Libarchive Remote Code Execution Vulnerability
- CVE-2022-21919 - Windows User Profile Service Elevation of Privilege Vulnerability
- CVE-2022-21836 - Windows Certificate Spoofing Vulnerability
- CVE-2022-21839 - Windows Event Tracing Discretionary Access Control List Denial of Service Vulnerability
- CVE-2022-21874 - Windows Security Center API Remote Code Execution Vulnerability
Both the Curl and Libarchive vulnerabilities had already been fixed by their maintainers but the fixes were not added to Windows until today.
However, as many of these have public proof-of-concept exploits available, they will likely be exploited by threat actors soon.
Recent updates from other companies
Other vendors who released updates in January 2022 include:
- Adobe's January updates are released today.
- Android's December security updates were released last week.
- Cisco released security updates for numerous products this month, including Cisco Prime Infrastructure and Cisco Common Services Platform Collector.
- SAP released its January 2022 security updates.
