Don’t rely on the luck of the Irish when comes to protecting your cybersecurity environment. Pay attention to this month’s, Microsoft Patch Tuesday announcement. This month, Microsoft announced patches for 80 new vulnerabilities, including 9 that Microsoft has rated critical, and 2 zero-day (CVE-2023-23397, CVE-2023-24880). This release also included updates to 4 previously released CVEs and one Advisory.

Of the 80 new vulnerabilities, 67 have Knowledgebase (KB) fixes, 9 have release notes associated with them and 4 have updates required from the Microsoft Appstore.

The headline issues this month are once again the known exploitable zero-day CVEs:

  • CVE-2023-23397 – Microsoft Outlook Elevation of Privilege Vulnerability
  • CVE-2023-24880 – Windows SmartScreen Security Feature Bypass Vulnerability

Breaking down the 80 vulnerabilities further, we can see that remote code execution and elevation of privileges lead the way again this month in terms of impact type.
