Microsoft Patches 71 Flaws Including Exploited Windows CLFS Zero-Day
Microsoft released fixes for 71 CVEs across 10 product families, including 17 Critical and 54 Important vulnerabilities, with the update heavily concentrated on Windows. The most severe issue was CVE-2024-49112, a CVSS 9.8 remote code execution flaw in LDAP affecting supported Windows client and server versions back to Windows Server 2008, while multiple other patches addressed remote code execution risks in Remote Desktop Services and additional Windows components.
Microsoft also fixed an actively exploited zero-day, CVE-2024-49138, in the Windows Common Log File System Driver (CLFS), and identified six more vulnerabilities as more likely to be exploited within 30 days. Those higher-risk issues affected SharePoint, MSMQ, ReFS, and several Windows drivers, underscoring broad exposure across enterprise environments; Sophos said protections were available for five of the patched vulnerabilities, and noted Microsoft patched 1,015 CVEs through Patch Tuesday during 2024, the company’s highest annual total since 2020.
