This month we got patches for 92 vulnerabilities. Of these, 9 are critical, and 9 are zero-days (3 previously disclosed, and 6 are already being exploited).

The CVEs CVE-2024-38189, CVE-2024-38178, CVE-2024-38193, CVE-2024-38106, CVE-2024-38213, and CVE-2024-38107 are related to the already exploited vulnerabilities and the CVEs CVE-2024-38202, CVE-2024-21302, and CVE-2024-38200 are related to previously disclosed ones. 

Amongst exploited vulnerabilities, the highest CVSS (CVSS 8.8) is related to the Microsoft Project Remote Code Execution Vulnerability (CVE-2024-38189) rated as Important. According to the advisory, Exploitation requires the victim to open a malicious Microsoft Office Project file on a system where the Block macros from running in Office files from the Internet policy is disabled and VBA Macro Notification Settings are not enabled allowing the attacker to perform remote code execution.

Amongst critical vulnerabilities, one of the two 9.8 CVSS this month is associated to the Windows Reliable Multicast Transport Driver (RMCAST) Remote Code Execution Vulnerability (CVE-2024-38140). According to the exploit, this vulnerability is exploitable only if there is a program listening on a Pragmatic General Multicast (PGM) port. If PGM is installed or enabled but no programs are actively listening as a receiver, then this vulnerability is not exploitable. An unauthenticated attacker could exploit the vulnerability by sending specially crafted packets to a Windows Pragmatic General Multicast (PGM) open socket on the server, without any interaction from the user.

The other CVSS 9.8 is associated with the Windows TCP/IP Remote Code Execution Vulnerability (CVE-2024-38063). Systems are not affected if IPv6 is disabled on the target machine. The advisory says that an unauthenticated attacker could repeatedly send IPv6 packets, that include specially crafted packets, to a Windows machine which could enable remote code execution.
