Microsoft stated that putting in the most recent update “stops the attack chain” primary to the distant code execution bug.
The other protection-in-depth update for the Memory Integrity Technique Readiness scan software, which is used to examine for compatibility issues with memory integrity (aka hypervisor-protected code integrity or HVCI), can take treatment of a publicly acknowledged bug whereby the “original version was published without a RSRC portion, which includes resource info for a module.”

“This suggests the attacker demands to be connected to your inside network and be capable to authenticate as a legitimate Exchange person prior to they can exploit these vulnerabilities. Any person who achieves this can carry out remote code execution making use of a PowerShell remoting session.”
Microsoft even further acknowledged the availability of a proof-of-concept (PoC) exploit for a DoS vulnerability in .NET and Visible Studio (CVE-2023-38180, CVSS score: 7.5), noting that the “code or method is not useful in all conditions and may possibly involve significant modification by a competent attacker.”
