Summary
The affected software is VMware vCenter Server, a tool used to manage virtualized computing environments. An attacker who can reach the server over the network could send a specially crafted packet that exploits a memory flaw in its DCERPC handling, potentially allowing them to run arbitrary code on the system.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.

Questions about CVE-2024-38812
What does this mean?
This is a heap overflow, meaning memory outside the intended buffer on the heap can be written to. The impact is potentially remote code execution on vCenter Server.Source: support.broadcom.com
Am I affected, and how do I check?
The response matrix lists VMware vCenter Server 8.0 before 8.0 U3b and 7.0 before 7.0 U3s. VMware Cloud Foundation 5.x, 5.1.x and 4.x is also listed, but no fixed version is given for it. To check, compare the installed vCenter Server version against these ranges.Source: support.broadcom.com
What should I do about it?
Upgrade vCenter Server to 8.0 U3b or 7.0 U3s, the fixed versions listed in the facts.Source: support.broadcom.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-11-20, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
