# A remote code execution vulnerability exists in "Microsoft COM for Windows" when it fails to properly handle…

Microsoft COM for Windows deserializes untrusted data without checks, so a specially crafted file or script can be used to run code. An attacker who gets this to run can escalate privileges or execute code remotely.

_Summary, check and fix written by a model from the sources; labelled as such._
