Name of the Vulnerable Software and Affected Versions Valve Steam Client for Windows versions prior to 2019-08-16

Description The issue allows local users to escalate privileges to NT AUTHORITYSYSTEM. This is possible because local users can replace the current versions of SteamService.exe and SteamService.dll with older versions that lack a specific security patch.
