The Client/Server Run-time Subsystem (aka CSRSS) in the Win32 subsystem in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, R2, and R2 SP1, and Windows 7 Gold and SP1 does not properly restrict the number of console objects for a process, which allows local users to gain privileges or cause a denial of service (memory corruption) via a crafted application that triggers an incorrect memory assignment for a user transaction, aka "CSRSS Local EOP AllocConsole Vulnerability."

Security readout for executives and security teams

This is an older Microsoft Windows local privilege escalation and denial-of-service issue in CSRSS. A logged-in local user could run a crafted application to gain higher privileges or trigger memory corruption. Business urgency depends mainly on whether legacy Windows XP, Server 2003, Vista, Server 2008, or Windows 7 systems remain in service. Exposure is likely limited to legacy Microsoft Windows versions listed in the CVE description: XP SP2/SP3, Server 2003 SP2, Vista SP1/SP2, Server 2008 variants, and Windows 7 Gold/SP1. Treat this as high priority if any listed legacy Windows systems remain operational. The issue enables local privilege escalation, which can convert ordinary footholds into administrative control. If those platforms are retired or fully patched, residual urgency is low. Mitigation focus: Follow Microsoft MS11-056 guidance and apply applicable security updates.; Retire or isolate unsupported affected Windows systems where patching is not possible.; Restrict local interactive access on affected legacy hosts..
