Security readout for executives and security teams

CVE-2011-0667 is a Windows kernel driver flaw that could let someone who can run code on an affected machine gain higher privileges. It is not described as a remote break-in by itself, but it can worsen compromise on legacy Windows systems. Exposure is mainly legacy Microsoft Windows endpoints or servers running the specific versions named in the CVE description, especially systems missing MS11-034. Modern supported Windows versions are not identified in the supplied sources. Treat this as high priority only if legacy affected Windows systems remain in use. The business issue is privilege escalation after initial access, which can turn a limited foothold into full system control. Mitigation focus: Apply Microsoft security update MS11-034 where applicable.; Inventory and retire unsupported affected Windows versions.; Restrict local code execution on remaining legacy systems..
