CVE-2011-0675: Use-after-free vulnerability in win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3,...

Security readout for executives and security teams

CVE-2011-0675 is a Windows kernel privilege-escalation flaw in win32k.sys. An attacker already able to run a crafted local application could gain higher privileges. The sources identify old Windows client and server versions, so urgency depends on whether legacy Windows systems remain in the environment. Exposure is most likely on legacy Windows endpoints or servers that match the affected versions and have not received the MS11-034 update. Modern supported Windows versions are not listed in the provided affected set. Treat this as high priority only where affected legacy Windows systems still exist. It is not described as remotely exploitable, but it can turn a limited foothold into privileged control on vulnerable hosts. Mitigation focus: Apply Microsoft MS11-034 security updates where available.; Retire, isolate, or tightly restrict unsupported affected Windows systems.; Limit who can execute local applications on legacy Windows hosts..
