CVE-2010-5151: Race condition in avast!

Race condition in avast! Internet Security 5.0.462 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute

Security readout for executives and security teams

This CVE describes a bypass of a security product’s behavior-blocking layer, not a remote break-in. A local program already running on Windows XP could race avast! Internet Security 5.0.462 and avoid kernel hook checks that might otherwise block dangerous behavior. Exposure appears limited to legacy Windows XP systems running avast! Internet Security 5.0.462. The bundle’s affected-product metadata is incomplete, but the CVE description names this product and version. Modern supported endpoints are unlikely to match this exact exposure unless old software remains deployed. Treat this as a legacy-risk cleanup item, not an emergency internet-wide exposure. Priority rises if regulated, production, or sensitive Windows XP assets still rely on old endpoint protection as a primary control. Mitigation focus: Inventory Windows XP endpoints and avast! Internet Security 5.0.462 installations.; Check Avast/vendor guidance for historical fixes or support statements.; Replace unsupported Windows XP systems where operationally feasible..
