Race condition in F-Secure Internet Security 2010 10.00 build 246 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 is a legacy endpoint-protection bypass affecting F-Secure Internet Security 2010 10.00 build 246 on Windows XP. A local program already running on the machine could potentially evade a kernel-hook protection check. It is not described as a remote compromise, and the issue is disputed by some third parties. Exposure appears limited to legacy Windows XP endpoints running F-Secure Internet Security 2010 10.00 build 246. The source bundle does not identify broader supported products, modern versions, network services, or server-side exposure. Treat this as a legacy risk-management issue, not an internet-wide emergency. Priority is highest if Windows XP systems with this exact F-Secure build still protect sensitive business processes or regulated data. Mitigation focus: Inventory endpoints for Windows XP and F-Secure Internet Security 2010 build 246.; Check F-Secure guidance for any vendor-confirmed fix or upgrade path.; Retire unsupported Windows XP systems where possible..
