CVE-2010-5173: Race Condition
First published: Sat Aug 25 2012(Updated: )
** DISPUTED ** Race condition in PC Tools Firewall Plus 6.0.0.88 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.
