CVE-2010-5175: Pwicorp Privatefirewall

Medium severity, CVSS 4.8. EPSS: 0.3% chance of exploitation in the next 30 days.

Race condition in PrivateFirewall 7.0.20.37 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
