CVE-2010-5169: Emisoft Online Armor

High severity, CVSS 7.0. EPSS: 0.3% chance of exploitation in the next 30 days.

Race condition in Online Armor Premium 4.0.0.35 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
