Last modified

CVE-2010-5175 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. 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. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
