Race condition in ZoneAlarm Extreme Security 9.1.507.000 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 ** EN DISPUTA ** Condición de carrera en ZoneAlarm Extreme Security v9.1.507.000 sobre Windows XP permite a usuarios locales evitar kernel-mode hook handlers, y ejecutar código peligroso que podría entre otras cosas ser bloqueado por un manejador pero no bloqueado por un detector de malware signature-based, a través de ciertos user-space cambios de memoria durante la ejecución de hook-handler execution, también conocido como un ataque argument-switch o KHOBE.
