Descriptions

The nvcoaft51 driver in Norman Virus Control (NVC) 5.82 uses weak permissions (unrestricted write access) for the NvcOa device, which allows local users to gain privileges by (1) triggering a buffer overflow in a kernel pool via a string argument to ioctl 0xBF67201C; or by (2) sending a crafted KEVENT structure through ioctl 0xBF672028 to overwrite arbitrary memory locations.

El controlador de dispositivo nvcoaft51 de Norman Virus Control (NVC) 5.82 utiliza permisos débiles (acceso de escritura no restringido) para el dispositivo NvcOa, lo cual permite a usuarios locales obtener privilegios al (1) disparar desbordamiento de búfer en un espacio de memoria del kernel mediante un argumento tipo cadena en ioctl 0xBF67201C; ó (2) enviando una estructura KEVENT manipulada hasta ioctl 0xBF672028 para sobre-escribir posiciones de memoria de su elección.
