CVE-2007-4648
Last modified
CVE-2007-4648 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.92% chance of exploitation in the next 30 days.
