Description:
A vulnerability has been reported in OpenBSD, which can be exploited by malicious, local users to gain escalated privileges.
The vulnerability is caused due to an input validation error in sys/dev/pci/vga_pci.c of "vga" (VGA graphics driver for wscons), which can be exploited to gain escalated privileges.
Successful exploitation may allow to gain root privileges, but requires that the kernel is compiled with "option PCIAGP" (by default only available for i386) and that the device is not AGP compatible.
The vulnerability is reported in OpenBSD 3.9 and 4.0. Other versions may also be affected.
