Vigil@nce - NVIDIA UNIX Driver: privilege elevation
August 2012 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can use the NVIDIA UNIX driver, in order to write
in memory, so he can gain kernel privileges.
Severity: 2/4
Creation date: 01/08/2012
IMPACTED PRODUCTS
– Unix - plateform
DESCRIPTION OF THE VULNERABILITY
The NVIDIA UNIX driver is used by NVIDIA devices on Linux, Solaris
and FreeBSD.
The local user can access to /dev/nvidia0, in order to use the
screen. However, he can move the memory area associated to the VGA
screen, and freely write in kernel memory.
A local attacker can therefore use the NVIDIA UNIX driver, in
order to write in memory, so he can gain kernel privileges.
