Vigil@nce - FreeBSD: privilege escalation via NVIDIA Kernel Driver
September 2015 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can use the NVIDIA driver on FreeBSD, in order to
escalate his privileges.
Impacted products: FreeBSD.
Severity: 2/4.
Creation date: 20/07/2015.
DESCRIPTION OF THE VULNERABILITY
The NVIDIA (nvidia.ko) graphic driver can be installed on FreeBSD.
An /dev/nvidia* device is used to communicate with user space.
However, a user can chose the value of a pointer, in order to read
or write in kernel memory.
An attacker can therefore use the NVIDIA driver on FreeBSD, in
order to escalate his privileges.
