NVIDIA drivers: Denial of service

Background

The NVIDIA drivers provide support for NVIDIA graphic boards.

Description

Gregory Shikhman discovered that the default Gentoo setup of NVIDIA drivers creates the /dev/nvidia* with insecure file permissions.

Impact

A local attacker could send arbitrary values into the devices, possibly resulting in hardware damage on the graphic board or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All NVIDIA drivers users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose "x11-drivers/nvidia-drivers"
