NVIDIA drivers: Denial of Service

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
x11-drivers/nvidia-drivers	= 100.14.06	>= 71.86.01, revision >= 1.0.7185, revision >= 1.0.9639	All supported architectures

Related bugreports: #183567

A vulnerability has been discovered in the NVIDIA graphic drivers, allowing for a Denial of Service.

2. Impact Information

The NVIDIA drivers provide support for NVIDIA graphic boards.

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

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

3. Resolution Information

There is no known workaround at this time.

All NVIDIA drivers users should upgrade to the latest version:

Code Listing 3.1: Resolution

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