Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201304-01
(NVIDIA Drivers: Privilege escalation)

Two vulnerabilities have been discovered in NVIDIA drivers:
A vulnerability has been found in the way NVIDIA drivers handle
read/write access to GPU device nodes, allowing access to arbitrary
system memory locations (CVE-2012-4225).
A buffer overflow error has been discovered in NVIDIA drivers
(CVE-2013-0131).
NOTE: Exposure to CVE-2012-4225 is reduced in Gentoo due to 660
permissions being used on the GPU device nodes by default.

Impact :

A local attacker could gain escalated privileges.

Workaround :

There is no known workaround at this time.
