GLSA-200611-03 : NVIDIA binary graphics driver: Privilege escalation vulnerability

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


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-200611-03
(NVIDIA binary graphics driver: Privilege escalation vulnerability)

Rapid7 reported a boundary error in the NVIDIA binary graphics driver
that leads to a buffer overflow in the accelerated rendering
functionality.

Impact :

An X client could trigger the buffer overflow with a maliciously
crafted series of glyphs. A remote attacker could also entice a user to
open a specially crafted web page, document or X client that will
trigger the buffer overflow. This could result in the execution of
arbitrary code with root privileges or at least in the crash of the X
server.

Workaround :

Disable the accelerated rendering functionality in the Device section
of xorg.conf :
Option 'RenderAccel' 'false'
