Synopsis
========
The NVIDIA binary graphics driver is vulnerable to a local privilege
escalation through an X session.
Background
==========
The NVIDIA binary graphics driver from NVIDIA Corporation provides the
kernel module and the GL modules for graphic acceleration on the NVIDIA
based graphic cards.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-drivers/nvidia-drivers lt; 1.0.8776 gt;= 1.0.8776
lt; 1.0-8762
Description
===========
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"
Resolution
==========
NVIDIA binary graphics driver users should upgrade to the latest
version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=x11-drivers/nvidia-drivers-1.0.8776"
References
==========
