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

Vulnerability Assessment Summary
NVIDIA binary graphics driver: Privilege escalation vulnerability

Detailed Explanation for this Vulnerability Assessment
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 rights 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"
