+ <title>NVIDIA binary graphics driver: Privilege escalation vulnerability</title>
+ <synopsis>
+ The NVIDIA binary graphics driver is vulnerable to a local privilege
+ escalation through an X session.
+ </synopsis>
+ <product type="ebuild">nvidia-drivers</product>
+ <announced>November 07, 2006</announced>
+ <revised>November 10, 2006: 02</revised>
+ <bug>151635</bug>
+ <access>remote, local</access>
+ <affected>
+ <package name="x11-drivers/nvidia-drivers" auto="yes" arch="*">
+ <unaffected range="ge">1.0.8776</unaffected>

+ <background>
+ <p>
+ 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.

+ <description>
+ <p>
+ Rapid7 reported a boundary error in the NVIDIA binary graphics driver
+ that leads to a buffer overflow in the accelerated rendering
+ functionality.
+ </p>
+ </description>
+ <impact type="high">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ Disable the accelerated rendering functionality in the Device section
+ of xorg.conf :
+ </p>
+ <code>Option &quot;RenderAccel&quot; &quot;false&quot;</code>
+ </workaround>
+ <resolution>
+ <p>
+ NVIDIA binary graphics driver users should upgrade to the latest
+ version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=x11-drivers/nvidia-drivers-1.0.8776&quot;</code>
+ </resolution>
