<description>
|
|
<p>Two vulnerabilities have been discovered in NVIDIA drivers:</p>
|
|
|
|
<ul>
|
|
<li>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).
|
|
</li>
|
|
<li>A buffer overflow error has been discovered in NVIDIA drivers
|
|
(CVE-2013-0131).
|
|
</li>
|
|
</ul>
|
|
|
|
<p>NOTE: Exposure to CVE-2012-4225 is reduced in Gentoo due to 660
|
|
permissions being used on the GPU device nodes by default.
