+	  <p>When the NVIDIA driver for the X Window System is operated in
+	     "NoScanout" mode, and an X client installs an ARGB cursor that
+	     is larger than the expected size (64x64 or 256x256, depending on
+	     the driver version), the driver will overflow a buffer.  This
+	     can cause a denial of service (e.g., an X server segmentation
+	     fault), or could be exploited to achieve arbitrary code
+	     execution.  Because the X server runs as setuid root in many
+	     configurations, an attacker could potentially use this
+	     vulnerability in those configurations to gain root privileges.</p>
