NVIDIA Unix security team reports :
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.
