Provide home-made patch for legacy nVidia drivers against recent arbitrary
memory access vulnerability. While affected underlying code is very similar
in all released drivers, and they all are technically exploitable the same
way, the exploit relies on hardware that is not present in GPUs older than
NV50/G80, hence versions starting from 100.14.03 must be patched.
That said, while the patch does apply to all legacy versions, port revision
bump makes sense only for 173.14.xx series (as 96.43.xx and 71.86.xx do not
hardware exploit relies upon).
Discussed with: Christian Zander
Security: CVE-2012-0946
