The fix for CVE-2011-4131 was not complete. Malicious NFS server could still
crash the clients when more than 2 GETATTR bitmap words are returned in
response to the FATTR4_ACL attribute request.

Sachin Prabhu (2):
  Avoid reading past buffer when calling GETACL
  Avoid beyond bounds copy while caching ACL
