CVE-2009-3623 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3623):
  The lookup_cb_cred function in fs/nfsd/nfs4callback.c in the nfsd4
  subsystem in the Linux kernel before 2.6.31.2 attempts to access a
  credentials cache even when a client specifies the AUTH_NULL
  authentication flavor, which allows remote attackers to cause a
  denial of service (NULL pointer dereference and system crash) via an
  NFSv4 mount request.
