  687 
  688       o Security fix: change behavior of OpenSSL to avoid using
  689         environment variables when running as root.
  690       o Security fix: check the result of RSA-CRT to reduce the
  691         possibility of deducing the private key from an incorrectly
  692         calculated signature.
