References:
    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-0021

Description:
    Previous versions of NTP do not properly check the return value from the
    OpenSSL EVP_VerifyFinal funciton, which allows remote attackers to bypass
    validation of the certificate chain via a malformed SSL/TLS signature for
    DSA and ECDSA keys.
