Update Information:

This update fixes CVE-2009-0021:    NTP 4.2.4 before 4.2.4p5 and 4.2.5 before
4.2.5p150 does not properly check the return value from the OpenSSL
EVP_VerifyFinal function, which allows remote attackers to bypass validation of
the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys,
a similar vulnerability to CVE-2008-5077.
