CVE-2009-0159 Stack-based buffer overflow in the cookedprint function
in ntpq/ntpq.c in ntpq in NTP before 4.2.4p7-RC2 allows remote NTP
servers to execute arbitrary code via a crafted response.

CVE-2009-1252 Stack-based buffer overflow in the crypto_recv function
in ntp_crypto.c in ntpd in NTP before 4.2.4p7 and 4.2.5 before
4.2.5p74, when OpenSSL and autokey are enabled, allows remote
attackers to execute arbitrary code via a crafted packet containing an
extension field.

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.
