  A buffer overflow flaw was discovered in the ntpd daemon's NTPv4
  authentication code. If ntpd was configured to use public key cryptography
  for NTP packet authentication, a remote attacker could use this flaw to
  send a specially-crafted request packet that could crash ntpd.
  (CVE-2009-1252)

  Note: NTP authentication is not enabled by default.

  A buffer overflow flaw was found in the ntpq diagnostic command. A
  malicious, remote server could send a specially-crafted reply to an ntpq
  request that could crash ntpq. (CVE-2009-0159)

  All ntp users are advised to upgrade to this updated package, which
  contains backported patches to resolve these issues. After installing the
