tag_insight = "The Network Time Protocol (NTP) is used to synchronize a computer's time
  with a referenced time source.

  A flaw was discovered in the way the ntpd daemon checked the return value
  of the OpenSSL EVP_VerifyFinal function. On systems using NTPv4
  authentication, this could lead to an incorrect verification of
  cryptographic signatures, allowing time-spoofing attacks. (CVE-2009-0021)
  
  Note: This issue only affects systems that have enabled NTP authentication.
  By default, NTP authentication is not enabled.
  
  All ntp users are advised to upgrade to the updated packages, which contain
  a backported patch to resolve this issue. After installing the update, the
  ntpd daemon will restart automatically.";
