Title:RHSA-2009:0046: ntp security update (Moderate)
Description: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.
