The remote Red Hat host is missing a security update.
Updated ntp packages to correct a security issue are now available for
Red Hat Enterprise Linux 4 and 5.
This update has been rated as having moderate security impact by the
Red Hat Security Response Team.
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.
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.
