Scientific Linux Security Update : ntp on SL4.x, SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

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.

After installing the update, the ntpd daemon will restart
