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

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

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)

After installing the update, the ntpd daemon will be restarted
automatically.
