New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote Oracle Linux host is missing a security update.

Description

From Red Hat Security Advisory 2009:0046 :

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.
(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.

Solution

Update the affected ntp package.
