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

medium Nessus Plugin ID 60526

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.
(CVE-2009-0021)

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 automatically.

Solution

Update the affected ntp package.
