RHEL 4 : ntp (RHSA-2009:1040)
medium Nessus Plugin ID 38821
Synopsis
The remote Red Hat host is missing a security update.Description
An updated ntp package that fixes two security issues is now available for Red Hat Enterprise Linux 4.This update has been rated as having critical 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 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 or, potentially, execute arbitrary code with the privileges of the 'ntp' user. (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 or, potentially, execute arbitrary code with the privileges of the user running the ntpq command.
(CVE-2009-0159)
All ntp users are advised to upgrade to this updated package, which contains backported patches to resolve these issues. After installing the update, the ntpd daemon will be restarted automatically.
