Published: 2016-01-26 05:11:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:P/A:N

Detection Type:
Linux Distribution Package

Summary:
Check the version of ntp

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The Network Time Protocol (NTP) is used to synchronize a computer's time with a referenced time source. It was discovered that ntpd as a client did not correctly check the originate timestamp in received packets. A remote attacker could use this flaw to send a crafted packet to an ntpd client that would effectively disable synchronization with the server, or push arbitrary offset/delay measurements to modify the time on the client. (CVE-2015-8138) All ntp users are advised to upgrade to these updated Linux Distribution Packages, which contain a backported patch to resolve this issue. After installing the update, the ntpd daemon will restart automatically.

Affected Versions:
ntp on CentOS 6

Recommendations:
Please Install the Updated Packages.

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
