Debian DSA-1702-1 : ntp - interpretation conflict

medium Nessus Plugin ID 35365
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

It has been discovered that NTP, an implementation of the Network Time Protocol, does not properly check the result of an OpenSSL function for verifying cryptographic signatures, which may ultimately lead to the acceptance of unauthenticated time information. (Note that cryptographic authentication of time servers is often not enabled in the first place.)

Solution

Upgrade the ntp package.

For the stable distribution (etch), this problem has been fixed in version 4.2.2.p4+dfsg-2etch1.
