F5 Networks BIG-IP : NTP vulnerability (SOL16392)

medium Nessus Plugin ID 85949
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 device is missing a vendor-supplied security patch.

Description

The vallen packet value is not validated in several code paths in ntp_crypto.c which can lead to information leakage or a possible crash of ntpd.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL16392.
