Network Time Protocol Daemon (ntpd) 4.x < 4.2.8p13 / 4.3.x < 4.3.94 DoS

high Nessus Plugin ID 122777

Language:

Synopsis

The remote NTP server is affected by a denial of service vulnerability.

Description

The version of the remote NTP server is 4.x prior to 4.2.8p13, or is 4.3.x prior to 4.3.94. It is, therefore, affected by a denial of service vulnerability due to a flaw in handling authenticated mode 6 traffic. An authenticated attacker can exploit this issue to cause application crashes.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to NTP version 4.2.8p13, 4.3.94 or later.
