medium Nessus Network Monitor Plugin ID 3011

Synopsis

The remote host is vulnerable to a Denial of Service (DoS) attack.

Description

The remote host is running the LeafNode NNTP server. The version of LeafNode that is installed is vulnerable to a remote Denial of Service (DoS) attack.

Solution

Upgrade to version 1.11.3 or higher.
