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. When an upstream NNTP server requests a header and then allows the connection to time out, the LeafNode NNTP server fails. Successful exploitation would result in a loss of availability.

Solution

Upgrade to version 1.11.3 or higher.
