FreeBSD : leafnode fetchnews denial-of-service triggered by truncated transmission (a051a4ec-3aa1-4dd1-9bdc-a61eb5700153)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

When a downloaded news article ends prematurely, i. e. when the server
sends [CR]LF.[CR]LF before sending a blank line, fetchnews may wait
indefinitely for data that never arrives. Workaround: configure
'minlines=1' (or use a bigger value) in the configuration file. Found
by Toni Viemero.
