Amazon Linux AMI : fail2ban Denial of Service (ALAS-2013-209)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

It was reported that fail2ban improperly parses Apache log files, due
to improper regular expressions. This could allow a remote attacker to
send a crafted URL to a web site which, when parsed by fail2ban, would
deny a specific IP address (not the remote attacker's IP).
