Synopsis
========

A vulnerability in Zabbix could allow remote attackers to execute
arbitrary shell code.

Background
==========

Zabbix is software for monitoring applications, networks, and servers.

Affected packages
=================

                                                         *>= 2.0.9-r1

Description
===========

If a flexible user parameter is configured in Zabbix agent, including a
newline in the parameters will execute newline section as a separate
command even if UnsafeUserParameters are disabled.

Impact

privileges of the process.

Workaround
