Synopsis
========

Multiple vulnerabilities were discovered in Gentoo's ebuild for Zabbix
which could lead to root privilege escalation.

Background
==========

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

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/zabbix          < 4.4.6             >= 3.0.30:0/3.0
                                                      >= 4.0.18:0/4.0

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

It was discovered that Gentoo's Zabbix ebuild did not properly set
permissions or placed the pid file in an unsafe directory.

Impact
======

A local attacker could escalate privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Zabbix 3.0.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=net-analyzer/zabbix-3.0.30:0/3.0"

All Zabbix  4.0.x users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=net-analyzer/zabbix-4.0.18:0/4.0"

All other Zabbix users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-analyzer/zabbix-4.4.6"
