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

# 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"
