Synopsis

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

Background

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/zabbix	< 4.4.6	>= 3.0.30	All supported architectures

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 --verbose
      ">=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 --verbose
      ">=net-analyzer/zabbix-4.0.18:0/4.0"

All other Zabbix users should upgrade to the latest version:


      # emerge --sync
