    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"

    References
