Synopsis
=======
Icinga installs files with insecure permissions allowing root privilege
escalation.

Background
=========
Icinga is an open source computer system and network monitoring
application. It was originally created as a fork of the Nagios system
monitoring application in 2009.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/icinga          < 1.14.2                 Vulnerable!
    -------------------------------------------------------------------
     NOTE: Certain packages are still vulnerable. Users should migrate
           to another package if one is available or wait for the
           existing packages to be marked stable by their
           architecture maintainers.

Description
==========
It was discovered that Icinga's installed files have insecure
permissions, possibly allowing root privilege escalation.

Impact
=====
A local attacker could escalate privileges to root.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
Gentoo has discontinued support for Icinga. We recommend that users
unmerge Icinga:

  # emerge --unmerge "net-analyzer/icinga"

NOTE: The Gentoo developer(s) maintaining Icinga have discontinued
support at this time. It may be possible that a new Gentoo developer
will update Icinga at a later date. The natural replacement is Icinga 2
(net-analyzer/icinga2).
