Synopsis
=======
Multiple vulnerabilities have been found in Nagios, the worst of which
could lead to privilege escalation.

Background
=========
Nagios is an open source host, service and network monitoring program.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/nagios-core
                                  < 4.2.4                    >= 4.2.4

Description
==========
Multiple vulnerabilities have been discovered in Nagios. Please review
the CVE identifiers referenced below for details.

Impact
=====
A local attacker, who either is already Nagios's system user or belongs
to Nagios's group, could potentially escalate privileges.

In addition, a remote attacker could read or write to arbitrary files
by spoofing a crafted response from the Nagios RSS feed server.

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

Resolution
=========
All Nagios users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-analyzer/nagios-core-4.2.4"
