2. Relevant releases/architectures:

Red Hat Enterprise Linux OpenStack Platform 6.0 (Juno) for RHEL 7 - x86_64

3. Description:

Nagios is a program that monitors hosts and services on your network, and
has the ability to send email or page alerts when a problem arises or is
resolved. Nagios is written in C and designed to run under Linux (and some
other *NIX variants) as a background process, intermittently running checks
on various services that you specify. The actual service checks are
performed by separate "plugin" programs which return the status of the
checks to Nagios. Nagios plugins are available at
http://sourceforge.net/projects/nagiosplug. This package provides the core
program, web interface, and documentation files for Nagios. Development
files are built as a separate package.

Security Fix(es):

* Various command-execution flaws were found in the Snoopy library included
with Nagios. These flaws allowed remote attackers to execute arbitrary
commands by manipulating Nagios HTTP headers. (CVE-2008-7313,
CVE-2014-5008, CVE-2014-5009)

* It was found that an attacker who could control the content of an RSS
feed could execute code remotely using the Nagios web interface. This flaw
could be used to gain access to the remote system and in some scenarios
control over the system. (CVE-2016-9565)

* A privileges flaw was found in Nagios where log files were unsafely
handled. An attacker who could control Nagios logging configuration
('nagios' user/group) could exploit the flaw to elevate their access to
that of a privileged user. (CVE-2016-9566)

Red Hat would like to thank Dawid Golunski for reporting CVE-2016-9565 and
CVE-2016-9566.
