                   Red Hat Security Advisory

Synopsis:          Moderate: collectd security update
Advisory ID:       RHSA-2018:0252-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:0252
Issue date:        2018-01-30
CVE Names:         CVE-2017-16820 
=====================================================================

1. Summary:

An update for collectd is now available for Red Hat OpenStack Platform 12.0
Operational Tools for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenStack Platform 12.0 Operational Tools for RHEL 7 - x86_64

3. Description:

collectd is a small C-language daemon, which reads various system metrics
periodically and updates RRD files (creating them if necessary). Because
the daemon does not start up each time it updates files, it has a low
system footprint.

Security Fix(es):

* The csnmp_read_table function in the SNMP plugin of collectd, before
version 5.6.3, is susceptible to a double free in a certain error case.
This could lead to a crash. (CVE-2017-16820)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1516447 - CVE-2017-16820 collectd: double free in csnmp_read_table function in 
	  snmp.c
