                   Red Hat Security Advisory

Synopsis:          Moderate: collectd security update
Advisory ID:       RHSA-2017:1787-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2017:1787

=====================================================================

1. Summary:

An update for collectd is now available for Red Hat OpenStack Platform 11.0
Operational Tools for RHEL 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 11.0 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.

The following packages have been upgraded to a later upstream version:
collectd (5.7.2). (BZ#1460080)

Security Fix(es):

* collectd contains an infinite loop due to how the parse_packet() and
parse_part_sign_sha256() functions interact. If an instance of collectd is
configured with "SecurityLevel None" and empty "AuthFile" options, an
attacker can send crafted UDP packets that trigger the infinite loop,
causing a denial of service. (CVE-2017-7401)

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/):

1439674 - CVE-2017-7401 collectd: Infinite loop due to incorrect interaction of parse_packet() and parse_part_sign_sha256() functions
