RHSA-2018:1605 - Security Advisory

Topic

Updated collectd packages are now available for Red Hat OpenStack Platform 10.0 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.

Description

Red Hat OpenStack Platform Operational Tools provides the facilities for monitoring a private or public Red Hat OpenStack Platform cloud.

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:

• collectd: double free in csnmp_read_table function in snmp.c (CVE-2017-16820)
