"An update for collectd is now available for Red Hat Gluster Storage
3.4 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.

collectd is a host-based system statistics collection daemon that
gathers metrics from various sources periodically, such as the
operating system, applications, log files and devices, and storage
clusters. As the daemon does not start up each time it updates files,
it has a low system footprint.

For Red Hat Gluster Storage Web Administration 3.4, collectd service
is responsible for gathering metrics from Red Hat Gluster Storage
clusters.

The updated collectd package includes the following security bug
fixes.

Security Fix(es) :

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

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

For more details about the security issue(s), including the impact, a
CVSS score, and other related information, refer to the CVE page(s)
listed in the References section.

This updated package contains a number of bug fixes and enhancements,
which are documented in detail in the Release Notes, linked in the
References.

All users of collectd are advised to upgrade to these updated
packages, which resolve these issues."
