RHSA-2018:0299 - Security Advisory

Topic

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

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):

• A double-free vulnerability was found in the csnmp_read_table function in the SNMP plugin of collectd. A network-based attacker could exploit this by sending malformed data, causing collectd to crash or possibly other impact. (CVE-2017-16820)
