Red Hat Security Advisory 2018-0299-01 - collectd is a small C-language daemon, which reads various system metrics periodically and updates RRD files. Because the daemon does not start up each time it updates files, it has a low system footprint. Security Fix: 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.
