"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2018:0299 advisory.

    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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
