(RHSA-2017:1285) Moderate: collectd security, bug fix, and enhancement update

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.

The following packages have been upgraded to a newer upstream version: collectd (5.7.1). (BZ#1446472)

Security Fix(es):

• collectd contains an infinite loop due to how the parse_packet() and parse_part_sign_sha256() functions interact. If an instance of collectd is configured with “SecurityLevel None” and with empty “AuthFile” options an attacker can send crafted UDP packets that trigger the infinite loop, causing a denial of service.
