RHEL 7 : collectd (RHSA-2017:1285)
Medium Nessus Plugin ID 100454
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionAn update for collectd is now available for RHEV 4.X RHEV-H and Agents for RHEL-7 and RHEV Engine version 4.1.
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 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.
SolutionUpdate the affected packages.
