RHSA-2017:1787 - Security Advisory

Topic

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

The following packages have been upgraded to a later upstream version: collectd (5.7.2). (BZ#1460080)

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 empty "AuthFile" options, an attacker can send crafted UDP packets that trigger the infinite loop, causing a denial of service. (CVE-2017-7401)
