CVE-2017-7401

Status Candidate

Overview

Incorrect interaction of the parse_packet() and parse_part_sign_sha256() functions in network.c in collectd 5.7.1 and earlier allows remote attackers to cause a denial of service (infinite loop) of a collectd instance (configured with "SecurityLevel None" and with empty "AuthFile" options) via a crafted UDP packet.

Red Hat Security Advisory 2018-2615-01 - collectd is a host-based system statistics collection daemon that gathers metrics from various sources periodically, such as the operating system, applications, log files and devices, and storage clusters. As the daemon does not start up each time it updates files, it has a low system footprint. For Red Hat Gluster Storage Web Administration 3.4, collectd service is responsible for gathering metrics from Red Hat Gluster Storage clusters. The updated collectd package includes the following security bug fixes. Issues addressed include an infinite loop condition.

Red Hat Security Advisory 2017-1787-01 - 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. The following packages have been upgraded to a later upstream version: collectd. Security Fix: 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.
