CVE-2017-7401
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.
