First published: Thu Jan 14 2010(Updated: )
Description of problem: This is similar to NTP security flaw <a href="https://access.redhat.com/security/cve/CVE-2009-3563">CVE-2009-3563</a>. chronyd replies to all cmdmon packets from unauthorized hosts with NOHOSTACCESS message. This can be used to create a loop between two chrony daemons which don't allow cmdmon access from each other by sending a packet with spoofed source address and port. This will cause high CPU, network and syslog usage. The applies to all chrony versions including 1.24-pre1.
