    overflow vulnerability in librelp, a library providing reliable event
    logging over the network, triggered while checking x509 certificates
    from a peer. A remote attacker able to connect to rsyslog can take
    advantage of this flaw for remote code execution by sending a specially
    crafted x509 certificate.
