GEN005480 - The syslog daemon must not accept remote messages unless it is a syslog server documented using site-defined procedures.

Information

Unintentionally running a syslog server that accepts remote messages puts the system at increased risk. Malicious syslog messages sent to the server could exploit vulnerabilities in the server software itself, could introduce misleading information in to the system's logs, or could fill the system's storage leading to a Denial of Service.

Solution

Change the syslogd arguments in the src subsystem control and restart the syslogd daemon.
# chssys -s syslogd -a '-R'
# stopsrc -s syslogd
# startsrc -s syslogd
