Description
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.

Check Text ( C-28701r1_chk )
Determine if the syslog daemon accepts remote messages. # ps -ef | grep syslogd If the -t option is not present, this is a finding. # grep LOG_FROM_REMOTE /etc/default/syslogd | grep -i no If the LOG_FROM_REMOTE setting is not set to no, this is a finding.

Fix Text (F-25728r1_fix)
Edit /etc/default/syslogd and set the LOG_FROM_REMOTE parameter to "no". Restart the syslog service.
