SV-99193r1_rule The SMTP service log file must have mode 0644 or less permissive.

Vulnerability discussion

If the SMTP service log file is more permissive than 0644, unauthorized users may be allowed to change the log file.

Check content

Check the permissions on the mail log files: # ls -la /var/log/mail # ls -la /var/log/mail.info # ls -la /var/log/mail.warn # ls -la /var/log/mail.err If the log file permissions are greater than "0644", this is a finding.

Fix text

Change the mode of the sendmail log files to "0644": # chmod 0644

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
