Vulnerability discussion

If Sendmail is not configured to log at level 9, system logs may not contain the information necessary for tracking unauthorized use of the sendmail service.

Check content

Check sendmail to determine if the logging level is set to level "9": # grep "O L" /etc/sendmail.cf OR # grep LogLevel /etc/sendmail.cf If logging is set to less than "9", this is a finding.

Fix text

Edit the "sendmail.cf" file, locate the "O L" or "LogLevel" entry, and change it to "9".

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.
