Vulnerability discussion

Excessive permissions on the aliases file may permit unauthorized modification. If the alias file is modified by an unauthorized user, they may modify the file to run malicious code or redirect e-mail.

Check content

Find the aliases file on the system. Procedure: # ls -lL /etc/mail/aliases If the aliases file exists with a mode more permissive than 0644, this is a finding.

Fix text

Change the mode of the aliases file (or equivalent) to 0644. # chmod 0644 /etc/mail/aliases

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.
