Vulnerability discussion

Excessive permissions on files executed through a mail alias file could result in modification by an unauthorized user, execution of malicious code, and/or system compromise.

Check content

Examine the contents of the /etc/mail/aliases file. For each file referenced, check the permissions of the file. # ls -lL [file referenced from aliases] If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix text

Remove the extended ACL from the file. # chmod A- [file referenced from 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.
