Vulnerability discussion

If a file executed through a mail alias file has permissions greater than 0755, it can be modified by an unauthorized user and may contain malicious code or instructions that could compromise the system.

Check content

Examine the contents of the "/etc/aliases" file: # more /etc/aliases Examine the aliases file for any directories or paths that may be utilized: # ls -lL Check the permissions for any paths referenced. If any file referenced from the aliases file has a mode more permissive than "0755", this is a finding.

Fix text

Use the chmod command to change the access permissions for files executed from the alias file: # chmod 0755

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.
