Vulnerability discussion

If manual pages are compromised, misleading information could be inserted, causing actions to compromise the system.

Check content

Check the mode of the manual page files. Procedure: # find /usr/share/man /usr/share/info /usr/share/infopage -type f -perm +022 -exec stat -c %a:%n {} \; |> more Note: This list only displays manual files with offending permissions. If any of the manual page files have a mode more permissive than 0644, this is a finding.

Fix text

Change the mode of manual page files to 0644 or less permissive. Procedure (example): # chmod 0644 /path/to/manpage

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.
