SV-64521r2_rule All manual page files must not have extended ACLs.

Vulnerability discussion

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

Check content

Verify all manual page files have no extended ACLs. # ls -lLR /usr/share/man /usr/share/info /usr/share/infopage If the permissions include a '+', the file has an extended ACL this is a finding.

Fix text

Remove the extended ACL from the file. # setfacl --remove-all /usr/share/man/* /usr/share/info/* /usr/share/infopage/*

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.
