/doc shows the content of the /usr/doc directory and therefore it shows which programs and - important! - the version of the installed programs.

Solution : Use access restrictions for the /doc directory.
If you use Apache you might use this in your access.conf:

 <Directory /usr/doc>
 AllowOverride None
 order deny,allow
 deny from all
 allow from localhost
 </Directory>

Risk factor : High";
