We need to force to the users do download the pdf files
And we can add to the httpd.conf or .htaccess the next code
SetEnvIf Request_URI "\.pdf$" requested_pdf=pdf
Header add Content-Disposition "Attachment" env=requested_pdf
Other solution is protect our pdf files to external links (hotlinking)
Add in .htacces
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://([-a-z0-9]+\.)?example\.com[NC]
RewriteRule .*\.(pdf)$ http://www.example.com/images/noexternal.gif [R,NC,L]

Asunto: Universal PDF XSS After Party
Everybody knows about it. Everybody talks about it. We had a nice
party. It is time for estimating the damages. In this article I will
try to show the impact of the Universal PDF XSS vulnerability by
explaining how it can be used in real life situations.
