security issue in pdf means the pdf itself have to be forged?
No, there are many other things. For instance, a PDF can start an external program...
what I mean is that you have to open a dangerous pdf to be at fault. Nobody will run your viewer per se. So as long as you use officla pdfs (nots the ones found on any unknown site) you are pretty safe.
It's very unlikely that the Canon web site hold manual with linux exploit :-)
Hardly :-) But you can be sent PDF by a friend, who has a virus, unknown to him, which alters PDFs with a certain javscript payload... ...which in Linux would do nothing. AFAIK, no Linux pdf reader supports javascript (which is one of the reasons PDF Forms do not fully work). (if you view them in foxit or acroread, then security IS a concern) But there are others exploits that I don't know about. I'm not an expert on that. -- Cheers / Saludos, Carlos E. R.
