Does PDF level compression implicitly cleans file of malware?
Recently I've been looking into PDF files security, specifically about malware exploiting vulnerabilities in PDF readers. I thought about one thing - does compressing PDF file (for example, by using qpdf) create as to speak "new" file (assuming it was infected before with JS, pdf viewer exploits etc) clean of these problems? Im asking because while Im somewhat aware creating new file (with Ghostscript for example) most likely would do that, but never really found out about simple compression of said file (GS doesn't do that as far as I know).
