This would matter more if PDF digital signatures were widely used. Still, the researchers have worked with the various companies that make PDF readers to close the vulnerabilities. You should update your software.

“You should update your software.”
If only that were possible without the issues and side effects.
There wasa time when PDF readers were simple and small, thus worked well on what is now considered ‘antiquated hardware and OS’ such as Windows XP running on 6 and more year old hardware with limited memory. Likewise a whole heap of ‘mobile devices’.
For many many people PDFs realy nolonger serve the purpose they were selected for. PDFs also have a history of vulnerabilities due to a number of reasons intrinsic to the file format (it is after all a form of ‘source code’ not to disimilar to Forth).
Perhaps we should br looking to replace them with something more appropriate.
