I would like to know if there are dangerous safety/security issues when a application is designed to call a command-line utility that opens a PDF file and yields some information in text files or images.
OS command injection comes to mind. If the user is able to control part of the command line (e.g. “AcroRd32.exe file.pdf”) If the attacker can control the name of the file, then you have to add strong white-list validation, so that “AcroRd32.exe file.pdf && format C: && rem .pdf” cannot be injected for example
