Code execution via Add URL stack overflow

Published Jan 28, 2026 · Updated Jan 28, 2026

Stack-based buffer overflow in VeryPDF docPrint Pro 8.0 allows local users to execute arbitrary code through the Add URL field. The doc2pdf_win.exe Add URL handler accepts an oversized pasted value that overwrites its stack and structured exception handler. Exploitation requires local GUI interaction to paste the payload and click OK, after which shellcode runs with the application's privileges.
