Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper neutralization of argument delimiters in a command in ev_spawn() in shell/ev-application.c when processing a crafted /GoToR action in a PDF document. A remote attacker can trick the victim into clicking a crafted link in a malicious PDF to execute arbitrary code.

User interaction is required to click a link inside the PDF document, and the issue can be delivered as a single polyglot file that is both a valid PDF and a valid ELF shared library.
