Apple Mac OS X Safari vulnerable to arbitrary command execution via URLs in PDF files

Overview

Apple Mac OS X WebKit and Safari security controls may be bypassed, possibly allowing remote command execution.

Description

Mac OS X includes the Safari web browser, which can display Portable Document Format (PDF) files directly. This functionality is part of the WebKit system framework. The PDF rendering code in Safari is able to call the URLs directly rather than through the Safari browser. This may allow some security controls defined in Safari to be bypassed, leading to possible arbitrary command execution.

---

Impact

A remote, unauthenticated attacker may be able to persuade a user to click on a PDF file link within Safari, leading to remote command execution.
