SumatraPDF is a multi-format reader for Windows. In 3.5.2 and earlier, there is a Untrusted Search Path vulnerability when Advanced Options setting is trigger.

On Windows, this allows execution of a malicious notepad.exe placed in the application's installation directory, leading to arbitrary code execution.
