Free Download Manager 2.0 Built 417 contains a local buffer overflow vulnerability in the URL import functionality that allows attackers to trigger a structured exception handler (SEH) chain exploitation. Attackers can craft a malicious URL file that, when imported through the File > Import > Import lists of downloads menu, causes a buffer overflow in the Location header response that overwrites the SEH chain and executes arbitrary code.
