Recommendation: Plan a near-term fix — a public PoC already exists.
Snes9K 0.0.9z contains a buffer overflow vulnerability in the Netplay Socket Port Number field that allows local attackers to trigger a structured exception handler (SEH) overwrite. Attackers can craft a malicious payload and paste it into the Socket Port Number field via the Netplay Options menu to achieve code execution through SEH chain exploitation.
