Recommendation: Plan a near-term fix — a public PoC already exists.

Softdisk 3.0.3 contains a buffer overflow vulnerability in the registration code dialog that allows local attackers to crash the application by supplying an oversized string. Attackers can trigger the vulnerability by entering a 6000-byte payload in the Registration Name field through the Help menu's Enter Registration Code dialog to cause a denial of service.
