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

Textpad 8.1.2 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long buffer string through the Run command interface. Attackers can paste a 5000-byte payload into the Command field via Tools > Run to trigger a buffer overflow that crashes the application.
