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

CrossFont 7.5 contains a buffer overflow vulnerability that allows local attackers to crash the application by submitting an oversized payload in the License Key field. Attackers can generate a malicious file containing 4000 bytes of data, paste it into the License Key input field, and trigger an application crash when processing the input.
