Application crash via oversized license key
Published Feb 11, 2026 · Updated Feb 11, 2026
Buffer overflow in DigitalVolcano Software TextCrawler Pro 3.1.1 allows local users to crash the application through its license key field. The activation workflow accepts a user-supplied license key without enforcing the destination buffer's size; a 6,000-byte value terminates the process. Exploitation requires local interaction with the Windows interface to paste the payload and select Activate, and the demonstrated consequence is limited to an application crash.
