CVE-2019-25565Public exploit

Application crash via oversized registration serial code

Published Mar 21, 2026 · Updated Mar 21, 2026

Buffer overflow in Magic ISO Maker 5.5 build 281 allows local users to crash the application through an oversized registration serial code. The Serial Code field accepts a 5,000-byte string without enforcing the destination buffer bounds, causing an out-of-bounds write. Exploitation requires local access to the Windows GUI and submission through Register, and the demonstrated consequence is an application crash only.
