Application denial of service via oversized registration key

Published Feb 2, 2024 · Updated May 15, 2025

Denial of service in MunSoft Easy Outlook Express Recovery 2.0 allows local users to interrupt the application via a crafted registration key. The Registration Key Handler accepts a 360-character string pasted into its key field and enters a denial-of-service state. Exploitation requires local low-privileged access; public sources do not distinguish a crash from a hang or report data exposure or modification.
