Recommendation: Monitor — no exploitation signal at the moment.

An unauthenticated remote attacker can repeatedly send a single crafted connection request to leak memory. Against storescp in its default single-process mode, memory grows quickly and the service is eventually killed, after which it stops accepting connections until an operator restarts it.
