OpenBSD-projektet har offentliggjort en b\u00e6rbar udgave af LibreSSL-pakken 3.2.5, som udvikler en fork af OpenSSL med det form\u00e5l at sikre et h\u00f8jere sikkerhedsniveau. I den nye version er der rettet en fejl i implementeringen af TLS-klienten, som f\u00f8rte til adgang til et allerede frigivet hukommelsesblok (use-after-free) under udf\u00f8relsen af genoptagelse af session. OpenBSD's udviklere har anerkendt, at fejlen medf\u00f8rer en s\u00e5rbarhed, men har undladt at offentligg\u00f8re detaljer, idet de kun har givet en patch. Der er i \u00f8jeblikket ingen oplysninger om muligheden for at organisere et fjernangreb. Det er ikke umuligt, at s\u00e5rbarheden er relateret til det problem, der f\u00f8rte til nedbrud og blev advaret om af udviklerne af haproxy i februar.
