In Dovecot before 2.3.10.1, remote unauthenticated attackers can crash the lmtp or submission process by sending mail with an empty localpart.

En Dovecot versiones anteriores a 2.3.10.1, los atacantes remotos no autenticados pueden bloquear el proceso lmtp o submission mediante el envío de un correo con un localpart vacío.

Open-Xchange Dovecot versions 2.3.0 through 2.3.10 suffer from null pointer dereference and denial of service vulnerabilities.
