Descriptions

In Dovecot before 2.3.9.2, an attacker can crash a push-notification driver with a crafted email when push notifications are used, because of a NULL Pointer Dereference. The email must use a group address as either the sender or the recipient.

En Dovecot versiones anteriores a 2.3.9.2, un atacante puede bloquear un controlador de notificación push con un correo electrónico diseñado cuando notificaciones push son usadas, debido a una desreferencia del puntero NULL. El correo electrónico debe usar una dirección de grupo como remitente o destinatario.
