Descriptions

The ACL plugin in Dovecot before 1.1.4 treats negative access rights as if they are positive access rights, which allows attackers to bypass intended access restrictions.

El plugin ACL en Dovecot anterior a 1.1.4 amenaza los derechos del acceso negativo como si fueran derechos de acceso positivos, lo que permite a atacantes evitar las restricciones de acceso previstas.
