Descriptions

plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving more specific entries that occur after less specific entries, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox.

plugins/acl/acl-backend-vfile.c en Dovecot v1.2.x anterior a v1.2.15 y v2.0.x anterior a 2.0.5 interpreta una entrada ACL como una directiva a añadir a los permisos concedidos por otra entrada ACL, en ciertas circunstancias involucrando entradas más específicas que tienen lugar después de entradas menos específicas, lo que permite a usuarios autenticados remotamente evitar restricciones de acceso intencionadas a través de una petición para leer o modificar un buzón de correo.
