Descriptions

Cyrus IMAP before 3.2.7, and 3.3.x and 3.4.x before 3.4.1, allows remote authenticated users to bypass intended access restrictions on server annotations and consequently cause replication to stall.

Cyrus IMAP versiones anteriores a 3.2.7, y versiones 3.3.x y versiones 3.4.x anteriores a 3.4.1, permite a usuarios autenticados remotos omitir las restricciones de acceso previstas en las anotaciones del servidor y, en consecuencia, provocar que la replicación se detenga
