Descriptions

script-login in Dovecot 2.0.x before 2.0.13 does not follow the user and group configuration settings, which might allow remote authenticated users to bypass intended access restrictions by leveraging a script.

La secuencia de comandos de inicio de sesión en Dovecot v2.0.x antes de v2.0.13 no sigue la configuración del usuario y grupo, lo que podría permitir a usuarios remotos autenticados eludir las restricciones de acceso destinados al aprovechar una secuencia de comandos.
