Descriptions

The message parsing feature in Dovecot 1.1.4 and 1.1.5, when using the FETCH ENVELOPE command in the IMAP client, allows remote attackers to cause a denial of service (persistent crash) via an email with a malformed From address, which triggers an assertion error, aka "invalid message address parsing bug."

La característica de análisis sintáctico en Dovecot v1.1.4 y v1.1.5, cuando usa el comando FETCH ENVELOPE en el cliente IMAP, permite a atacantes remotos causar denegación de servicio (caída persistente) a través de un correo electrónico con una dirección From mal formada, que dispara una error de aserción, también conocido como "error de análisis de dirección de mensaje inválido".
