Descriptions

The SSLVPN implementation in Cisco IOS 12.4, 15.0, 15.1, and 15.2, when DTLS is not enabled, does not properly handle certain outbound ACL configurations, which allows remote authenticated users to cause a denial of service (device crash) via a session involving a PPP over ATM (PPPoA) interface, aka Bug ID CSCte41827.

La implementación de SSLVPN en Cisco IOS v12.4, v15.0, v15.1, y v15.2, cuando DTLS no está habilitado, no controla correctamente ciertas configuraciones de las listas de control de acceso ACL, lo que permite a usuarios remotos autenticados causar una denegación de servicio (caída de dispositivo) a través de una sesión que implica al interfase PPP sobre ATM (PPPoA), también conocido como Bug ID CSCte41827.
