Descriptions

A vulnerability in the crypto engine of the Cisco Integrated Services Module for VPN (ISM-VPN) running Cisco IOS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient handling of VPN traffic by the affected device. An attacker could exploit this vulnerability by sending crafted VPN traffic to an affected device. A successful exploit could allow the attacker to cause the affected device to hang or crash, resulting in a DoS condition. Cisco Bug IDs: CSCvd39267.

Una vulnerabilidad en el motor criptográfico del módulo Cisco Integrated Services Module for VPN (ISM-VPN) que ejecute Cisco IOS Software podría permitir que un atacante remoto sin autenticar provoque una denegación de servicio (DoS) en un sistema afectado. Esta vulnerabilidad se debe a una gestión insuficiente de tráfico VPN por parte de un dispositivo afectado. Un atacante podría explotar esta vulnerabilidad enviando trafico VPN manipulado a un dispositivo afectado. Si se explota con éxito, esta situación podría permitir que el atacante consiga que el dispositivo se bloquee o se cierre de manera inesperada, lo que daría como resultado una denegación de servicio (DoS). Cisco Bug IDs: CSCvd39267.
