Descriptions

A vulnerability in the peer-to-peer message processing functionality of Cisco Packet Data Network Gateway could allow an unauthenticated, remote attacker to cause the Session Manager (SESSMGR) process on an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect validation of peer-to-peer packet headers. An attacker could exploit this vulnerability by sending a crafted peer-to-peer packet through an affected device. A successful exploit could allow the attacker to cause the SESSMGR process on the affected device to restart unexpectedly, which could briefly impact traffic while the SESSMGR process restarts and result in a DoS condition. Cisco Bug IDs: CSCvg88786.

Una vulnerabilidad en la característica de procesamiento de mensajes peer-to-peer de Cisco Packet Data Network Gateway podría permitir que un atacante remoto no autenticado haga que el proceso SESSMGR (Session Manager) en un sistema afectado se reinicie. Esto resulta en una condición de denegación de servicio (DoS). Esta vulnerabilidad se debe a la validación incorrecta de cabeceras de paquetes peer-to-peer. Un atacante podría explotar esta vulnerabilidad enviando un paquete peer-to-peer manipulado mediante el dispositivo afectado. Si se explota con éxito, esta vulnerabilidad podría permitir que el atacante provoque que el proceso SESSMGR se reinicie de forma inesperada en el dispositivo afectado, lo que podría impactar brevemente al tráfico mientras el proceso SESSMGR se reinicia y desembocar en una condición de denegación de servicio (DoS). Cisco Bug IDs: CSCvg88786.
