The vulnerability is due to incorrect processing of extremely long routing updates. An attacker could exploit this vulnerability by sending a large routing update. A successful exploit could allow the attacker to trigger inconsistency between the FIB and the RIB, resulting in a DoS condition. Cisco Bug IDs: CSCus84718."

La vulnerabilidad se debe al procesado incorrecto de actualizaciones de rutina extremadamente largas. Un atacante podría explotar esta vulnerabilidad enviando una actualización de rutina larga. Si se explota con éxito, podría permitir que el atacante cause inconsistencias entre el FIB y el RIB, provocando una denegación de servicio. Cisco Bug IDs: CSCus84718."
