Cisco closes numerous holes in its security products
Cisco has released updates to close numerous security holes in several of its products. The ASA 5500 Adaptive Security Appliances are most affected. They alone contain six vulnerabilities that can be exploited to remotely cripple or reboot a device via specially crafted TCP, SIP, SCCP or IKE packets. Furthermore, attackers can trick its integrated NTLMv1 authentication into granting device access via manipulated user names.
