- Multiple Vulnerabilities in Cisco IOS While Processing SSL Packets
Cisco IOS devices may crash while processing malformed Secure Sockets Layer (SSL) packets. In order to trigger these vulnerabilities, a malicious client must send malformed packets during the SSL protocol exchange with the vulnerable device.<img src="http://www.cisco.com/swa/j/zag2_vs_log1.asc?Log=1&vs_f=Cisco+Security+Advisories&vs_p=Multiple+Vulnerabilities+in+Cisco+IOS+While+Processing+SSL+Packets" border="0" height="0" width="0" />
- Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers
A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. For the device to be affected by this vulnerability the device also has to have certain Internet Protocol version 4 (IPv4) User Datagram Protocol (UDP) services enabled. To exploit this vulnerability an offending IPv6 packet must be targeted to the device. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. The only exception is Resource Reservation Protocol (RSVP) service, which if exploited, will cause the device to crash. Only the interface on which the vulnerability was exploited will be affected. <img src="http://www.cisco.com/swa/j/zag2_vs_log1.asc?Log=1&vs_f=Cisco+Security+Advisories&vs_p=Cisco+IOS+User+Datagram+Protocol+Delivery+Issue+For+IPv4/IPv6+Dual-stack+Routers" border="0" height="0" width="0" />

Certain Cisco Catalyst 6500 Series and Cisco 7600 Router devices that run branches of Cisco IOS based on 12.2 can be vulnerable to a denial of service vulnerability that can prevent any traffic from entering an affected interface. For a device to be vulnerable, it must be configured for Open Shortest Path First (OSPF) Sham-Link and Multi Protocol Label Switching (MPLS) Virtual Private Networking (VPN). This vulnerability only affects Cisco Catalyst 6500 Series or Catalyst 7600 Series devices with the Supervisor Engine 32 (Sup32), Supervisor Engine 720 (Sup720) or Route Switch Processor 720 RSP720) modules. The Supervisor 32, Supervisor 720, Supervisor 720-3B, Supervisor 720-3BXL, Route Switch Processor 720, Route Switch Processor 720-3C, and Route Switch Processor 720-3CXL are all potentially vulnerable.<img src="http://www.cisco.com/swa/j/zag2_vs_log1.asc?Log=1&vs_f=Cisco+Security+Advisories&vs_p=Vulnerability+in+Cisco+IOS+with+OSPF,+MPLS+VPN,+and+Supervisor+32,+Supervisor+720,+or+Route+Switch+Processor+720" border="0" height="0" width="0" />
