Technical Description

Multiple vulnerabilities have been identified in Cisco IOS, which could be exploited by remote attackers to cause a denial of service. These issues are caused by errors when processing malformed Secure Sockets Layer (SSL) packets, which could be exploited by remote attackers to crash an affected device and create a denial of service condition by sending a specially crafted "ClientHello", "ChangeCipherSpec", or "Finished" message during the SSL protocol exchange with the vulnerable device.
