VULHUB ™

The Cisco VPN Client is prone to a remotely exploitable buffer overflow condition. It is possible to trigger this condition by sending malformed IKE packets to the client. The overflow occurs when the Security Parameter Index payload of the IKE packet is longer than 16 bytes in length. It may be possible to exploit this condition to execute arbitrary code with the privileges of the client. It is possible that exploitation of this vulnerability may affect availability of the client, resulting in a denial of service condition. This issue is reported to be exploitable when the client software is operating in Aggressive Mode during a phase 1 IKE exchange. This vulnerability affects versions of the client on all platforms.
