Who is Vulnerable?
Vulnerability Description	There is a vulnerability within several ISS security products, including BlackICE, RealSecure, and Proventia, in the way they parse the ICQ messaging protocol. An attacker, exploiting this vulnerability, can cause a buffer overflow, resulting in the termination of a service or execution of arbitrary code. The affected service on the target machine may terminate when receiving the malformed ICQ server response message. However, if the message involved in the attack is crafted carefully, it is possible for the attacker to inject and execute arbitrary code on the target. The attacker is able to run this code in the context of the remote service, which is LOCAL_SYSTEM. Depending on the nature of the injected code, the service may either terminate or continue to run. In the event that an attack causes service termination, the administrator of the remote machine will need to restart the service in order to regain the provided functionality. In the case of a witty worm attack, an infected system will send large amounts of UDP traffic, consisting of attack messages, to random destination IP addresses, which may overload local networks.
