Who is Vulnerable?
Vulnerability Description The AOL ICQ product is a messaging application widely used by home users and in small to medium size companies. The messenger application ships with various extra features in addition to its regular function of text message exchanges. One such feature introduced in the ICQ clients is the ability to make phone calls through the Internet. There exists a vulnerability in an ActiveX control embedded in the AOL ICQ product. The flaw is due to an improper handling of the parameters passed to a certain function of the affected ActiveX control. By sending a crafted message, a remote attacker may execute arbitrary code with the privileges of the currently logged on user. In case of a successful attack, the behavior of the target host is entirely dependent on the intended function of the supplied executable file. The file in such a case would execute within the security context of the currently logged-in user.
