Vulnerability Note VU#990451

Original Release Date: 2002-01-14 | Last Revised: 2002-01-14


AOL Instant Messenger (AIM) is an application that allows one peer to communicate with another. A vulnerability exists that can crash the client of a victim.


AIM allows users to send audio files to one another. By sending a corrupt WAV formatted file, an attacker can cause the victims client to crash.


By repeatedly sending this message with the file attached, a continued denial of service can be caused.


Upgrade your client. This has been fixed in version 4.8.2540 beta.

AIM permits the user to only accept messages from known/trusted peers. Enable this feature.
