Description

Overview

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.

Description

AIM permits users to send files from one peer to another. By sending a file with a long name, it is possible to crash the client of the recipient.


Impact

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


Solution

This has been resolved in AIM for Windows beta version 4.8.2540.


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