**Name of the Vulnerable Software and Affected Versions** Cerulean Studios Trillian version 3.0 **Description** The issue allows remote attackers to cause a denial of service, resulting in the application crashing. This is triggered when a reverse direct connection is made using the ICQ protocol with a different ICQ client. **Recommendations** For version 3.0, consider disabling the ICQ protocol or restricting reverse direct connections to prevent the denial of service. As a temporary workaround, avoid using the ICQ protocol with different ICQ clients until a fix is available. At the moment, there is no information about a newer version that contains a fix for this issue.
