The ICQ ActiveList Server allows remote attackers to cause a denial of service (crash) by sending malformed packets to the server's UDP port.

Attackers can exploit this vulnerability to disrupt the server's operation, potentially leading to communication downtime.

It is recommended to monitor traffic to the server's UDP port and implement packet filtering to block malicious data.
