aMSN (Alvaro's Messenger) is vulnerable to a denial of service condition when a remote attacker repeatedly sends crafted data to the default file-transfer port (TCP 6891). This causes the client to hang and terminates the user's instant-messaging session. The vulnerability is due to improper handling of unexpected or malformed data on the file-transfer port, leading to resource exhaustion or unhandled exceptions.
