Description
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to improper resource management in session handling when processing connection attempts that do not send a LoginPacket. A remote attacker can create multiple unauthenticated sessions and keep them open to cause a denial of service.
Unauthenticated sessions are counted toward the max-players check until a 10-second login timeout is reached, which can cause legitimate players to be disconnected immediately when they attempt to join.
