MOOS core-moos through 10.4.0 contains a denial of service vulnerability in MOOSCommServer::ListenLoop() where the accept thread performs a blocking receive without timeout during the wire-protocol handshake. An attacker can open a TCP connection to the MOOSDB port and send no data, causing the accept thread to block indefinitely while holding the socket-list lock, preventing all subsequent client connections.
