    The updated package fixes a security vulnerability:
    
    In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN
    response buffer is not initialized properly. There is a leak of
    information between different client connections. One client (an attacker)
    could use their connection to intelligently query coturn to get interesting
    bytes in the padding bytes from the connection of another client.
