Too easy to make server crash

[breakwa11]

just run:

import socket
ip = "127.0.0.1" # or "xxx.com"
port = 8388
try:
    addrs = socket.getaddrinfo(ip, port, 0, socket.SOCK_STREAM, socket.SOL_TCP)
    af, socktype, proto, canonname, sa = addrs[0]
    s = socket.socket(af, socket.SOCK_STREAM)
    s.connect(sa)
    s.send(b'a')
    s.recv(1024)
except:
    pass

What operating system?

[breakwa11]

Windows, bin from latest release

more issue here:
in function bool Encryptor::verifyHeaderAuth(const QByteArray &data, const int &headerLen) const
line 160: == data.mid(headerLen, Cipher::AUTH_LEN);
mid function may throw an exception

mid doesn't throw

I'll check the botan exception on Windows when I have spare time
