Problem
In TCP, to improve the safety of the protocol, a node usually needs to select the port number and the start of the sequence number randomly. Now we assume that a popular operating system with the name of "Doors 2022" uses a random number generator that is flawed. If two random numbers are generated very close in time. the difference between them has 30% probability to be multiple of 265729 (which is a prime number). Explain how this flaw will impact the safety of TCP.
