The fоllоwing cоde implements а UDP server thаt receives messаges from clients and creates a new thread to handle each received message. Assume all required header files are included. Find five distinct critical coding errors or design mistakes that may cause security problems, reliability problems, or incorrect behavior. The issues may involve memory safety, concurrency, networking semantics, resource management, or incorrect protocol behavior. For each issue, provide: The relevant line number(s). [1 pt]A one-sentence explanation of the problem and its possible impact. [1 pt]A one-sentence fix or mitigation.
