CVE-2025-59089 Python-kdcproxy: remote dos via unbounded tcp upstream buffering

If an attacker causes kdcproxy to connect to an attacker-controlled KDC server e.g. through server-side request forgery, they can exploit the fact that kdcproxy does not enforce bounds on TCP response length to conduct a denial-of-service attack. While receiving the KDC's response, kdcproxy copie...
