CVE-2025-13836 Excessive read buffering DoS in http.client

When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This allows a malicious server to cause the client to read large amounts of data into memory, potentially causing OOM or other DoS...

CVE-2025-13836

CVE-2025-13836 affects Python CPython: when reading an HTTP response with no explicit read amount, the client may default to Content-Length, enabling a malicious server to cause excessive data buffering and potential OOM/DoS. Public advisories confirm fixes in multiple distributions and versions ...

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...
