CVE-2026-27459
pyOpenSSL: DTLS cookie callback buffer overflow
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD, Photon OS. Niedriger laut GHSA (hoch), Red Hat (hoch), Azure Linux (hoch), Ubuntu (mittel).
Beschreibung
pyOpenSSL is a Python wrapper around the OpenSSL library. Starting in version 22.0.0 and prior to version 26.0.0, if a user provided callback to `set_cookie_generate_callback` returned a cookie value greater than 256 bytes, pyOpenSSL would overflow an OpenSSL provided buffer. Starting in version 26.0.0, cookie values that are too long are now rejected.
