CVE-2020-36242

The CVE refers to the Python cryptography package prior to 3.3.2. The issue arises from certain sequences of update() calls when symmetrically encrypting very large (multi-GB) payloads, which can trigger an integer overflow and buffer overflow, as demonstrated by the Fernet class. This affects cr...

Aff...

CVE-2026-26007

CVE-2026-26007 describes a vulnerability in the cryptography package where public_key_from_numbers, EllipticCurvePublicNumbers.public_key(), load_der_public_key(), and load_pem_public_key() do not validate that a key point belongs to the expected prime-order subgroup. This allows small-subgroup k...
