The vulnerabilities of the functions EllipticCurvePublicNumbers.public_key(), EllipticCurvePublicNumbers.public_key(), load_der_public_key(), and load_pem_public_key() in the Python-cryptography cryptographic library allow a perpetrator to gain access to confidential data.

The vulnerabilities of the functions EllipticCurvePublicNumbers.publickey, EllipticCurvePublicNumbers.publickey, loadderpublickey, and loadpempublickey in the Python-cryptography cryptographic library are related to insufficient validation of data authenticity. Exploiting these vulnerabilities...

Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in public key functions publickeyfromnumbers, EllipticCurvePublicNumbers.publickey, loadderpublickey, and loadpempublickey, which may reveal bits from a private key when provided with a...
