Vulnerability Details

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the public_key_from_numbers (or EllipticCurvePublicNumbers.public_key()), EllipticCurvePublicNumbers.public_key(), load_der_public_key() and load_pem_public_key() functions do not verify that the point belongs to the expected prime-order subgroup of the curve. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification (ECDSA) and shared key negotiation (ECDH). When the victim computes the shared secret as S = [victim_private_key]P via ECDH, this leaks information about victim_private_key mod (small_subgroup_order). For curves with cofactor > 1, this reveals the least significant bits of the private key. When these weak public keys are used in ECDSA , it's easy to forge signatures on the small subgroup. Only SECT curves are impacted by this. This vulnerability is fixed in 46.0.5.

Vulnerability Details

Issue summary: Clients using RFC7250 Raw Public Keys (RPKs) to authenticate a
server may fail to notice that the server was not authenticated, because
handshakes don't abort as expected when the SSL_VERIFY_PEER verification mode
is set.
Impact summary: TLS and DTLS connections using raw public keys may be
vulnerable to man-in-middle attacks when server authentication failure is not
detected by clients.
RPKs are disabled by default in both TLS clients and TLS servers. The issue
only arises when TLS clients explicitly enable RPK use by the server, and the
server, likewise, enables sending of an RPK instead of an X.509 certificate
chain. The affected clients are those that then rely on the handshake to
fail when the server's RPK fails to match one of the expected public keys,
by setting the verification mode to SSL_VERIFY_PEER.
Clients that enable server-side raw public keys can still find out that raw
public key verification failed by calling SSL_get_verify_result(), and those
that do, and take appropriate action, are not affected. This issue was
introduced in the initial implementation of RPK support in OpenSSL 3.2.
The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
Mend Note: The description of this vulnerability differs from MITRE.

Vulnerability Details

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography would allow a peer named bar.example.com to validate against a wildcard leaf certificate for *.example.com, even if the leaf's parent certificate (or upwards) contained an excluded subtree constraint for bar.example.com. This issue has been patched in version 46.0.6.
