Summary: python-pycryptodome security update

Details: PyCryptodome is a self-contained Python package of low-level cryptographic primitives. It supports Python 2.6 and 2.7, Python 3.4 and newer, and PyPy. You can install it with:: pip install pycryptodome All modules are installed under the ``Crypto`` package. Check the pycryptodomex_ project for the equivalent library that works under the ``Cryptodome`` package. PyCryptodome is a fork of PyCrypto. It brings several enhancements with respect to the last official version of PyCrypto (2.6.1), for instance: * Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB) * Accelerated AES on Intel platforms via AES-NI * First class support for PyPy * Elliptic curves cryptography (NIST P-256, P-384 and P-521 curves only) * Better and more compact API (`nonce` and `iv` attributes for ciphers, automatic generation of random nonces and IVs, simplified CTR cipher mode, and more) * SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms * Salsa20 and ChaCha20 stream ciphers * scrypt and HKDF * Deterministic (EC)DSA * Password-protected PKCS#8 key containers * Shamir's Secret Sharing scheme * Random numbers get sourced directly from the OS (and not from a CSPRNG in userspace) * Simplified install process, including better support for Windows * Cleaner RSA and DSA key generation (largely based on FIPS 186-4) * Major clean ups and simplification of the code base PyCryptodome is not a wrapper to a separate C library like *OpenSSL*. To the largest possible extent, algorithms are implemented in pure Python. Only the pieces that are extremely critical to performance (e.g. block ciphers) are implemented as C extensions. For more information, see the `homepage`_. All the code can be downloaded from `GitHub`_. Security Fix(es): PyCryptodome and pycryptodomex before 3.19.1 allow side-channel leakage for OAEP decryption, exploitable for a Manger attack.(CVE-2023-52323)
