SCA: security update for cryptography (GHSA-g6cj-pr64-35w5)

high Tenable Self-Hosted Container Security Plugin ID 445592

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
 From 44.0.0 until 50.0.0, pkcs7_decrypt_der, pkcs7_decrypt_pem, and pkcs7_decrypt_smime reported the
 outcome of decrypting a RecipientInfo's encryptedKey in several distinguishable ways, one of which
 disclosed the exact length recovered from the RSA operation. The same distinction was also observable by
 timing. An application that decrypts attacker-supplied EnvelopedData and reflects the outcome gives the
 attacker a Bleichenbacher oracle against the content-encryption key. Decryption ran as RSA PKCS#1 v1.5
 decrypt of encryptedKey, build an AES cipher from the result, then AES-CBC decrypt and PKCS#7 unpad.
 Invalid RSA padding, a valid padding with a bad key length, a correct length with a wrong key, and the
 real key each failed or succeeded differently. Case 1 is reachable only where the linked library lacks
 implicit rejection: OpenSSL 3.0 and 3.1, LibreSSL, and BoringSSL. Exploitation requires a service that
 auto-decrypts untrusted EnvelopedData matching the victim certificate and answers adaptively at high
 volume, such as an S/MIME gateway or mail filter. This issue is fixed in 50.0.0. (CVE-2026-69247)

Solution

Update the cryptography library and its related packages to version 50.0.0 or later.
