A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.
Отчет
This vulnerability exists due to an incomplete fix for CVE-2020-25659. The CVE-2020-25659 vulnerability presents a moderate severity concern due to its specific impact on applications utilizing RSA decryption with PKCS#1 v1.5 padding. While the vulnerability could potentially lead to leakage in RSA decryption operations, its severity is downgraded to moderate by several factors. Firstly, the exploitability of the vulnerability is limited to scenarios where RSA decryption with PKCS#1 v1.5 padding is employed, narrowing the scope of affected systems. Additionally, the implementation of implicit rejection, such as the Marvin workaround, provides a viable mitigation strategy. https://people.redhat.com/~hkario/marvin/
