------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2023-672f668f51 2023-03-10 01:37:02.422983 ------------------------------------------------------------------------------- -
Name : python-cryptography Product : Fedora 36 Version : 36.0.0 Release : 4.fc36 URL : https://cryptography.io/en/latest/ Summary : PyCA's cryptography library Description : cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
------------------------------------------------------------------------------- - Update Information:
Security fix for CVE-2023-23931 cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In affected versions `Cipher.update_into` would accept Python objects which implement the buffer protocol, but provide only immutable buffers. This would allow immutable objects (such as `bytes`) to be mutated, thus violating fundamental rules of Python and resulting in corrupted output. This now correctly raises an exception. This issue has been present since `update_into` was originally introduced in cryptography 1.8. ------------------------------------------------------------------------------- - ChangeLog:
* Wed Feb 22 2023 Christian Heimes <cheimes@redhat.com> - 36.0.0-4 - Fix CVE-2023-23931: Don't allow update_into to mutate immutable objects, resolves rhbz#2171820 - Fix FTBFS due to failing test_load_invalid_ec_key_from_pem and test_decrypt_invalid_decrypt, resolves rhbz#2171661 ------------------------------------------------------------------------------- - References:
