-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2023-749dd47c79 2023-03-11 03:04:11.186915 -------------------------------------------------------------------------------- Name : python-cryptography Product : Fedora 38 Version : 37.0.2 Release : 8.fc38 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@xxxxxxxxxx> - 37.0.2-8 - 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 * Fri Jan 20 2023 Fedora Release Engineering <releng@xxxxxxxxxxxxxxxxx> - 37.0.2-7 - Rebuilt for https://fedoraproject.org/wiki/Fedora_38_Mass_Rebuild * Fri Dec 9 2022 Christian Heimes <cheimes@xxxxxxxxxx> - 37.0.2-6 - Enable SHA1 signatures in test suite (ELN-only) -------------------------------------------------------------------------------- References: [ 1 ] Bug #2171817 - CVE-2023-23931 python-cryptography: memory corruption via immutable objects https://bugzilla.redhat.com/show_bug.cgi?id=2171817 -------------------------------------------------------------------------------- This update can be installed with the "dnf" update program.
