Fedora 38: python-cryptography 2023-749dd47c79
Summary
cryptography is a package designed to expose cryptographic primitives and
recipes to Python developers.
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.
