Updated python-cryptography packages fix security vulnerability

Publication date: 27 Feb 2023
Modification date: 27 Feb 2023
Type: security
Affected Mageia releases : 8
CVE: CVE-2023-23931

Description

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. (CVE-2023-23931)
