Description

Updated python-cryptography packages fix security vulnerability 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)

Affected Systems

  • mageia•python-cryptography

    < 3.3.1-1.2.mga8
