Details

It was discovered that the python-cryptography Cipher.update_into function
would incorrectly accept objects with immutable buffers. This would result
in corrupted output, contrary to expectations. This issue only affected
Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-23931)

It was dicovered that python-cryptography incorrectly handled loading
certain PKCS7 certificates. A remote attacker could possibly use this
issue to cause python-cryptography to crash, resulting in a denial of
service. This issue only affected Ubuntu 22.04 LTS, Ubuntu 23.04, and
Ubuntu 23.10. (CVE-2023-49083)
