"details": "It was discovered that the python-cryptography Cipher.update_into function\nwould incorrectly accept objects with immutable buffers. This would result\nin corrupted output, contrary to expectations. This issue only affected\nUbuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 23.04. (CVE-2023-23931)\n\nIt was dicovered that python-cryptography incorrectly handled loading\ncertain PKCS7 certificates. A remote attacker could possibly use this\nissue to cause python-cryptography to crash, resulting in a denial of\nservice. This issue only affected Ubuntu 22.04 LTS, Ubuntu 23.04, and\nUbuntu 23.10.
