 It was discovered that python-cryptography incorrectly handled memory
 operations when processing mismatched PKCS#12 keys. A remote attacker could
 possibly use this issue to cause python-cryptography to crash, leading to a
 denial of service. This issue only affected Ubuntu 23.10. (CVE-2024-26130)");
