Juerg Wullschleger discovered that OpenSSL incorrectly handled the AES-SIV
cipher. This could lead to empty data entries being ignored, resulting in
certain applications being misled. This issue only affected Ubuntu 22.04
LTS and Ubuntu 23.04. (CVE-2023-2975)

It was discovered that OpenSSL incorrectly handled checking excessively
long DH keys or parameters. A remote attacker could possibly use this issue
to cause OpenSSL to consume resources, leading to a denial of service. This
issue only affected Ubuntu 22.04 LTS and Ubuntu 23.04. (CVE-2023-3446,
CVE-2023-3817)");
