Tony Battersby discovered that OpenSSL incorrectly handled key and
initialization vector (IV) lengths. This could lead to truncation issues
and result in loss of confidentiality for some symmetric cipher modes.
(CVE-2023-5363)

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)
