Details

USN-5845-1 fixed several vulnerabilities in OpenSSL. This update provides
the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

Original advisory details:

David Benjamin discovered that OpenSSL incorrectly handled X.400 address
processing. A remote attacker could possibly use this issue to read
arbitrary memory contents or cause OpenSSL to crash, resulting in a denial
of service. (CVE-2023-0286)

Octavio Galland and Marcel Böhme discovered that OpenSSL incorrectly
handled streaming ASN.1 data. A remote attacker could use this issue to
cause OpenSSL to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2023-0215)
