Details

USN-5402-1 fixed several vulnerabilities in OpenSSL. This update provides
the corresponding update for Ubuntu 16.04 ESM.

Original advisory details:

Elison Niven discovered that OpenSSL incorrectly handled the c_rehash
script. A local attacker could possibly use this issue to execute arbitrary
commands when c_rehash is run. (CVE-2022-1292)

Aliaksei Levin discovered that OpenSSL incorrectly handled resources when
decoding certificates and keys. 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. (CVE-2022-1473)
