Read Time:1 Minute, 5 Second

Robert Merget, Marcus Brinkmann, Nimrod Aviram, and Juraj Somorovsky
discovered that certain Diffie-Hellman ciphersuites in the TLS
specification and implemented by OpenSSL contained a flaw. A remote
attacker could possibly use this issue to eavesdrop on encrypted
communications. This was fixed in this update by removing the insecure
ciphersuites from OpenSSL. (CVE-2020-1968)

Paul Kehrer discovered that OpenSSL incorrectly handled certain input
lengths in EVP functions. A remote attacker could possibly use this issue
to cause OpenSSL to crash, resulting in a denial of service.
(CVE-2021-23840)

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)

Chancen and Daniel Fiala 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-2022-2068)

It was discovered that OpenSSL incorrectly handled excessively large
Diffie-Hellman parameters. An attacker could possibly use this issue
to cause a denial of service. (CVE-2023-3446)
