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 crehash script. A local attacker could possibly use this issue to execute arbitrary commands when crehash is run. (CVE-2022-1292)
Chancen and Daniel Fiala discovered that OpenSSL incorrectly handled the crehash script. A local attacker could possibly use this issue to execute arbitrary commands when crehash 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)
Bahaa Naamneh discovered that OpenSSL incorrectly handled certain malformed PKCS12 files. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2024-0727)
