OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es):

  • openssl: Excessive time spent checking DH keys and parameters (CVE-2023-3446)

  • OpenSSL: Excessive time spent checking DH q parameter value (CVE-2023-3817)

  • openssl: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow (CVE-2023-5678)
