Summary

CVE-2023-3446: Excessively long DH keys or parameters used in OpenSSL functions DH_check(), DH_check_ex(), and EVP_PKEY_param_check() can cause prolonged delays, potentially leading to a Denial of Service (DoS) attack. Affected applications may call these functions with untrusted key or parameter inputs, allowing an attacker to exploit this vulnerability. The SSL/TLS implementation in OpenSSL is not affected, but the dhparam and pkeyparam command line applications are vulnerable when using the '-check' option. The OpenSSL 3.0 and 3.1 FIPS providers are also not affected.
