This security flaw occurs because the applications that use the DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source may lead to a denial of service.",

"text": "The CVE-2023-3446 vulnerability in OpenSSL has been classified as having a low impact due to several factors. Firstly, while the potential for a Denial of Service (DoS) attack exists, it requires specific conditions to be met, notably the use of DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions with DH keys or parameters obtained from untrusted sources. Secondly, the issue primarily affects the efficiency of key and parameter checks, rather than directly compromising the security or integrity of cryptographic operations. Given these considerations and the absence of widespread exploitation or significant consequences beyond performance degradation, the overall impact of this vulnerability is deemed low rather than moderate.",
