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.", "threat_severity": "Low"}
