CWE ID 1333


CVE-2023-3446 is a vulnerability that affects products such as OpenSSL, LGHY0F, S3oKWH, RjDw5I, QtrqC0, and ZEzzbP. The vulnerability arises from the use of excessively long Diffie-Hellman (DH) keys or parameters in applications that utilize the DH_check(), DH_check_ex(), or EVP_PKEY_param_check() functions. This can result in significant delays and potential denial of service (DoS) if untrusted keys or parameters are used. The risk score for this vulnerability is 31, indicating a medium level of danger. To mitigate the issue, organizations should ensure that they obtain keys and parameters from trusted sources and consider implementing restrictions on the size of modulus used.
