Issue summary: Checking excessively long DH keys or parameters may be very slow.  Impact summary: Applications that use the functions DH_check(), DH_check_ex() or EVP_PKEY_param_check() 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 this may lead to a Denial of Service.  The function DH_check() performs various checks on DH parameters. After fixing CVE-2023-3446 it was discovered that a large q parameter value can also trigger an overly long computation during some of these checks. A correct q value, if present, cannot be larger than the modulus p parameter, thus it is unnecessary to perform these checks if q is larger than p.  An application that calls DH_check() and supplies a key or parameters obtained from an untrusted source could be vulnerable to a Denial of Service attack.  The function DH_check() is itself called by a number of other OpenSSL functions. An application calling any of those other functions may similarly be affected. The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check().  Also vulnerable are the OpenSSL dhparam and pkeyparam command line applications when using the \"-check\" option.  The OpenSSL SSL/TLS implementation is not affected by this issue.  The OpenSSL 3.0 and 3.1 FIPS providers are not affected by this issue.\n\nFIRST-EPSS: 0.001640000\nNVD-IS: 1.4\nNVD-ES: 3.9", "creation_timestamp": "2023-12-02T02:24:58.000000Z"}, {"uuid": "aa73396c-d46b-4af2-b2db-12f124e117ba", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2023-3817", "type": "seen", "source": "https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0316/", "content": "", "creation_timestamp": "2026-03-19T00:00:00.000000Z"}, {"uuid": "f195fcf1-8ee4-4d63-9606-11ec352ffce9", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2023-38175", "type": "seen", "source": "https://t.me/arpsyndicate/848", "content": "#ExploitObserverAlert\n\nCVE-2023-38175\n\nDESCRIPTION: Exploit Observer has 1 entries related to CVE-2023-38175.

Issue summary: Generating excessively long X9.42 DH keys or checking excessively long X9.42 DH keys or parameters may be very slow.  Impact summary: Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays.

While DH_check() performs all the necessary checks (as of CVE-2023-3817), DH_check_pub_key() doesn't make any of these checks, and is therefore vulnerable for excessively large P and Q parameters.
