The other functions affected by this are DH_check_ex() and EVP_PKEY_param_check().

An application calling any of those other functions may similarly be affected. The function DH_check() is itself called by a number of other OpenSSL functions. 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. 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. 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. The function DH_check() performs various checks on DH parameters.

Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service. 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. Issue summary: Checking excessively long DH keys or parameters may be very slow. This flaw allows an attacker to exhaust all available connections.

Due to their blocking nature, the Keylime registrar is subject to a remote denial of service against its SSL connections.
