The macros EVP_DigestSignUpdate() and + EVP_DigestVerifyUpdate() have been converted to functions. See the man + pages for further details. + [Matt Caswell] + + *) s390x assembly pack: add hardware-support for P-256, P-384, P-521, + X25519, X448, Ed25519 and Ed448. + [Patrick Steuer] + + *) Print all values for a PKCS#12 attribute with 'openssl pkcs12', not just + the first value. + [Jon Spillett] + + *) Deprecated the public definition of ERR_STATE as well as the function + ERR_get_state(). This is done in preparation of making ERR_STATE an + opaque type. + [Richard Levitte] + + *) Added ERR functionality to give callers access to the stored function + names that have replaced the older function code based functions. + + New functions are ERR_get_error_func(), ERR_peek_error_func(), + ERR_peek_last_error_func(), ERR_get_error_data(), ERR_peek_error_data(), + ERR_peek_last_error_data(), ERR_get_error_all(), ERR_peek_error_all() + and ERR_peek_last_error_all(). + + These functions have become deprecated: ERR_get_error_line_data(), + ERR_peek_error_line_data(), ERR_peek_last_error_line_data() and + ERR_func_error_string(). + [Richard Levitte] + + *) Extended testing to be verbose for failing tests only. The make variables + VERBOSE_FAILURE or VF can be used to enable this: + + $ make VF=1 test # Unix + $ mms /macro=(VF=1) test ! OpenVMS + $ nmake VF=1 test # Windows + + [Richard Levitte] + + *) For built-in EC curves, ensure an EC_GROUP built from the curve name is + used even when parsing explicit parameters, when loading a serialized key + or calling `EC_GROUP_new_from_ecpkparameters()`/ + `EC_GROUP_new_from_ecparameters()`. + This prevents bypass of security hardening and performance gains, + especially for curves with specialized EC_METHODs. + By default, if a key encoded with explicit parameters is loaded and later + serialized, the output is still encoded with explicit parameters, even if + internally a "named" EC_GROUP is used for computation. + [Nicola Tuveri] + + *) Compute ECC cofactors if not provided during EC_GROUP construction. Before + this change, EC_GROUP_set_generator would accept order and/or cofactor as + NULL. After this change, only the cofactor parameter can be NULL. It also + does some minimal sanity checks on the passed order. + (CVE-2019-1547) + [Billy Bob Brumley] + + *) Fixed a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey. + An attack is simple, if the first CMS_recipientInfo is valid but the + second CMS_recipientInfo is chosen ciphertext. If the second + recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct + encryption key will be replaced by garbage, and the message cannot be + decoded, but if the RSA decryption fails, the correct encryption key is + used and the recipient will not notice the attack. + As a work around for this potential attack the length of the decrypted + key must be equal to the cipher default key length, in case the + certifiate is not given and all recipientInfo are tried out. + The old behaviour can be re-enabled in the CMS code by setting the + CMS_DEBUG_DECRYPT flag. + [Bernd Edlinger] + + *) Early start up entropy quality from the DEVRANDOM seed source has been + improved for older Linux systems. The RAND subsystem will wait for + /dev/random to be producing output before seeding from /dev/urandom. + The seeded state is stored for future library initialisations using + a system global shared memory segment. The shared memory identifier + can be configured by defining OPENSSL_RAND_SEED_DEVRANDOM_SHM_ID to + the desired value. The default identifier is 114. + [Paul Dale] + + *) Revised BN_generate_prime_ex to not avoid factors 2..17863 in p-1 + when primes for RSA keys are computed. + Since we previously always generated primes == 2 (mod 3) for RSA keys, + the 2-prime and 3-prime RSA modules were easy to distinguish, since + N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting + 2-prime vs. 3-prime RSA keys was possible by computing N mod 3. + This avoids possible fingerprinting of newly generated RSA modules. + [Bernd Edlinger] + + *) Correct the extended master secret constant on EBCDIC systems. Without this + fix TLS connections between an EBCDIC system and a non-EBCDIC system that + negotiate EMS will fail. Unfortunately this also means that TLS connections + between EBCDIC systems with this fix, and EBCDIC systems without this + fix will fail if they negotiate EMS. + [Matt Caswell] + + *) Changed the library initialisation so that the config file is now loaded + by default. This was already the case for libssl. It now occurs for both + libcrypto and libssl. Use the OPENSSL_INIT_NO_LOAD_CONFIG option to + OPENSSL_init_crypto() to suppress automatic loading of a config file. + [Matt Caswell] + + *) Introduced new error raising macros, ERR_raise() and ERR_raise_data(), + where the former acts as a replacement for ERR_put_error(), and the + latter replaces the combination ERR_put_error()+ERR_add_error_data(). + ERR_raise_data() adds more flexibility by taking a format string and + an arbitrary number of arguments following it, to be processed with + BIO_snprintf(). + [Richard Levitte] + + *) Introduced a new function, OSSL_PROVIDER_available(), which can be used + to check if a named provider is loaded and available. When called, it + will also activate all fallback providers if such are still present. + [Richard Levitte] + + *) Enforce a minimum DH modulus size of 512 bits. + [Bernd Edlinger] + + *) Changed DH parameters to generate the order q subgroup instead of 2q. + Previously generated DH parameters are still accepted by DH_check + but DH_generate_key works around that by clearing bit 0 of the + private key for those. This avoids leaking bit 0 of the private key. + [Bernd Edlinger] + + *) Significantly reduce secure memory usage by the randomness pools. + [Paul Dale] *) {CRYPTO,OPENSSL}_mem_debug_{push,pop} are now no-ops and have been deprecated.
