1. Side-aware ML-KEM in TLS (tls.c, tls13.c, ssl.c, internal.h):
TLSX_IsGroupSupported/TLSX_UseSupportedCurve take a `side` arg; new
TLSX_IsMlKemGroupSupported + client/server support macros. A build only
capable of one ML-KEM op no longer advertises groups it can't use for
its role.
2. NO_ASN_TIME support (ssl_asn1.c, ssl.h, settings.h): data-only
ASN1_TIME APIs now compile without system time; OCSP responder
auto-disabled under NO_ASN_TIME.
3. SP ECC (sp_*.c, sp_x86_64_asm.asm): curve `b` constants and
sp_ecc_is_point_* always compiled (point-check available in more
configs); asm movsxd -> movsx.
4. configure.ac: BUILD_MEMUSE fixed to trigger on != "xno".
5. Test fixes: HRR-aware TLS 1.3 memio tests (new
test_memio_msg_is_hello_retry_request); tightened build guards
(Ed25519/Ed448 key-import, AES decrypt, XMSS heights, SP sizes,
static-PSK).
* don't disable URI validation when defined(WOLFSSL_FPKI).
* return immediately with ASN_ALT_NAME_E when URI contains an unexpected '/', as in asn_orig.c DecodeAltNames(), fixing OOB read defect.
wolfcrypt/src/asn_orig.c: fix URI validation gating (ignore WOLFSSL_FPKI) in DecodeAltNames().
tests/api/test_certman.c: fix uriSan in test_wolfSSL_X509_check_host_URI_SAN_not_DNS_match() (make it a URI).
tests/api.c: align gating in test_wolfSSL_URI() with new dynamics (URIs validated regardless of defined(WOLFSSL_FPKI)).
- pkcs7.c: wrap the AuthEnvelopedData encryptedContentSz bounds check
entirely in #ifdef NO_PKCS7_STREAM so the default streaming build
carries no empty/no-op branch (behavior unchanged).
- test_pkcs7.c: assert the encoded size is >32 so the encSz-32 and
encSz-1 truncations can't underflow.
authorized any responder issued by an ancestor of the target's issuer;
RFC 6960 4.2.2.2 requires direct issuance by the CA identified in the
request.
- Remove CheckOcspResponderChain() and WOLFSSL_NO_OCSP_ISSUER_CHAIN_CHECK.
- Drop now-unused vp parameter from CheckOcspResponder() and the
OcspRespCheck() helper; cascade through template and non-template
paths.
OCSP test blobs:
- Re-sign resp_server1_cert with intermediate1-ca (CA-direct path).
- Add resp_server1_cert_ancestor_responder for the negative test.
- Embed server1_cert_pem[] in test_ocsp_test_blobs.h so the new test
runs under NO_FILESYSTEM; matching entry added to
create_ocsp_test_blobs.py.
- Regenerate response[] in test_certman.c with intermediate1-ca as
signer; recipe switched from Wireshark export to openssl -respout
+ xxd -i for reproducibility.
- Fix self-XOR in test_wolfSSL_CertManagerCheckOCSPResponse so the
serial byte actually flips (^= 0xFF).
Live OCSP coverage:
- Add ocsp-responder-int1 (delegated responder issued directly by
intermediate1-ca, with id-kp-OCSPSigning EKU) for the
responder->intermediate->root chain.
- scripts/ocsp-stapling.test: intermediate1 responder switched to
ocsp-responder-int1 (delegated path).
- scripts/ocsp-stapling2.test, scripts/ocsp-stapling_tls13multi.test:
intermediate2 and intermediate3 sign their OCSP responses with
their own CA keys (CA-direct path); root block unchanged
(ocsp-responder-cert is still RFC-compliant for root-issued certs).
- .github/workflows/ocsp.yml: server1 OCSP responder switched to
ocsp-responder-int1 to match the cert chain.
- New test_ocsp_ancestor_responder_rejected confirms the
ancestor-issued response is rejected with OCSP_LOOKUP_FAIL.
1. BasicConstraints pathLenConstraint absent vs. 0 —
get_ext_d2i/set_ext/V3_EXT_d2i now distinguish "no constraint" from 0
per RFC 5280 §4.2.1.9, using the existing basicConstPlSet flag.
2. GENERAL_NAME_print GEN_DIRNAME — added missing return-value
normalization so the directory name is actually printed (was emitting
only DirName:).
3. GENERAL_NAME_print GEN_DNS — use ASN1_STRING_print like the EMAIL/URI
cases, avoiding NULL-strData deref and NUL-truncation.
4. X509_print BasicConstraints — print , pathlen:N to match OpenSSL.
5. X509_print Extended Key Usage — print Any Extended Key Usage (was
omitted).
6. get_ext_d2i CRL_DIST_OID double-free — null gn immediately after
ownership transfers to dp, so an error from the next push doesn't free
it twice.
7. X509V3_EXT_print SAN truncation/failure — match XSNPRINTF size cap to
the allocation; was truncating at indent==1 and failing at indent>=2.
8. X509V3_EXT_print AUTH_KEY/SUBJ_KEY NULL deref — NULL-check
i2s_ASN1_STRING return before passing to %s.
9. X509_add_ext SAN type confusion — reject DIRNAME/RID/X400/EDIPARTY;
only the ASN1_STRING*-backed types are read via gn->d.ia5. Was
performing a wild-pointer XMEMCPY in add_altname_ex.
Also: extracted the SAN and WOLFSSL_CUSTOM_OID arms of X509_add_ext into
static helpers (behavior-preserving).
Regression tests added for #1–5 and #9; existing GENERAL_NAME_print test
hardened (gives GEN_DIRNAME a real directoryName, eliminating an OOB
read that the print fix would otherwise expose).
Add defense-in-depth checks to wc_ed{25519,448}_check_key() and
ed{25519,448}_verify_msg_final_with_sha() that reject the identity
point and other small-order public keys. Honest EdDSA key generation
never produces such keys, but wolfSSL previously accepted them on
import and verification. The guard runs at both entry points so it
holds even when a key is imported with trusted=1. New tests are gated
on !HAVE_FIPS || FIPS_VERSION3_GE(7,0,0).
TLS_EMPTY_RENEGOTIATION_INFO_SCSV appears in GetCipherNames() when
HAVE_RENEGOTIATION_INDICATION is set. It is a signaling value, not a
real suite; set_cipher_list accepts it but the handshake rejects it
with UNSUPPORTED_SUITE. Add it to record_size_skip_cipher's deny list.
wolfssl_local_GetRecordSize() runs BuildMessage(sizeOnly=1) on every
wolfSSL_write hot path. For AEAD ciphers the overhead is constant per
connection framing state, so cache (recordSz - payloadSz) on WOLFSSL
and invalidate in SetKeysSide(), at cidInfo->tx assignment, and in
wolfSSL_clear(). BuildMessage stays the single source of truth.
Add test_record_size_matches_build_message (cross-checks every built
cipher over TLS/DTLS +/- CID against BuildMessage) and
test_record_size_cache_invalidated_on_renegotiation.
Move out DTLS 1.3 specific tests into test_dtls13.c. (Also move out from
test_dtls.c)
Move out DTLS tests into test_dtls.c.
Move out LMS and XMSS tests into test_lms_xmss.c.
Move out SSL session tests into test_session.c.
Move out remaining ML-DSA/Dilithium tests in api.c into test_mldsa.c.
test_dtls13_oversized_cert_chain (added upstream in 1653ecd07) loaded a >9-cert chain to exercise SendTls13Certificate's word16 overflow guard. This PR now rejects over-MAX_CHAIN_DEPTH chains at load in ProcessUserChain, so the chain never reaches the send path; the load-time rejection is covered by test_wolfSSL_CTX_use_certificate_chain_buffer_max_depth. The word16 send guard remains as defense-in-depth (now only reachable via large PQC chains).
Enable all-zero shared secret check for Curve448/25519 by default. Ensure post_handshake_auth extension was sent before accepting post-handshake CertificateRequest message.
Add `*pp == NULL` checks to three d2i wrappers to prevent NULL deref
on public OpenSSL-compat APIs:
- d2i_evp_pkey (reachable via wolfSSL_d2i_PublicKey/PrivateKey)
- wolfSSL_d2i_OCSP_RESPONSE
- wolfSSL_d2i_ECDSA_SIG (template-ASN crash)
Also add regression tests for the existing PR fixes: ProcessBuffer
negative-size, PemToDer family negative-pemSz, GetCRLInfo negative-sz,
wc_Set*Buffer derSz<0, and d2i_ECDSA_SIG negative-length / *pp==NULL.
wolfssl/wolfcrypt/wc_mldsa.h: move WOLFSSL_MLDSA_NO_CTX setup to precede legacy dilithium.h header, so that the _NO_CTX remap macros are properly gated in.
