DoClientTicketCheck's ticket-age bounds (-1000 ms low bound and
MAX_TICKET_AGE_DIFF*1000+1000 ms high bound) were never exercised by
any integration test, so mutations of the constants went undetected.
Establish a TLS 1.3 session, read the NewSessionTicket, then shift the
client's cached ageAdd by well over 1 second so the server's
unobfuscated diff falls outside the valid window on resumption. The
server must reject the PSK — session_reused stays 0.
DoTls13ClientHello enforces RFC 8446 Section 4.1.4 by comparing the
cipher suite in the second ClientHello to the hrrCipherSuite cached on
the server from the HelloRetryRequest. No existing test covers the
mismatch branch, so a deletion of the check would silently allow a
client to switch cipher suite between CH1 and CH2. Drive a partial
handshake until the server has emitted the HRR, then flip the cached
hrrCipherSuite on the server; processing CH2 must surface
INVALID_PARAMETER.
wolfSSL_TicketKeyCb is the built-in ticket callback registered by the
OpenSSL-compat wolfSSL_CTX_set_tlsext_ticket_key_cb API. Its
ConstantCompare of the ticket HMAC was never reached in any test, so a
deletion of the check would silently accept forged tickets. New test
sets up the compat callback, establishes a TLS 1.2 session, saves it,
flips a byte of the encrypted ticket, and asserts the resumption
attempt does not complete.
Cover both branches of TLSX_SecureRenegotiation_Parse's ConstantCompare
against the cached Finished verify_data: a single memio test loops
over client-side and server-side corruption, renegotiates, and
asserts the offending peer surfaces SECURE_RENEGOTIATION_E.
Tls13IntegrityOnly_Decrypt was completely untouched by existing tests,
so any mutation of its ConstantCompare would pass CI. Add a memio
TLS 1.3 handshake over TLS13-SHA256-SHA256 (integrity-only NULL cipher),
then corrupt the final byte of the next record body via an IORecv
wrapper and assert the server surfaces DECRYPT_ERROR.
Cover the Poly1305 ConstantCompare tag check in ChachaAEADDecrypt that
no existing test was hitting (VERIFY_MAC_ERROR never expected in the
suite). A memio-based TLS 1.2 handshake over
ECDHE-RSA-CHACHA20-POLY1305 completes, the server's IORecv is then
replaced with a wrapper that flips the final byte of the next record
body so the forged Poly1305 tag no longer matches. The server's
wolfSSL_read must surface VERIFY_MAC_ERROR.
Covers the HandleResumeHistory check that RFC 7627 Section 5.3 requires:
if the original session used Extended Master Secret, the server MUST
abort when a resumption ClientHello is received without EMS. The new
memio test performs a TLS 1.2 handshake with EMS, saves the session,
disables EMS on a fresh client, resumes with the saved session, and
asserts the server returns EXT_MASTER_SECRET_NEEDED_E.
* Fix OOB heap reads via TLSX_ExtractEch() by preemptively rejecting oversized
SNI names in TLSX_UseSNI().
* In TLSX_EchChangeSNI(), don't attempt to truncate if an oversized name is
seen, just return error.
* Move definition of WOLFSSL_HOST_NAME_MAX to an ungated context in ssl.h, and
use it consistently in tls.c, eliminating the duplicative
WOLFSSL_HOST_NAME_MAX.
utilities for generic SetKey and ExportKey operations on HMAC, RSA, ECC,
and AES. Add wc_ecc_size/wc_ecc_sig_size callback hooks for hardware-only
keys. Integrate into configure.ac as --enable-cryptocbutils=setkey,export
options with CI test configurations in os-check.yml.
Add test handlers in test.c and api.c with export/import delegation
pattern, small-stack-safe allocations, custom curve support, and
DEBUG_CRYPTOCB helpers.
ssl->secure_renegotiation caches a pointer into extension data owned by
the ssl->extensions list. Three call sites free that list via TLSX_FreeAll
without NULLing the cached pointer, leaving it dangling:
- wolfSSL_clear()
- FreeHandshakeResources() (TLSX_FreeAll branch)
- wolfSSL_ResourceFree()
After wolfSSL_clear(), calling wolfSSL_SSL_get_secure_renegotiation_support()
reads the freed SecureRenegotiation struct. Confirmed heap-use-after-free
under ASan with nginx, haproxy, and openssl-compat build profiles.
NULL the pointer at all three sites. Add regression test covering the
wolfSSL_clear path.
