- Fixed numerous minor grammar, spelling, wording, and punctuation
issues.
3.5.1 - Security release
* A malicious certificate can cause an infinite loop.
Reported by and fix from Tavis Ormandy and David Benjamin, Google.
3.5.0 - Development release
* New Features
- The RFC 3779 API was ported from OpenSSL. Many bugs were fixed,
regression tests were added and the code was cleaned up.
- Certificate Transparency was ported from OpenSSL. Many internal
improvements were made, resulting in cleaner and safer code.
Regress coverage was added. libssl does not yet make use of it.
* Portable Improvements
- Fixed various POSIX compliance and other portability issues
found by the port to the Sortix operating system.
- Add libmd as platform specific libraries for Solaris.
Issue reported from (ihsan <at> opencsw org) on libressl ML.
- Set IA-64 compiler flag only if it is HP-UX with IA-64.
Suggested from Larkin Nickle (me <at> larbob org) by libressl ML.
- Enabled and scheduled Coverity scan.
Contributed by Ilya Shipitsin (chipitsine <at> gmail com> on github.
* Compatibility Changes
- Most structs that were previously defined in the following headers
are now opaque as they are in OpenSSL 1.1:
bio.h, bn.h, comp.h, dh.h, dsa.h, evp.h, hmac.h, ocsp.h, rsa.h,
x509.h, x509v3.h, x509_vfy.h
- Switch TLSv1.3 cipher names from AEAD- to OpenSSL's TLS_
OpenSSL added the TLSv1.3 ciphersuites with "RFC names" instead
of using something consistent with the previous naming. Various
test suites expect these names (instead of checking for the much
more sensible cipher numbers). The old names are still accepted
as aliases.
- Subject alternative names and name constraints are now validated
when they are added to certificates. Various interoperability
problems with stacks that validate certificates more strictly
than OpenSSL can be avoided this way.
- Attempt to opportunistically use the host name for SNI in s_client
* Bug fixes
- In some situations, the verifier would discard the error on an
unvalidated certificate chain. This would happen when the
verification callback was in use, instructing the verifier to
continue unconditionally. This could lead to incorrect decisions
being made in software.
- Avoid an infinite loop in SSL_shutdown()
- Fix another return 0 bug in SSL_shutdown()
- Handle zero byte reads/writes that trigger handshakes in the
TLSv1.3 stack
- A long standing memleak in libtls CRL handling was fixed
* Internal Improvements
- Cache the SHA-512 hash instead of the SHA-1 hash and cache
notBefore and notAfter times when X.509 certificates are parsed.
- The X.509 lookup code has been simplified and cleaned up.
- Fixed numerous issues flagged by coverity and the cryptofuzz
project
- Increased the number of Miller-Rabin checks in DH and DSA
key/parameter generation
- Started using the bytestring API in libcrypto for cleaner and
safer code

SSL_set_ciphersuites SSL_set_max_early_data
SSL_set_post_handshake_auth
SSL_set_psk_use_session_callback
SSL_verify_client_post_handshake SSL_write_early_data
- Added AES-GCM constants from RFC 7714 for SRTP.
* Compatibility Changes
- Implement flushing for TLSv1.3 handshakes behavior, needed for Apache.
- Call the info callback on connect/accept exit in TLSv1.3,
needed for p5-Net-SSLeay.
- Default to using named curve parameter encoding from
pre-OpenSSL 1.1.0, adding OPENSSL_EC_EXPLICIT_CURVE.
- Do not ignore SSL_TLSEXT_ERR_FATAL from the ALPN callback.
* Testing and Proactive Security
- Added additional state machine test coverage.
- Improved integration test support with ruby/openssl tests.
- Error codes and callback support in new X.509 validator made
compatible with p5-Net_SSLeay tests.
* Internal Improvements
- Numerous fixes and improvements to the new X.509 validator to
ensure compatible error codes and callback support compatible
with the legacy OpenSSL validator.
3.4.0 - Development release
* Add support for OpenSSL 1.1.1 TLSv1.3 APIs.
* Enable new x509 validator.
* More details to come, testing is appreciated.
3.3.5 - Security fix
* A stack overread could occur when checking X.509 name constraints.
From GoldBinocle on GitHub.
* Enable X509_V_FLAG_TRUSTED_FIRST by default in the legacy verifier.
This compensates for the expiry of the DST Root X3 certificate.
3.3.4 - Security fix
* In LibreSSL, printing a certificate can result in a crash in
X509_CERT_AUX_print().
From Ingo Schwarze
* Ensure GNU-stack is set on ELF platforms when building with CMake to
enable non-executable stack annotations for the GNU toolchain.
From Tobias Heider
3.3.3 - Stable release
* This is the first stable release from the 3.3.x series.
There are no changes from 3.3.2.
3.3.2 - Development release
* This release adds support for DTLSv1.2 and continues the rewrite
of the record layer for the legacy stack. Numerous bugs and
interoperability issues were fixed in the new verifier. A few bugs
and incompatibilities remain, so this release uses the old verifier
by default. The OpenSSL 1.1 TLSv1.3 API is not yet available.
* Switch finish{,_peer}_md_len from an int to a size_t.
* Make SSL_get{,_peer}_finished() work when used with TLSv1.3.
* Use EVP_MD_MAX_MD_SIZE instead of 2 * EVP_MD_MAX_MD_SIZE as size
for cert_verify_md[], finish_md[] and peer_finish_md[]. The factor 2
was a historical artefact.
* Correct the return value type from ERR_peek_error() to a long.
* Avoid use of uninitialized in ASN1_time_parse() which could happen
on parsing UTCTime if the caller did not initialise the passed
struct tm.
* Destroy the mutex in a tls_config object on tls_config_free().
* Free alert_data and phh_data in tls13_record_layer_free()
these could leak if SSL_shutdown() or tls_close() were called
after closing the underlying socket().
* Free struct members in tls13_record_layer_free() in their natural
order for reviewability.
* Gracefully handle root certificates being both trusted and
untrusted.
* Handle X509_V_ERR_UNABLE_TO_VERIFY_LEAF_SIGNATURE in the new
verifier.
* Use the legacy verifier when building auto chains for TLS.
* Use consistent names in tls13_{client,server}_finished_{recv,send}().
* Add tls13_secret_{init,cleanup}() and use them throughout the
TLSv1.3 code base.
* Move the read MAC key into the TLSv1.2 record layer.
* Make tls12_record_layer_free() NULL safe.
* Search the intermediates only after searching the root certs in the
new verifier to avoid problems with the legacy callback.
* Bail out early after finding a single chain in the new verifier, if
we have been called via the legacy verifier API.
* Set (invalid and likely incomplete) chain on the xsc on chain build
failure prior to calling the callback. This is required by various
callers, including auto chain.
* Align SSL_get_shared_ciphers() with OpenSSL. This takes into account
that it never returned server ciphers, so now it will fail when
called from the client side.
* Add support for SSL_get_shared_ciphers() with TLSv1.3.
* Split the record protection from the TLSv1.2 record layer.
* Clean up sequence number handling in the new TLSv1.2 record layer.
* Clean up sequence number handling in DTLS.
* Clean up dtls1_reset_seq_numbers().
* Factor out code for explicit IV length, block size and MAC length
from tls12_record_layer_open_record_protected_cipher().
* Provide record layer overhead for DTLS.
* Provide functions to determine if TLSv1.2 record protection is
engaged.
* Add code to handle change of cipher state in the new TLSv1.2 record
layer.
* Mop up now unused dtls1_build_sequence_numbers() function.
* Allow setting a keypair on a tls context without specifying the
private key, and fake it internally in libtls. This removes the
need for privsep engines like relayd to use bogus keys.
* Skip the private key check for fake private keys.
* Move the private key setup from tls_configure_ssl_keypair() to a
helper function with proper error checking.
* Change the internal tls_configure_ssl_keypair() function to
return -1 instead of 1 on failure.
* Move sequence numbers into the new TLSv1.2 record layer.
* Move AEAD handling into the new TLSv1.2 record layer.
* Remove direct assignment of aead_ctx to avoid a leak.
* Add a number of RPKI OIDs from RFC 6482, 6484, 6493, 8182, 8360,
draft-ietf-sidrops-rpki-rta, and draft-ietf-opsawg-finding-geofeeds.
* Fail early in legacy exporter if the master secret is not available
to avoid a segfault if it is called when the handshake is not
completed.
* Factor out legacy stack version checks.
* Correct handshake MAC/PRF for various TLSv1.2 cipher suites which
were originally added with the default handshake MAC and PRF rather
than the SHA256 handshake MAC and PRF.
* Absorb ssl3_get_algorithm2() into ssl_get_handshake_evp_md().
* Use dtls1_record_retrieve_buffered_record() to load buffered
application data.
* Enforce read ahead with DTLS.
* Remove bogus DTLS checks that disabled ECC and OCSP.
* Sync cert.pem with Mozilla NSS root CAs except "GeoTrust Global CA".
* Only print the certificate file once on verification failure.
* Pull in fix for EVP_CipherUpdate() overflow from OpenSSL.
* Clean up and simplify dtls1_get_cipher().
* Group HelloVerifyRequest decoding and add missing check for trailing
data.
* Revise HelloVerifyRequest handling for DTLSv1.2.
* Handle DTLS1_2_VERSION in various places.
* Add DTLSv1.2 methods.
* Make SSL{_CTX,}_get_{min,max}_proto_version() return a version of
zero if the minimum or maximum has been set to zero to match
OpenSSL's behavior.
* Rename the "truncated" label into "decode_err" and the "f_err"
label into "fatal_err".
* Factor out and change some of the legacy client version code.
* Simplify version checks in the TLSv1.3 client. Ensure that the
server announced TLSv1.3 and nothing higher and check that the
legacy_version is set to TLSv1.2 as required by RFC 8446.
* Fix an off-by-one in x509_verify_set_xsc_chain() to make sure that
the new validator checks for EXFLAG_CRITICAL in
x509_vfy_check_chain_extension() for all untrusted certs in the
chain. Take into account that the root is not necessarily trusted.
* Avoid passing last and depth to x509_verify_cert_error() on ENOMEM.
* Rename depth to num_untrusted.
* Only use TLS versions internally rather than both TLS and DTLS
versions since the latter are the one's complement of the human
readable version numbers, which means that newer versions decrease
in value.
* Fix two bugs in the legacy verifier that resulted from refactoring
of X509_verify_cert() for the new verifier: a return value was
incorrectly treated as boolean, making it insufficient to decide
whether validation should carry on or not.
* Identify DTLS based on the version major value.
* Move handling of cipher/hash based cipher suites into the new record
layer.
* Add tls12_record_protection_unused() and call it from CCS functions.
* Move key/IV length checks closer to usage sites. Also add explicit
checks against EVP_CIPHER_{iv,key}_length().
* Replace two handrolled tls12_record_protection_engaged().
* Improve internal version handling: add handshake fields for our
minimum version, our maximum version and the TLS version negotiated
during the handshake. Convert most of the internal code to use these
version fields.
* Guard against future internal use of TLS1_get_{client,}_version()
macros.
* Remove the internal ssl_downgrade_max_version() function which is no
longer needed.
* Fix checks for memory caps of constraints names. There are internal
caps on the number of name constraints and other names, that the new
name constraints code allocates per cert chain. These limits were
checked too late, making them only partially effective.
* Use EXFLAG_INVALID to handle out of memory and parse errors in
x509v3_cache_extensions().
* Add support for DTLSv1.2 version handling.
* Enable DTLSv1.2 support.
* Add DTLSv1.2 support to openssl s_client/s_server.
* Remove no longer needed read ahead workarounds in the s_client and
s_server.
* Fix a copy-paste error - skid was confused with an akid when
checking for EXFLAG_INVALID. This broke OCSP validation with
certain mirrors.
* Make supported protocols and options for DHE params more prominent
in tls_config_set_protocols.3.
* Avoid a use-after-scope in tls13_cert_add().
* Split TLSv1.3 record protection from record layer.
* Move the TLSv1.3 handshake struct inside the shared handshake
struct.
* Fully initialize rrec in tls12_record_layer_open_record_protected()
to avoid confusing some static analyzers.
* Use tls_set_errorx() on OCSP_basic_verify() failure since the latter
does not set errno.
* Convert openssl(1) x509 to new option handling and do the usual
clean up that goes along with it.
* Add SSL_HANDSHAKE_TLS12 for TLSv1.2 specific handshake data.
* Rename new_cipher to cipher to align naming with keyblock or other
parts of the handshake data.
* Avoid mangled output in BIO_debug_callback().
* Fix client initiated renegotiation by replacing use of s->internal-type
with s->server.
* Move the TLSv1.2 record number increment into the new record layer.
* Move finished and peer finished into the handshake struct.
* Avoid transcript initialization when sending a TLS HelloRequest,
fixing server initiated renegotiation.
* Remove pointless assignment in SSL_get0_alpn_selected().
* Provide EVP_PKEY_new_CMAC_KEY(3).
* Add missing prototype for d2i_DSAPrivateKey_fp(3) to x509.h.
* Add DTLSv1.2 to openssl(1) s_server and s_client protocol message
logging.
* Avoid leaking param->name in x509_verify_param_zero().
* Avoid a leak in an error path in openssl(1) x509.
* Add some error checking to openssl(1) x509.
* When sending an alert in TLSv1.3, only set its error code when no
other error was set previously. Certain clients rely on specific
SSL_R_ error codes to identify that they are dealing with a self
signed cert.
* Switch to the legacy verifier for the stable release.
* Provide SSL_use_certificate_chain_file(3).
* Provide SSL_set_hostflags(3) and SSL_get0_peername(3).
* Provide various DTLSv1.2 specific functions and defines.
* Document meaning of '*' in the genrsa output.
* Updated documentation for SSL_get_shared_ciphers(3).
* Add documentation for SSL_get_finished(3).
* Document EVP_PKEY_new_CMAC_key(3)
* Document SSL_use_certificate_chain_file(3).
* Document SSL_set_hostflags(3) and SSL_get0_peername(3).
* Update SSL_get_version.3 manual for DTLSv.1.2 support.
* Added '--enable-libtls-only' build option, which builds and installs a
statically-linked libtls, skipping libcrypto and libssl. This is useful
for systems that ship with OpenSSL but wish to also package libtls.
3.3.1 - Security fix
* Malformed ASN.1 in a certificate revocation list or a timestamp
response token can lead to a NULL pointer dereference.
Bug fixes
* Move point-on-curve check to set_affine_coordinates to avoid
verifying ECDSA signatures with unchecked public keys.
* Fix SSL_is_server() to behave as documented by re-introducing the
client-specific methods.
* Avoid undefined behavior due to memcpy(NULL, NULL, 0).
* Mark a few more internal static tables const.
3.3.0 - Development release
* Make openssl(1) s_server ignore -4 and -6 for compatibility with
OpenSSL.
* Further cleanup of the DTLS record handling.
* Continue the replacement of the TLSv1.2 record layer by
reimplementing the read side of the TLSv1.2 record handling.
* Replace DTLSv1_enc_data() with TLSv1_1_enc_data().
* Merge d1_{clnt,srvr}.c into ssl_{clnt,srvr}.c.
* When switching from the TLSv1.3 stack to the legacy stack include
a TLS record header. This is necessary if there is more than one
handshake message in the TLS plaintext record.
* Set SO_REUSEADDR on the server socket in the openssl(1) ocsp
command.
* Fix resource handling on error in OCSP_request_add0_id().
* Add const to ssl_ciphers and tls1[23]_sigalgs* to push them into
.data.rel.ro and .rodata, respectively.
* Add a const qualifier to srtp_known_profiles.
* Simplify TLS method by removing the client and server specific
methods internally.
* Avoid casting away const in ssl_ctx_make_profiles().
* Make sure there is enough room for stashing the handshake message
when switching to the legacy TLS stack.
* Avoid explicitly conditioning an assert on DTLS1_VERSION to make
the assert work for newer DTLS versions.
* Merge SSL_ENC_METHOD into SSL_METHOD_INTERNAL.
* Send a host header with OCSP queries to make openssl(1) ocsp
work with some widely used OCSP responders.
* Fix a memory leak in the openssl(1) s_client.
* Add a flag to mark DTLS methods as DTLS to have an easy way to
recognize DTLS methods that avoids inspecting the version number.
* Implement SSL_is_dtls() and use it internally in place of the
SSL_IS_DTLS macro.
* Unbreak DTLS retransmissions for flights that include a CCS.
* Add ability to ocspcheck(8) to parse a port in the specified
OCSP URL.
* Refactor and clean up ocspcheck(8) and add regression tests.
* If x509_verify() fails, ensure that the error is set on both
the x509_verify_ctx() and its store context to make some failures
visible from SSL_get_verify_result().
* Use the X509_STORE_CTX get_issuer() callback from the new X.509
verifier to fix hashed certificate directories.
* Only check BIO_should_read() on read and BIO_should_write() on
write. Previously, BIO_should_write() was also checked after read
and BIO_should_read() after write which could cause stalls in
software that uses the same BIO for read and write.
* In openssl(1) verify, also check for error on the store context
since the return value of X509_verify_cert() is unreliable in
presence of a callback that returns 1 too often.
* Update getentropy on Windows to use Cryptography Next Generation
(CNG). wincrypt is deprecated and no longer works with newer Windows
environments, such as in Windows Store apps.
* Implement auto chain for the TLSv1.3 server since some software
relies on this.
* Handle additional certificate error cases in the new X.509 verifier.
Keep track of the errors encountered if a verify callback tells the
verifier to continue and report them back via the error on the store
context. This mimics the behavior of the old verifier that would
persist the first error encountered while building the chain.
* Report specific failures for "self signed certificates" in a way
compatible with the old verifier since software relies on the
error code.
* Implement key exporter for TLSv1.3.
* Plug a large memory leak in the new verifier caused by calling
X509_policy_check() repeatedly.
* Avoid leaking memory in x509_verify_chain_dup().
* Various documentation improvements, particularly around TLS methods.
3.2.3 - Security fix

response token can lead to a NULL pointer dereference.
