1 mbed TLS ChangeLog (Sorted per branch, date)
3 = mbed TLS 2.4.0 branch released 2016-10-17
6 * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
7 with RFC-5116 and could lead to session key recovery in very long TLS
8 sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in
9 TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic.
10 https://eprint.iacr.org/2016/475.pdf
11 * Fixed potential stack corruption in mbedtls_x509write_crt_der() and
12 mbedtls_x509write_csr_der() when the signature is copied to the buffer
13 without checking whether there is enough space in the destination. The
14 issue cannot be triggered remotely. Found by Jethro Beekman.
17 * Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128, as defined by
18 NIST SP 800-38B, RFC-4493 and RFC-4615.
19 * Added hardware entropy selftest to verify that the hardware entropy source
20 is functioning correctly.
21 * Added a script to print build environment info for diagnostic use in test
22 scripts, which is also now called by all.sh.
23 * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
24 configure the maximum length of a file path that can be buffered when
25 calling mbedtls_x509_crt_parse_path().
26 * Added a configuration file config-no-entropy.h that configures the subset of
27 library features that do not require an entropy source.
28 * Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This allows users
29 to configure the minimum number of bytes for entropy sources using the
30 mbedtls_hardware_poll() function.
33 * Fix for platform time abstraction to avoid dependency issues where a build
34 may need time but not the standard C library abstraction, and added
35 configuration consistency checks to check_config.h
36 * Fix dependency issue in Makefile to allow parallel builds.
37 * Fix incorrect handling of block lengths in crypt_and_hash.c sample program,
38 when GCM is used. Found by udf2457. #441
39 * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't
40 enabled unless others were also present. Found by David Fernandez. #428
41 * Fix for out-of-tree builds using CMake. Found by jwurzer, and fix based on
42 a contribution from Tobias Tangemann. #541
43 * Fixed cert_app.c sample program for debug output and for use when no root
44 certificates are provided.
45 * Fix conditional statement that would cause a 1 byte overread in
46 mbedtls_asn1_get_int(). Found and fixed by Guido Vranken. #599
47 * Fixed pthread implementation to avoid unintended double initialisations
48 and double frees. Found by Niklas Amnebratt.
49 * Fixed the sample applications gen_key.c, cert_req.c and cert_write.c for
50 builds where the configuration MBEDTLS_PEM_WRITE_C is not defined. Found
52 * Fix mbedtls_x509_get_sig() to update the ASN1 type in the mbedtls_x509_buf
53 data structure until after error checks are successful. Found by
55 * Fix documentation and implementation missmatch for function arguments of
56 mbedtls_gcm_finish(). Found by cmiatpaar. #602
57 * Guarantee that P>Q at RSA key generation. Found by inestlerode. #558
58 * Fix potential byte overread when verifying malformed SERVER_HELLO in
59 ssl_parse_hello_verify_request() for DTLS. Found by Guido Vranken.
60 * Fix check for validity of date when parsing in mbedtls_x509_get_time().
61 Found by subramanyam-c. #626
62 * Fix compatibility issue with Internet Explorer client authentication,
63 where the limited hash choices prevented the client from sending its
64 certificate. Found by teumas. #513
65 * Fix compilation without MBEDTLS_SELF_TEST enabled.
68 * Extended test coverage of special cases, and added new timing test suite.
69 * Removed self-tests from the basic-built-test.sh script, and added all
70 missing self-tests to the test suites, to ensure self-tests are only
72 * Added support for 3 and 4 byte lengths to mbedtls_asn1_write_len().
73 * Added support for a Yotta specific configuration file -
74 through the symbol YOTTA_CFG_MBEDTLS_TARGET_CONFIG_FILE.
75 * Added optimization for code space for X.509/OID based on configured
76 features. Contributed by Aviv Palivoda.
77 * Renamed source file library/net.c to library/net_sockets.c to avoid
78 naming collision in projects which also have files with the common name
79 net.c. For consistency, the corresponding header file, net.h, is marked as
80 deprecated, and its contents moved to net_sockets.h.
81 * Changed the strategy for X.509 certificate parsing and validation, to no
82 longer disregard certificates with unrecognised fields.
84 = mbed TLS 2.3.0 branch released 2016-06-28
87 * Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt
88 required by PKCS1 v2.2
89 * Fix potential integer overflow to buffer overflow in
90 mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt
91 (not triggerable remotely in (D)TLS).
92 * Fix a potential integer underflow to buffer overread in
93 mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in
97 * Support for platform abstraction of the standard C library time()
101 * Fix bug in mbedtls_mpi_add_mpi() that caused wrong results when the three
102 arguments where the same (in-place doubling). Found and fixed by Janos
104 * Fix potential build failures related to the 'apidoc' target, introduced
105 in the previous patch release. Found by Robert Scheck. #390 #391
106 * Fix issue in Makefile that prevented building using armar. #386
107 * Fix memory leak that occured only when ECJPAKE was enabled and ECDHE and
108 ECDSA was disabled in config.h . The leak didn't occur by default.
109 * Fix an issue that caused valid certificates to be rejected whenever an
110 expired or not yet valid certificate was parsed before a valid certificate
111 in the trusted certificate list.
112 * Fix bug in mbedtls_x509_crt_parse that caused trailing extra data in the
113 buffer after DER certificates to be included in the raw representation.
114 * Fix issue that caused a hang when generating RSA keys of odd bitlength
115 * Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made null pointer
116 dereference possible.
117 * Fix issue that caused a crash if invalid curves were passed to
118 mbedtls_ssl_conf_curves. #373
119 * Fix issue in ssl_fork_server which was preventing it from functioning. #429
120 * Fix memory leaks in test framework
121 * Fix test in ssl-opt.sh that does not run properly with valgrind
122 * Fix unchecked calls to mmbedtls_md_setup(). Fix by Brian Murray. #502
125 * On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5,
126 don't use the optimized assembly for bignum multiplication. This removes
127 the need to pass -fomit-frame-pointer to avoid a build error with -O0.
128 * Disabled SSLv3 in the default configuration.
129 * Optimized mbedtls_mpi_zeroize() for MPI integer size. (Fix by Alexey
131 * Fix non-compliance server extension handling. Extensions for SSLv3 are now
132 ignored, as required by RFC6101.
134 = mbed TLS 2.2.1 released 2016-01-05
137 * Fix potential double free when mbedtls_asn1_store_named_data() fails to
138 allocate memory. Only used for certificate generation, not triggerable
139 remotely in SSL/TLS. Found by Rafał Przywara. #367
140 * Disable MD5 handshake signatures in TLS 1.2 by default to prevent the
141 SLOTH attack on TLS 1.2 server authentication (other attacks from the
142 SLOTH paper do not apply to any version of mbed TLS or PolarSSL).
143 https://www.mitls.org/pages/attacks/SLOTH
146 * Fix over-restrictive length limit in GCM. Found by Andreas-N. #362
147 * Fix bug in certificate validation that caused valid chains to be rejected
148 when the first intermediate certificate has pathLenConstraint=0. Found by
149 Nicholas Wilson. Introduced in mbed TLS 2.2.0. #280
150 * Removed potential leak in mbedtls_rsa_rsassa_pkcs1_v15_sign(), found by
151 JayaraghavendranK. #372
152 * Fix suboptimal handling of unexpected records that caused interop issues
153 with some peers over unreliable links. Avoid dropping an entire DTLS
154 datagram if a single record in a datagram is unexpected, instead only
155 drop the record and look at subsequent records (if any are present) in
156 the same datagram. Found by jeannotlapin. #345
158 = mbed TLS 2.2.0 released 2015-11-04
161 * Fix potential double free if mbedtls_ssl_conf_psk() is called more than
162 once and some allocation fails. Cannot be forced remotely. Found by Guido
164 * Fix potential heap corruption on Windows when
165 mbedtls_x509_crt_parse_path() is passed a path longer than 2GB. Cannot be
166 triggered remotely. Found by Guido Vranken, Intelworks.
167 * Fix potential buffer overflow in some asn1_write_xxx() functions.
168 Cannot be triggered remotely unless you create X.509 certificates based
169 on untrusted input or write keys of untrusted origin. Found by Guido
171 * The X509 max_pathlen constraint was not enforced on intermediate
172 certificates. Found by Nicholas Wilson, fix and tests provided by
173 Janos Follath. #280 and #319
176 * Experimental support for EC J-PAKE as defined in Thread 1.0.0.
177 Disabled by default as the specification might still change.
178 * Added a key extraction callback to accees the master secret and key
179 block. (Potential uses include EAP-TLS and Thread.)
182 * Self-signed certificates were not excluded from pathlen counting,
183 resulting in some valid X.509 being incorrectly rejected. Found and fix
184 provided by Janos Follath. #319
185 * Fix build error with configurations where ECDHE-PSK is the only key
186 exchange. Found and fix provided by Chris Hammond. #270
187 * Fix build error with configurations where RSA, RSA-PSK, ECDH-RSA or
188 ECHD-ECDSA if the only key exchange. Multiple reports. #310
189 * Fixed a bug causing some handshakes to fail due to some non-fatal alerts
190 not being properly ignored. Found by mancha and Kasom Koht-arsa, #308
191 * mbedtls_x509_crt_verify(_with_profile)() now also checks the key type and
192 size/curve against the profile. Before that, there was no way to set a
193 minimum key size for end-entity certificates with RSA keys. Found by
194 Matthew Page of Scannex Electronics Ltd.
195 * Fix failures in MPI on Sparc(64) due to use of bad assembly code.
196 Found by Kurt Danielson. #292
197 * Fix typo in name of the extKeyUsage OID. Found by inestlerode, #314
198 * Fix bug in ASN.1 encoding of booleans that caused generated CA
199 certificates to be rejected by some applications, including OS X
200 Keychain. Found and fixed by Jonathan Leroy, Inikup.
203 * Improved performance of mbedtls_ecp_muladd() when one of the scalars is 1
206 = mbed TLS 2.1.2 released 2015-10-06
209 * Added fix for CVE-2015-5291 to prevent heap corruption due to buffer
210 overflow of the hostname or session ticket. Found by Guido Vranken,
212 * Fix potential double-free if mbedtls_ssl_set_hs_psk() is called more than
213 once in the same handhake and mbedtls_ssl_conf_psk() was used.
214 Found and patch provided by Guido Vranken, Intelworks. Cannot be forced
216 * Fix stack buffer overflow in pkcs12 decryption (used by
217 mbedtls_pk_parse_key(file)() when the password is > 129 bytes.
218 Found by Guido Vranken, Intelworks. Not triggerable remotely.
219 * Fix potential buffer overflow in mbedtls_mpi_read_string().
220 Found by Guido Vranken, Intelworks. Not exploitable remotely in the context
221 of TLS, but might be in other uses. On 32 bit machines, requires reading a
222 string of close to or larger than 1GB to exploit; on 64 bit machines, would
223 require reading a string of close to or larger than 2^62 bytes.
224 * Fix potential random memory allocation in mbedtls_pem_read_buffer()
225 on crafted PEM input data. Found and fix provided by Guido Vranken,
226 Intelworks. Not triggerable remotely in TLS. Triggerable remotely if you
227 accept PEM data from an untrusted source.
228 * Fix possible heap buffer overflow in base64_encoded() when the input
229 buffer is 512MB or larger on 32-bit platforms. Found by Guido Vranken,
230 Intelworks. Not trigerrable remotely in TLS.
231 * Fix potential double-free if mbedtls_conf_psk() is called repeatedly on
232 the same mbedtls_ssl_config object and memory allocation fails. Found by
233 Guido Vranken, Intelworks. Cannot be forced remotely.
234 * Fix potential heap buffer overflow in servers that perform client
235 authentication against a crafted CA cert. Cannot be triggered remotely
236 unless you allow third parties to pick trust CAs for client auth.
237 Found by Guido Vranken, Intelworks.
240 * Fix compile error in net.c with musl libc. Found and patch provided by
242 * Fix macroization of 'inline' keyword when building as C++. (#279)
245 * Added checking of hostname length in mbedtls_ssl_set_hostname() to ensure
246 domain names are compliant with RFC 1035.
247 * Fixed paths for check_config.h in example config files. (Found by bachp)
250 = mbed TLS 2.1.1 released 2015-09-17
253 * Add countermeasure against Lenstra's RSA-CRT attack for PKCS#1 v1.5
254 signatures. (Found by Florian Weimer, Red Hat.)
255 https://securityblog.redhat.com/2015/09/02/factoring-rsa-keys-with-tls-perfect-forward-secrecy/
256 * Fix possible client-side NULL pointer dereference (read) when the client
257 tries to continue the handshake after it failed (a misuse of the API).
258 (Found and patch provided by Fabian Foerg, Gotham Digital Science using
262 * Fix warning when using a 64bit platform. (found by embedthis) (#275)
263 * Fix off-by-one error in parsing Supported Point Format extension that
264 caused some handshakes to fail.
267 * Made X509 profile pointer const in mbedtls_ssl_conf_cert_profile() to allow
268 use of mbedtls_x509_crt_profile_next. (found by NWilson)
269 * When a client initiates a reconnect from the same port as a live
270 connection, if cookie verification is available
271 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
272 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
273 detected and mbedtls_ssl_read() will return
274 MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a new
275 handshake with the same context. (See RFC 6347 section 4.2.8.)
277 = mbed TLS 2.1.0 released 2015-09-04
280 * Added support for yotta as a build system.
281 * Primary open source license changed to Apache 2.0 license.

300 * Fix link error when building shared libraries for Windows with make.
301 * Fix error when loading libmbedtls.so.
302 * Fix bug in mbedtls_ssl_conf_default() that caused the default preset to
303 be always used (found by dcb314) (#235)
304 * Fix bug in mbedtls_rsa_public() and mbedtls_rsa_private() that could
305 result trying to unlock an unlocked mutex on invalid input (found by
306 Fredrik Axelsson) (#257)
307 * Fix -Wshadow warnings (found by hnrkp) (#240)
308 * Fix memory corruption on client with overlong PSK identity, around
309 SSL_MAX_CONTENT_LEN or higher - not triggerrable remotely (found by
310 Aleksandrs Saveljevs) (#238)
311 * Fix unused function warning when using MBEDTLS_MDx_ALT or
312 MBEDTLS_SHAxxx_ALT (found by Henrik) (#239)
313 * Fix memory corruption in pkey programs (found by yankuncheng) (#210)
316 * The PEM parser now accepts a trailing space at end of lines (#226).

318 end of the default config.h by defining MBEDTLS_USER_CONFIG_FILE on the
319 compiler's command line.
320 * When verifying a certificate chain, if an intermediate certificate is
321 trusted, no later cert is checked. (suggested by hannes-landeholm)
323 * Prepend a "thread identifier" to debug messages (issue pointed out by
324 Hugo Leisink) (#210).
325 * Add mbedtls_ssl_get_max_frag_len() to query the current maximum fragment
328 = mbed TLS 2.0.0 released 2015-07-13
331 * Support for DTLS 1.0 and 1.2 (RFC 6347).
332 * Ability to override core functions from MDx, SHAx, AES and DES modules
333 with custom implementation (eg hardware accelerated), complementing the
334 ability to override the whole module.
335 * New server-side implementation of session tickets that rotate keys to
336 preserve forward secrecy, and allows sharing across multiple contexts.
337 * Added a concept of X.509 cerificate verification profile that controls
338 which algorithms and key sizes (curves for ECDSA) are acceptable.
339 * Expanded configurability of security parameters in the SSL module with
340 mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
341 * Introduced a concept of presets for SSL security-relevant configuration
345 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
346 You now need to link to all of them if you use TLS for example.
347 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
348 Some names have been further changed to make them more consistent.
349 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
350 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
351 * Renamings of fields inside structures, not covered by the previous list:
352 mbedtls_cipher_info_t.key_length -> key_bitlen
353 mbedtls_cipher_context_t.key_length -> key_bitlen
354 mbedtls_ecp_curve_info.size -> bit_size
355 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
356 * The following _init() functions that could return errors have
357 been split into an _init() that returns void and another function that
358 should generally be the first function called on this context after init:
359 mbedtls_ssl_init() -> mbedtls_ssl_setup()
360 mbedtls_ccm_init() -> mbedtls_ccm_setkey()
361 mbedtls_gcm_init() -> mbedtls_gcm_setkey()
362 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
363 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
364 Note that for mbedtls_ssl_setup(), you need to be done setting up the
365 ssl_config structure before calling it.
366 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
367 ssl_set_session() and ssl_set_client_transport_id(), plus
368 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
369 (see rename.pl and compat-1.3.h above) and their first argument's type
370 changed from ssl_context to ssl_config.
371 * ssl_set_bio() changed signature (contexts merged, order switched, one
372 additional callback for read-with-timeout).
373 * The following functions have been introduced and must be used in callback
374 implementations (SNI, PSK) instead of their *conf counterparts:
375 mbedtls_ssl_set_hs_own_cert()
376 mbedtls_ssl_set_hs_ca_chain()
377 mbedtls_ssl_set_hs_psk()
378 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
379 using mbedtls_ssl_set_hostname().
380 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
381 pointer, parameters reordered).
382 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
383 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
384 * The SSL debug callback gained two new arguments (file name, line number).
385 * Debug modes were removed.
386 * mbedtls_ssl_conf_truncated_hmac() now returns void.
387 * mbedtls_memory_buffer_alloc_init() now returns void.
388 * X.509 verification flags are now an uint32_t. Affect the signature of:
389 mbedtls_ssl_get_verify_result()
390 mbedtls_x509_ctr_verify_info()
391 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
392 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
393 * The following functions changed prototype to avoid an in-out length
395 mbedtls_base64_encode()
396 mbedtls_base64_decode()
397 mbedtls_mpi_write_string()
398 mbedtls_dhm_calc_secret()
399 * In the NET module, all "int" and "int *" arguments for file descriptors
400 changed type to "mbedtls_net_context *".
401 * net_accept() gained new arguments for the size of the client_ip buffer.
402 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
404 * ecdsa_write_signature() gained an addtional md_alg argument and
405 ecdsa_write_signature_det() was deprecated.
406 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
407 * Last argument of x509_crt_check_key_usage() and
408 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
409 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
410 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
411 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
412 strings; use the new *_len variables instead of strlen().
413 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
414 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
415 length parameter to include the terminating null byte for PEM input.
416 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
417 * calloc() is now used instead of malloc() everywhere. API of platform
418 layer and the memory_buffer_alloc module changed accordingly.
419 (Thanks to Mansour Moufid for helping with the replacement.)
420 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
421 (support for renegotiation now needs explicit enabling in config.h).
422 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
424 * net_connect() and net_bind() have a new 'proto' argument to choose
425 between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
426 Their 'port' argument type is changed to a string.
427 * Some constness fixes
430 * Removed mbedtls_ecp_group_read_string(). Only named groups are supported.
431 * Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use
432 mbedtls_ecp_muladd().
433 * Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions
434 (use generic functions from md.h)
435 * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
437 * Removed test DHM parameters from the test certs module.
438 * Removed the PBKDF2 module (use PKCS5).
439 * Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
440 * Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
441 * Removed openssl.h (very partial OpenSSL compatibility layer).
442 * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
443 * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
444 been removed (compiler is required to support 32-bit operations).
445 * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
446 * Removed test program o_p_test, the script compat.sh does more.
447 * Removed test program ssl_test, superseded by ssl-opt.sh.
448 * Removed helper script active-config.pl
451 * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
452 argument (allowing memory savings if HMAC is not used)
454 Semi-API changes (technically public, morally private)
455 * Renamed a few headers to include _internal in the name. Those headers are
456 not supposed to be included by users.
