56 suppressing the CA list in Certificate Request messages. The default
57 behaviour has not changed, namely every configured CAs name is included.
58
Andres AGf5bf7182017-03-03 14:09:56 +000059API Changes
60 * The following functions in the AES module have been deprecated and replaced
61 by the functions shown below. The new functions change the return type from
62 void to int to allow returning error codes when using MBEDTLS_AES_ALT,
63 MBEDTLS_AES_DECRYPT_ALT or MBEDTLS_AES_ENCRYPT_ALT.
64 mbedtls_aes_decrypt() -> mbedtls_internal_aes_decrypt()
65 mbedtls_aes_encrypt() -> mbedtls_internal_aes_encrypt()

Simon Butcherb65c2be2017-03-10 18:50:44 +000075 * Add checks to prevent signature forgeries for very large messages while
76 using RSA through the PK module in 64-bit systems. The issue was caused by
77 some data loss when casting a size_t to an unsigned int value in the
78 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
79 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG939954c2016-12-08 17:08:44 +000080 * Fixed potential livelock during the parsing of a CRL in PEM format in
81 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
82 characters after the footer could result in the execution of an infinite
83 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
84 Microsoft.
Janos Follath182013f2016-10-25 10:50:22 +010085 * Removed MD5 from the allowed hash algorithms for CertificateRequest and
86 CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
Simon Butcher0621b1f2017-02-05 16:48:47 +000087 Introduced by interoperability fix for #513.
Janos Follath7dadc2f2017-01-27 16:05:20 +000088 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
89 when verifying the validity of a key on secp224k1. This could be
90 triggered remotely for example with a maliciously constructed certificate
Simon Butcher71e9d582017-02-28 18:47:27 +000091 and potentially could lead to remote code execution on some platforms.
Simon Butcher8b987502017-03-07 12:37:14 +000092 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
93 team. #569 CVE-2017-2784
Janos Follath7dadc2f2017-01-27 16:05:20 +000094
Andres AG703990b2016-10-24 11:23:36 +010095Bugfix
Andres AGd1650662016-12-09 17:26:23 +000096 * Fix output certificate verification flags set by x509_crt_verify_top() when
97 traversing a chain of trusted CA. The issue would cause both flags,
98 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
99 set when the verification conditions are not met regardless of the cause.
100 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcherd57c8f02017-02-02 13:08:37 +0000101 * Fix the redefinition of macro ssl_set_bio to an undefined symbol
102 mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
103 Found by omlib-lin. #673
Andres AGc0db5112016-12-07 15:05:53 +0000104 * Fix unused variable/function compilation warnings in pem.c, x509_crt.c and
105 x509_csr.c that are reported when building mbed TLS with a config.h that
Simon Butchera333b3c2017-02-02 16:17:37 +0000106 does not define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG2196c7f2016-12-15 17:01:16 +0000107 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
108 would compare 64 bits of the record counter instead of 48 bits as indicated
109 in RFC 6347 Section 4.3.1. This could cause the execution of the
110 renegotiation routines at unexpected times when the protocol is DTLS. Found
111 by wariua. #687
Andres AG703990b2016-10-24 11:23:36 +0100112 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing
Andres AG9c94b692016-10-24 14:31:54 +0100113 the input string in PEM format to extract the different components. Found
Andres AG703990b2016-10-24 11:23:36 +0100114 by Eyal Itkin.
Andres Amaya Garcia6a543362017-01-17 23:04:22 +0000115 * Fixed potential arithmetic overflow in mbedtls_ctr_drbg_reseed() that could
116 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
117 * Fixed potential arithmetic overflows in mbedtls_cipher_update() that could
118 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
119 * Fixed potential arithmetic overflow in mbedtls_md2_update() that could
120 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
Andres AG4623d832017-01-18 17:21:03 +0000121 * Fixed potential arithmetic overflow in mbedtls_base64_decode() that could
122 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
Janos Follath87c98072017-02-03 12:36:59 +0000123 * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
124 Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
Andres AG5708dcb2016-12-08 17:19:21 +0000125 * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
126 by missing calls to mbedtls_pem_free() in cases when a
Simon Butcherd02dc142017-02-28 16:36:22 +0000127 MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
128 fix proposed by Guido Vranken. #722
Simon Butcher956c58f2017-03-02 09:18:09 +0000129 * Fixed the templates used to generate project and solution files for Visual
130 Studio 2015 as well as the files themselves, to remove a build warning
131 generated in Visual Studio 2015. Reported by Steve Valliere. #742

Andres AGd1cc7f62017-01-06 13:17:35 +0000134 * Fix 1 byte buffer overflow in mbedtls_mpi_write_string() when the MPI
135 number to write in hexadecimal is negative and requires an odd number of
136 digits. Found and fixed by Guido Vranken.
Simon Butcher81cf88f2017-03-07 19:35:49 +0000137 * Fix unlisted DES configuration dependency in some pkparse test cases. Found
138 by inestlerode. #555

166 scripts, which is also now called by all.sh.
Andres AGf9113192016-09-02 14:06:04 +0100167 * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
168 configure the maximum length of a file path that can be buffered when
169 calling mbedtls_x509_crt_parse_path().
Simon Butcheref8fa012016-10-16 00:44:08 +0100170 * Added a configuration file config-no-entropy.h that configures the subset of

475 * Support for DTLS 1.0 and 1.2 (RFC 6347).
476 * Ability to override core functions from MDx, SHAx, AES and DES modules
477 with custom implementation (eg hardware accelerated), complementing the
478 ability to override the whole module.
479 * New server-side implementation of session tickets that rotate keys to
Manuel Pégourié-Gonnard4d7fbbf2014-10-15 15:40:55 +0200480 preserve forward secrecy, and allows sharing across multiple contexts.
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200481 * Added a concept of X.509 cerificate verification profile that controls
Manuel Pégourié-Gonnarda25ffc32015-06-25 12:01:16 +0200482 which algorithms and key sizes (curves for ECDSA) are acceptable.
483 * Expanded configurability of security parameters in the SSL module with
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200484 mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100485 * Introduced a concept of presets for SSL security-relevant configuration
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200486 parameters.

Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +0200488API Changes
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200489 * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
490 You now need to link to all of them if you use TLS for example.
491 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200492 Some names have been further changed to make them more consistent.
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200493 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200494 provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200495 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200496 mbedtls_cipher_info_t.key_length -> key_bitlen
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200497 mbedtls_cipher_context_t.key_length -> key_bitlen
Manuel Pégourié-Gonnardc34e8dd2015-04-28 21:42:17 +0200498 mbedtls_ecp_curve_info.size -> bit_size
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200499 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
500 * The following _init() functions that could return errors have
Tillmann Karras588ad502015-09-25 04:27:22 +0200501 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200502 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100503 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200504 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

506 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
507 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100508 Note that for mbedtls_ssl_setup(), you need to be done setting up the
509 ssl_config structure before calling it.
Manuel Pégourié-Gonnard9a1a4d62015-05-11 10:35:53 +0200510 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
511 ssl_set_session() and ssl_set_client_transport_id(), plus
512 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
513 (see rename.pl and compat-1.3.h above) and their first argument's type
514 changed from ssl_context to ssl_config.
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200515 * ssl_set_bio() changed signature (contexts merged, order switched, one
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100516 additional callback for read-with-timeout).
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200517 * The following functions have been introduced and must be used in callback
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100518 implementations (SNI, PSK) instead of their *conf counterparts:
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200519 mbedtls_ssl_set_hs_own_cert()
520 mbedtls_ssl_set_hs_ca_chain()
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200521 mbedtls_ssl_set_hs_psk()
522 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200523 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100524 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200525 pointer, parameters reordered).
526 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
527 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100528 * The SSL debug callback gained two new arguments (file name, line number).
Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200529 * Debug modes were removed.
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100530 * mbedtls_ssl_conf_truncated_hmac() now returns void.
531 * mbedtls_memory_buffer_alloc_init() now returns void.
532 * X.509 verification flags are now an uint32_t. Affect the signature of:
533 mbedtls_ssl_get_verify_result()
534 mbedtls_x509_ctr_verify_info()
535 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnard91895852015-06-30 13:34:45 +0200536 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
537 * The following functions changed prototype to avoid an in-out length
Manuel Pégourié-Gonnard0b104b02015-05-14 21:52:40 +0200538 parameter:
Manuel Pégourié-Gonnard8f5fd312015-04-24 14:42:34 +0200539 mbedtls_base64_encode()
540 mbedtls_base64_decode()
Manuel Pégourié-Gonnarddfdcac92015-03-31 11:41:42 +0200541 mbedtls_mpi_write_string()
542 mbedtls_dhm_calc_secret()
Manuel Pégourié-Gonnardb8cfe3f2015-03-31 11:04:45 +0200543 * In the NET module, all "int" and "int *" arguments for file descriptors
Manuel Pégourié-Gonnard1cd10ad2015-06-23 11:07:37 +0200544 changed type to "mbedtls_net_context *".
545 * net_accept() gained new arguments for the size of the client_ip buffer.

547 return void.
548 * ecdsa_write_signature() gained an addtional md_alg argument and
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100549 ecdsa_write_signature_det() was deprecated.
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200550 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
551 * Last argument of x509_crt_check_key_usage() and
552 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000553 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
Manuel Pégourié-Gonnard5b9e5b12015-05-26 17:46:09 +0200554 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
555 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard1b8de572015-05-27 16:49:37 +0200556 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard88bdb0b2015-03-10 14:02:33 +0000557 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
558 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
Manuel Pégourié-Gonnard60c793b2015-06-18 20:52:58 +0200559 length parameter to include the terminating null byte for PEM input.
560 * Signature of mpi_mul_mpi() changed to make the last argument unsigned
Manuel Pégourié-Gonnardf4acfe12014-09-17 10:56:54 +0200561 * calloc() is now used instead of malloc() everywhere. API of platform
562 layer and the memory_buffer_alloc module changed accordingly.
Manuel Pégourié-Gonnardc0d74942015-06-23 12:30:57 +0200563 (Thanks to Mansour Moufid for helping with the replacement.)
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200564 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
565 (support for renegotiation now needs explicit enabling in config.h).
566 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
Manuel Pégourié-Gonnardaff37e52015-05-11 18:11:57 +0200567 in config.h

576 mbedtls_ecp_muladd().
577 * Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions
578 (use generic functions from md.h)
579 * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
580 waiting function.
581 * Removed test DHM parameters from the test certs module.

610 * The default minimum TLS version is now TLS 1.0.
611 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
Manuel Pégourié-Gonnard1028b742015-05-06 17:33:07 +0100612 default ciphersuite list returned by ssl_list_ciphersuites()

Manuel Pégourié-Gonnardcb46fd82015-05-28 17:06:07 +0200616 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
617 enabled in the default configuration, this is only noticeable if using a
618 custom config.h
619 * Default DHM parameters server-side upgraded from 1024 to 2048 bits.
620 * A minimum RSA key size of 2048 bits is now enforced during ceritificate
621 chain verification.

640 mbedtls_ssl_conf_max_version()
Manuel Pégourié-Gonnard1b511f92015-05-06 15:54:23 +0100641 mbedtls_ssl_conf_min_version()
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100642 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
643 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
644 an example implementation, see mbedtls_timing_delay_context and
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200645 mbedtls_timing_set/get_delay().
646 * With UDP sockets, it is no longer necessary to call net_bind() again
Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100647 after a successful net_accept().

Manuel Pégourié-Gonnardda1b4de2014-09-08 17:03:50 +0200858 standard defining how to use SHA-2 with SSL 3.0).
859 * Ciphersuites using RSA-PSK key exchange new require TLS 1.x (the spec is
Manuel Pégourié-Gonnard64938c62014-10-15 21:45:39 +0200860 ambiguous on how to encode some packets with SSL 3.0).

915 use with some ciphersuites and versions (RC4 in all versions, CBC with
Manuel Pégourié-Gonnardd249b7a2014-06-24 11:49:16 +0200916 versions < TLS 1.1).
917 * Very large records using more than 224 bytes of padding were incorrectly
