Gilles Peskine5c324712017-10-17 19:01:38 +02005Security
6 * Fix buffer overflow in RSA-PSS verification when the hash is too
7 large for the key size. Found by Seth Terashima, Qualcomm Product
8 Security Initiative, Qualcomm Technologies Inc.
Gilles Peskined0cd8552017-10-17 19:02:13 +02009 * Fix buffer overflow in RSA-PSS verification when the unmasked
10 data is all zeros.
Gilles Peskine86eece92017-11-23 19:04:39 +010011 * Fix unsafe bounds check in ssl_parse_client_psk_identity() when adding
12 64kB to the address of the SSL buffer wraps around.
Hanno Beckerb658ee62017-09-18 16:07:19 +010013 * Fix a potential heap buffer overflow in mbedtls_ssl_write. When the (by
14 default enabled) maximum fragment length extension is disabled in the
15 config and the application data buffer passed to mbedtls_ssl_write
16 is larger than the internal message buffer (16384 bytes by default), the
17 latter overflows. The exploitability of this issue depends on whether the
18 application layer can be forced into sending such large packets. The issue
19 was independently reported by Tim Nordell via e-mail and by Florin Petriuc
20 and sjorsdewit on GitHub. Fix proposed by Florin Petriuc in #1022. Fixes #707.
Gilles Peskine2f615af2017-11-28 13:34:24 +010021 * Tighten should-be-constant-time memcmp against compiler optimizations.
Andres Amaya Garcia55a52352017-07-05 15:40:17 +010022 * Ensure that buffers are cleared after use if they contain sensitive data.
Andres Amaya Garcia11d2db12017-07-06 17:17:43 +010023 Changes were introduced in multiple places in the library.
Ron Eldor4dc8af72017-09-05 15:34:35 +030024 * Set PEM buffer to zero before freeing it, to avoid decoded private keys
25 being leaked to memory after release.
Janos Follathf3410832017-09-20 15:33:24 +010026 * Fix dhm_check_range() failing to detect trivial subgroups and potentially
27 leaking 1 bit of the private key. Reported by prashantkspatil.
Hanno Beckercf873f72017-10-19 09:13:35 +010028 * Make mbedtls_mpi_read_binary constant-time with respect to
29 the input data. Previously, trailing zero bytes were detected
30 and omitted for the sake of saving memory, but potentially
31 leading to slight timing differences.
32 Reported by Marco Macchetti, Kudelski Group.
Hanno Becker25e39d32017-10-19 10:10:18 +010033 * Wipe stack buffer temporarily holding EC private exponent
34 after keypair generation.
Hanno Beckerb09c5722017-11-20 10:43:35 +000035 * Fix heap corruption in implementation of truncated HMAC extension.
36 When the truncated HMAC extension is enabled and CBC is used,
37 sending a malicious application packet can be used to selectively
38 corrupt 6 bytes on the peer's heap, potentially leading to crash or
39 remote code execution. This can be triggered remotely from either
40 side in both TLS and DTLS.
Gilles Peskine5c324712017-10-17 19:01:38 +020041
Gilles Peskine3099b432017-10-10 20:10:46 +020042Features
43 * Allow comments in test data files.
Gilles Peskineedede442017-12-15 15:01:27 +010044 * The selftest program can execute a subset of the tests based on command
45 line arguments.
Gilles Peskined3949622017-10-27 18:42:32 +020046 * Improve the timing self-tests to be more robust when run on a
47 heavily-loaded machine.
Gilles Peskine3099b432017-10-10 20:10:46 +020048
Andres Amaya Garcia41a38df2017-07-05 13:27:17 +010049Bugfix
Gilles Peskine9745cfd2017-10-19 17:46:14 +020050 * Fix some invalid RSA-PSS signatures with keys of size 8N+1 that were
51 accepted. Generating these signatures required the private key.
Andres Amaya Garcia41a38df2017-07-05 13:27:17 +010052 * Fix ssl_parse_record_header() to silently discard invalid DTLS records
53 as recommended in RFC 6347 Section 4.1.2.7.
Simon Butcher72e9ba22017-09-30 23:51:44 +010054 * Fix memory leak in mbedtls_ssl_set_hostname() when called multiple times.
55 Found by projectgus and jethrogb, #836.
Simon Butcher5d39ace2017-10-02 19:12:54 +010056 * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
Ron Eldorbac9d4d2017-10-03 15:58:26 +030057 * Parse signature algorithm extension when renegotiating. Previously,
58 renegotiated handshakes would only accept signatures using SHA-1
59 regardless of the peer's preferences, or fail if SHA-1 was disabled.
Andres Amaya Garciabc041132016-11-21 15:38:02 +000060 * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
61 dates on leap years with 100 and 400 intervals are handled correctly. Found
62 by Nicholas Wilson. #694
Hanno Becker380aa642017-09-28 16:20:54 +010063 * Fix out-of-memory problem when parsing 4096-bit PKCS8-encrypted RSA keys.
64 Found independently by Florian in the mbed TLS forum and by Mishamax.
65 #878, #1019.
Andres AG705cc652017-02-22 16:23:26 +000066 * Fix unchecked return codes from AES, DES and 3DES functions in
67 pem_aes_decrypt(), pem_des_decrypt() and pem_des3_decrypt() respectively.
68 If a call to one of the functions of the cryptographic primitive modules
69 failed, the error may not be noticed by the function
70 mbedtls_pem_read_buffer() causing it to return invalid values. Found by
71 Guido Vranken. #756
Ron Eldor00cb3af2017-08-22 14:50:14 +030072 * Include configuration file in md.h, to fix compilation warnings.
73 Reported by aaronmdjones in #1001
Hanno Beckera89dbd12017-09-28 14:37:48 +010074 * Correct extraction of signature-type from PK instance in X.509 CRT and CSR
75 writing routines that prevented these functions to work with alternative
76 RSA implementations. Raised by J.B. in the Mbed TLS forum. Fixes #1011.
Hanno Beckerffa7a332017-10-05 09:08:06 +010077 * Don't print X.509 version tag for v1 CRT's, and omit extensions for
78 non-v3 CRT's.
Gilles Peskine25aa8332017-11-28 18:33:50 +010079 * Fix bugs in RSA test suite under MBEDTLS_NO_PLATFORM_ENTROPY. #1023 #1024
Hanno Becker89bf0a72017-05-04 13:39:22 +010080 * Fix net_would_block to avoid modification by errno through fcntl call.
81 Found by nkolban. Fixes #845.
Hanno Becker489f80c2017-10-24 11:56:58 +010082 * Fix handling of handshake messages in mbedtls_ssl_read in case
83 MBEDTLS_SSL_RENEGOTIATION is disabled. Found by erja-gp.
Darryl Green1b052e82017-11-20 17:11:17 +000084 * Add a check for invalid private parameters in ecdsa_sign.
85 Reported by Yolan Romailler.
Gilles Peskinea15486a2017-12-04 17:29:28 +010086 * Fix word size check in in pk.c to not depend on MBEDTLS_HAVE_INT64.
Hanno Beckerfbaeea42017-09-18 11:07:25 +010087 * Add size-checks for record and handshake message content, securing
88 fragile yet non-exploitable code-paths.
Ron Eldor5bd27262017-10-17 18:15:41 +030089 * Fix crash when calling mbedtls_ssl_cache_free() twice. Found by
90 MilenkoMitrovic, #1104
Gilles Peskine3099b432017-10-10 20:10:46 +020091 * Fix mbedtls_timing_alarm(0) on Unix.
Gilles Peskineb29e70b2017-10-16 19:33:06 +020092 * Fix use of uninitialized memory in mbedtls_timing_get_timer when reset=1.
Hanno Beckerffa7a332017-10-05 09:08:06 +010093
94Changes
95 * Extend cert_write example program by options to set the CRT version
96 and the message digest. Further, allow enabling/disabling of authority
97 identifier, subject identifier and basic constraints extensions.

Simon Butchera3050832017-08-10 10:48:33 +0100102 * Fix authentication bypass in SSL/TLS: when authmode is set to optional,
Ron Eldorb5851192017-07-20 00:30:44 +0200103 mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
104 X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
Simon Butchera3050832017-08-10 10:48:33 +0100105 (default: 8) intermediates, even when it was not trusted. This could be
106 triggered remotely from either side. (With authmode set to 'required'
107 (the default), the handshake was correctly aborted).
108 * Reliably zeroize sensitive data after use in AES example applications
Hanno Becker3948a102017-06-27 08:26:53 +0100109 programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
110 Found by Laurent Simon.
Ron Eldorb5851192017-07-20 00:30:44 +0200111
112API Changes
113 * Certificate verification functions now set flags to -1 in case the full
114 chain was not verified due to an internal error (including in the verify
115 callback) or chain length limitations.
Simon Butchera3050832017-08-10 10:48:33 +0100116 * With authmode set to optional, the TLS handshake is now aborted if the
Ron Eldorb5851192017-07-20 00:30:44 +0200117 verification of the peer's certificate failed due to an overlong chain or
Simon Butchera3050832017-08-10 10:48:33 +0100118 a fatal error in the verify callback.

Ron Eldor5ff277e2017-07-20 00:30:44 +0200120Bugfix
Simon Butchera3050832017-08-10 10:48:33 +0100121 * Add a check if iv_len is zero in GCM, and return an error if it is zero.
122 Reported by roberto. #716
123 * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
Ron Eldoree709f42017-01-09 19:27:59 +0200124 to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
125 always be implemented by pthread support. Fix for #696
Simon Butchera3050832017-08-10 10:48:33 +0100126 * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
127 in the case of an error. Found by redplait. #590
Ron Eldora886ce32017-01-12 14:50:50 +0200128 * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
129 Reported and fix suggested by guidovranken in #740
Andres AG0ff660e2017-02-10 14:39:58 +0000130 * Fix a potential integer overflow in the version verification for DER
131 encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
132 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
133 KNOX Security, Samsung Research America
Andres AGb322be52017-02-17 13:54:43 +0000134 * Fix a potential integer overflow in the version verification for DER
135 encoded X509 certificates. The overflow would enable maliciously
136 constructed certificates to bypass the certificate verification check.
137 * Fix potential integer overflow in the version verification for DER
138 encoded X509 CSRs. The overflow would enable maliciously constructed CSRs
139 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
140 KNOX Security, Samsung Research America

Hanno Becker88647ac2017-06-09 11:30:33 +0100150 * Fixed unlimited overread of heap-based buffer in mbedtls_ssl_read().
151 The issue could only happen client-side with renegotiation enabled.
152 Could result in DoS (application crash) or information leak
153 (if the application layer sent data read from mbedtls_ssl_read()
154 back to the server or to a third party). Can be triggered remotely.
Janos Follath4477bca2017-03-23 10:41:56 +0000155 * Add exponent blinding to RSA private operations as a countermeasure
156 against side-channel attacks like the cache attack described in
157 https://arxiv.org/abs/1702.08719v2.
158 Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,
159 Clémentine Maurice and Stefan Mangard.

164 certificate verification. SHA-1 can be turned back on with a compile-time
165 option if needed.
Gilles Peskine39e29812017-05-16 17:53:03 +0200166 * Fixed offset in FALLBACK_SCSV parsing that caused TLS server to fail to
167 detect it sometimes. Reported by Hugo Leisink. #810
Manuel Pégourié-Gonnard230ee312017-05-11 12:49:51 +0200168 * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
169 potential Bleichenbacher/BERserk-style attack.

180 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
Hanno Becker58897fb2017-07-27 15:10:21 +0100181 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
Janos Follath3fb1cc32017-06-16 14:04:08 +0100182 reflect bad EC curves within verification result.
183 * Fix bug that caused the modular inversion function to accept the invalid
184 modulus 1 and therefore to hang. Found by blaufish. #641.
185 * Fix incorrect sign computation in modular exponentiation when the base is
186 a negative MPI. Previously the result was always negative. Found by Guido
187 Vranken.
188 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
189 that was triggered uppon reading an empty line. Found by Guido Vranken.

Simon Butchere4b3df52017-02-26 02:01:22 +0000199 * Add checks to prevent signature forgeries for very large messages while
200 using RSA through the PK module in 64-bit systems. The issue was caused by
201 some data loss when casting a size_t to an unsigned int value in the
202 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
203 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG7cd7cf02016-12-08 17:08:44 +0000204 * Fixed potential livelock during the parsing of a CRL in PEM format in
205 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
206 characters after the footer could result in the execution of an infinite
207 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
208 Microsoft.
Janos Follath8dbb35a2017-01-27 16:05:20 +0000209 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
210 when verifying the validity of a key on secp224k1. This could be
211 triggered remotely for example with a maliciously constructed certificate
Simon Butcher3ea1af22017-02-28 18:47:27 +0000212 and potentially could lead to remote code execution on some platforms.
Simon Butcherbd6882b2017-03-07 12:37:14 +0000213 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos

Andres AG8136e822016-12-09 17:26:23 +0000217 * Fix output certificate verification flags set by x509_crt_verify_top() when
218 traversing a chain of trusted CA. The issue would cause both flags,
219 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
220 set when the verification conditions are not met regardless of the cause.
221 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcher0f862942017-02-02 13:08:37 +0000222 * Fix the redefinition of macro ssl_set_bio to an undefined symbol

Andres AG480a9582016-12-07 15:05:53 +0000225 * Fix unused variable/function compilation warnings in pem.c and x509_csr.c
226 that are reported when building mbed TLS with a config.h that does not
Simon Butcheref3d4e42017-02-02 16:36:59 +0000227 define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG8efc7692016-12-15 17:01:16 +0000228 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
229 would compare 64 bits of the record counter instead of 48 bits as indicated
230 in RFC 6347 Section 4.3.1. This could cause the execution of the
231 renegotiation routines at unexpected times when the protocol is DTLS. Found
232 by wariua. #687
Andres AGc6559722016-10-24 11:23:36 +0100233 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

Simon Butcherd69f14b2015-09-11 20:00:20 +0100464Changes
465 * Made X509 profile pointer const in mbedtls_ssl_conf_cert_profile() to allow
466 use of mbedtls_x509_crt_profile_next. (found by NWilson)
Manuel Pégourié-Gonnard14c25742015-09-08 15:12:45 +0200467 * When a client initiates a reconnect from the same port as a live
468 connection, if cookie verification is available
469 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
470 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
471 detected and mbedtls_ssl_read() will return
472 MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a new
473 handshake with the same context. (See RFC 6347 section 4.2.8.)

544 You now need to link to all of them if you use TLS for example.
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +0200545 * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
Manuel Pégourié-Gonnard6e088f92015-05-06 17:53:08 +0100546 Some names have been further changed to make them more consistent.

Manuel Pégourié-Gonnard898e0aa2015-06-18 15:28:12 +0200549 * Renamings of fields inside structures, not covered by the previous list:
Manuel Pégourié-Gonnard797f48a2015-06-18 15:45:05 +0200550 mbedtls_cipher_info_t.key_length -> key_bitlen

Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200554 * The following _init() functions that could return errors have
Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200555 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200556 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200557 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200558 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

561 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Tillmann Karras588ad502015-09-25 04:27:22 +0200562 Note that for mbedtls_ssl_setup(), you need to be done setting up the
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200563 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100564 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),

573 mbedtls_ssl_set_hs_own_cert()
574 mbedtls_ssl_set_hs_ca_chain()
575 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200576 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100577 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200578 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100579 pointer, parameters reordered).
Manuel Pégourié-Gonnard866eb472015-05-25 19:41:37 +0200580 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
581 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnardfd474232015-06-23 16:34:24 +0200582 * The SSL debug callback gained two new arguments (file name, line number).
583 * Debug modes were removed.

Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100591 * The following functions changed prototype to avoid an in-out length
592 parameter:
593 mbedtls_base64_encode()
594 mbedtls_base64_decode()
595 mbedtls_mpi_write_string()
596 mbedtls_dhm_calc_secret()

Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100607 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
608 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
609 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100610 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200611 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
612 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
613 length parameter to include the terminating null byte for PEM input.
Manuel Pégourié-Gonnard35f1d7f2015-03-19 12:42:40 +0000614 * Signature of mpi_mul_mpi() changed to make the last argument unsigned

Paul Bakkerb6ecaf52011-04-19 14:29:23 +00001851Features
1852 * Added additional Cipher Block Modes to symmetric ciphers
1853 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +01001854 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +00001855 * Functions requiring File System functions can now be disabled
1856 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001857 * A error_strerror function() has been added to translate between
1858 error codes and their description.
Paul Bakker2f5947e2011-05-18 15:47:11 +00001859 * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
1860 functions.

Paul Bakker23986e52011-04-24 08:57:21 +00001863Changes
1864 * Major argument / variable rewrite. Introduced use of size_t
1865 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001866 better unsigned / signed use. Renamed internal bigint types
1867 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +00001868 * mpi_init() and mpi_free() now only accept a single MPI
1869 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +00001870 * The error codes have been remapped and combining error codes
1871 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001872 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001873 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1874 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001875 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1876 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1877 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1878 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001879 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
1880 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
Paul Bakkera35aa542013-03-06 17:06:21 +01001881 POLARSSL_ERR_NET_TRY_AGAIN

Hanno Becker58897fb2017-07-27 15:10:21 +01001895 * x509parse_key() (and as a consequence x509parse_keyfile())
Paul Bakker98675492011-03-26 13:17:12 +00001896 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001897 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001898
