Ron Eldor5ff277e2017-07-20 00:30:44 +02003= mbed TLS 2.1.9 branch released xxxx-xx-xx
4
Ron Eldorb5851192017-07-20 00:30:44 +02005Security
6 * Fix authentication bypass in SSL/TLS: when auth_mode is set to optional,
7 mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
8 X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
9 (default: 8) intermediates, even when it was not trusted. Could be
10 triggered remotely on both sides. (With auth_mode set to required
11 (default), the handshake was correctly aborted.)
Hanno Becker3948a102017-06-27 08:26:53 +010012 * Realiably zeroize sensitive data after use in AES example applications
13 programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
14 Found by Laurent Simon.
Ron Eldorb5851192017-07-20 00:30:44 +020015
16API Changes
17 * Certificate verification functions now set flags to -1 in case the full
18 chain was not verified due to an internal error (including in the verify
19 callback) or chain length limitations.
20 * With authmode set to optional, handshake is now aborted if the
21 verification of the peer's certificate failed due to an overlong chain or
22 a fatal error in the vrfy callback.
23
Ron Eldor5ff277e2017-07-20 00:30:44 +020024Bugfix
25 * Add a check if iv_len is zero, and return an error if it is zero. reported
26 by roberto. #716
Ron Eldoree709f42017-01-09 19:27:59 +020027 * Replace preproccessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
28 to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
29 always be implemented by pthread support. Fix for #696
Ron Eldor0fb3e0a2017-01-09 15:09:16 +020030 * Fix resource leak on windows platform, in mbedtls_x509_crt_parse_path.
31 In case of failure, when an error occures, goto cleanup.
32 Found by redplait #590
Ron Eldora886ce32017-01-12 14:50:50 +020033 * Add MBEDTLS_MPI_CHK to check for error value of mbedtls_mpi_fill_random.
34 Reported and fix suggested by guidovranken in #740
Andres AG0ff660e2017-02-10 14:39:58 +000035 * Fix a potential integer overflow in the version verification for DER
36 encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
37 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
38 KNOX Security, Samsung Research America
Andres AGb322be52017-02-17 13:54:43 +000039 * Fix a potential integer overflow in the version verification for DER
40 encoded X509 certificates. The overflow would enable maliciously
41 constructed certificates to bypass the certificate verification check.
42 * Fix potential integer overflow in the version verification for DER
43 encoded X509 CSRs. The overflow would enable maliciously constructed CSRs
44 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
45 KNOX Security, Samsung Research America

Hanno Becker88647ac2017-06-09 11:30:33 +010055 * Fixed unlimited overread of heap-based buffer in mbedtls_ssl_read().
56 The issue could only happen client-side with renegotiation enabled.
57 Could result in DoS (application crash) or information leak
58 (if the application layer sent data read from mbedtls_ssl_read()
59 back to the server or to a third party). Can be triggered remotely.
Janos Follath4477bca2017-03-23 10:41:56 +000060 * Add exponent blinding to RSA private operations as a countermeasure
61 against side-channel attacks like the cache attack described in
62 https://arxiv.org/abs/1702.08719v2.
63 Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,
64 Clémentine Maurice and Stefan Mangard.
Gilles Peskine8877ec22017-03-23 14:37:37 +010065 * Wipe stack buffers in RSA private key operations
Janos Follath3fb1cc32017-06-16 14:04:08 +010066 (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt). Found by Laurent
67 Simon.
Gilles Peskine7344e1b2017-05-12 13:16:40 +020068 * Removed SHA-1 and RIPEMD-160 from the default hash algorithms for
69 certificate verification. SHA-1 can be turned back on with a compile-time
70 option if needed.
Gilles Peskine39e29812017-05-16 17:53:03 +020071 * Fixed offset in FALLBACK_SCSV parsing that caused TLS server to fail to
72 detect it sometimes. Reported by Hugo Leisink. #810
Manuel Pégourié-Gonnard230ee312017-05-11 12:49:51 +020073 * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
74 potential Bleichenbacher/BERserk-style attack.
Janos Follath4477bca2017-03-23 10:41:56 +000075
Simon Butcher93d0f4b2017-05-13 23:00:05 +010076Bugfix

78 recent versions of the library. Found by Kyle Keen.
Janos Follath3fb1cc32017-06-16 14:04:08 +010079 * Fixed issue in the Threading module that prevented mutexes from
80 initialising. Found by sznaider. #667 #843
Hanno Beckeraa8a2bd2017-04-28 17:15:26 +010081 * Fix insufficient support for signature-hash-algorithm extension,
82 resulting in compatibility problems with Chrome. Found by hfloyrd. #823
Hanno Beckera3929ba2017-05-08 16:31:14 +010083 * Accept empty trusted CA chain in authentication mode
Janos Follath3fb1cc32017-06-16 14:04:08 +010084 MBEDTLS_SSL_VERIFY_OPTIONAL. Found by jethrogb. #864
85 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
Hanno Becker58897fb2017-07-27 15:10:21 +010086 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
Janos Follath3fb1cc32017-06-16 14:04:08 +010087 reflect bad EC curves within verification result.
88 * Fix bug that caused the modular inversion function to accept the invalid
89 modulus 1 and therefore to hang. Found by blaufish. #641.
90 * Fix incorrect sign computation in modular exponentiation when the base is
91 a negative MPI. Previously the result was always negative. Found by Guido
92 Vranken.
93 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
94 that was triggered uppon reading an empty line. Found by Guido Vranken.
Simon Butcher93d0f4b2017-05-13 23:00:05 +010095
Janos Follath5ad67892017-03-10 11:31:41 +000096Changes
97 * Clarify ECDSA documentation and improve the sample code to avoid
Janos Follath3fb1cc32017-06-16 14:04:08 +010098 misunderstanding and potentially dangerous use of the API. Pointed out

Simon Butchere4b3df52017-02-26 02:01:22 +0000104 * Add checks to prevent signature forgeries for very large messages while
105 using RSA through the PK module in 64-bit systems. The issue was caused by
106 some data loss when casting a size_t to an unsigned int value in the
107 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
108 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG7cd7cf02016-12-08 17:08:44 +0000109 * Fixed potential livelock during the parsing of a CRL in PEM format in
110 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
111 characters after the footer could result in the execution of an infinite
112 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
113 Microsoft.
Janos Follath8dbb35a2017-01-27 16:05:20 +0000114 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
115 when verifying the validity of a key on secp224k1. This could be
116 triggered remotely for example with a maliciously constructed certificate
Simon Butcher3ea1af22017-02-28 18:47:27 +0000117 and potentially could lead to remote code execution on some platforms.
Simon Butcherbd6882b2017-03-07 12:37:14 +0000118 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
119 team. #569 CVE-2017-2784

Andres AG8136e822016-12-09 17:26:23 +0000122 * Fix output certificate verification flags set by x509_crt_verify_top() when
123 traversing a chain of trusted CA. The issue would cause both flags,
124 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
125 set when the verification conditions are not met regardless of the cause.
126 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcher0f862942017-02-02 13:08:37 +0000127 * Fix the redefinition of macro ssl_set_bio to an undefined symbol

131 that are reported when building mbed TLS with a config.h that does not
Simon Butcheref3d4e42017-02-02 16:36:59 +0000132 define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG8efc7692016-12-15 17:01:16 +0000133 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
134 would compare 64 bits of the record counter instead of 48 bits as indicated
135 in RFC 6347 Section 4.3.1. This could cause the execution of the
136 renegotiation routines at unexpected times when the protocol is DTLS. Found
137 by wariua. #687
Andres AGc6559722016-10-24 11:23:36 +0100138 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

142 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
143 * Fixed potential arithmetic overflows in mbedtls_cipher_update() that could
144 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
145 * Fixed potential arithmetic overflow in mbedtls_md2_update() that could
146 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
Andres AGd00d3e22017-01-18 17:21:03 +0000147 * Fixed potential arithmetic overflow in mbedtls_base64_decode() that could

Janos Follath5ad40452017-02-03 12:36:59 +0000149 * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
150 Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
Andres AGf4cbe102016-12-08 17:19:21 +0000151 * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
152 by missing calls to mbedtls_pem_free() in cases when a
Simon Butcher763e3272017-02-28 16:36:22 +0000153 MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
154 fix proposed by Guido Vranken. #722

Manuel Pégourié-Gonnard2f84e972015-05-11 09:52:24 +0200460 been split into an _init() that returns void and another function that
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200461 should generally be the first function called on this context after init:
Manuel Pégourié-Gonnard41d479e2015-04-29 00:48:22 +0200462 mbedtls_ssl_init() -> mbedtls_ssl_setup()
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +0200463 mbedtls_ccm_init() -> mbedtls_ccm_setkey()

466 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Tillmann Karras588ad502015-09-25 04:27:22 +0200467 Note that for mbedtls_ssl_setup(), you need to be done setting up the
Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200468 ssl_config structure before calling it.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100469 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),

478 mbedtls_ssl_set_hs_own_cert()
479 mbedtls_ssl_set_hs_ca_chain()
480 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200481 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100482 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200483 * mbedtls_ssl_conf_session_cache() changed prototype (only one context
Manuel Pégourié-Gonnard5cb33082015-05-06 18:06:26 +0100484 pointer, parameters reordered).

Manuel Pégourié-Gonnarde6ef16f2015-05-11 19:54:43 +0200495 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
Manuel Pégourié-Gonnardbc6ff232015-06-02 16:33:08 +0100496 * The following functions changed prototype to avoid an in-out length
497 parameter:
498 mbedtls_base64_encode()
499 mbedtls_base64_decode()
500 mbedtls_mpi_write_string()
501 mbedtls_dhm_calc_secret()

513 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
514 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100515 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200516 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
517 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
518 length parameter to include the terminating null byte for PEM input.

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +0200575 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
576 enabled in the default configuration, this is only noticeable if using a
577 custom config.h

602 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
603 an example implementation, see mbedtls_timing_delay_context and
