Hanno Becker4d48bb62017-11-20 10:31:05 +00006 * Fix heap corruption in implementation of truncated HMAC extension.
7 When the truncated HMAC extension is enabled and CBC is used,
8 sending a malicious application packet can be used to selectively
9 corrupt 6 bytes on the peer's heap, potentially leading to crash or
10 remote code execution. This can be triggered remotely from either
11 side.
Gilles Peskine55db24c2017-10-17 19:01:38 +020012 * Fix buffer overflow in RSA-PSS verification when the hash is too
13 large for the key size. Found by Seth Terashima, Qualcomm Product
14 Security Initiative, Qualcomm Technologies Inc.
Gilles Peskine511bb842017-10-17 19:02:13 +020015 * Fix buffer overflow in RSA-PSS verification when the unmasked
16 data is all zeros.
Gilles Peskinefeae81d2017-11-23 19:10:48 +010017 * Fix unsafe bounds check in ssl_parse_client_psk_identity() when adding
18 64kB to the address of the SSL buffer wraps around.
Gilles Peskine1caad082017-11-28 13:35:09 +010019 * Tighten should-be-constant-time memcmp against compiler optimizations.
Andres Amaya Garciaaf134da2017-07-12 10:59:05 +010020 * Ensure that buffers are cleared after use if they contain sensitive data.
21 Changes were introduced in multiple places in the library.
Ron Eldor27ce0b52017-09-05 15:34:35 +030022 * Set PEM buffer to zero before freeing it, to avoid decoded private keys
23 being leaked to memory after release.
Janos Follath77359c92017-09-20 15:33:24 +010024 * Fix dhm_check_range() failing to detect trivial subgroups and potentially
25 leaking 1 bit of the private key. Reported by prashantkspatil.
Hanno Becker825c3db2017-10-25 16:10:07 +010026 * Make mpi_read_binary constant-time with respect to
27 the input data. Previously, trailing zero bytes were detected
28 and omitted for the sake of saving memory, but potentially
29 leading to slight timing differences.
30 Reported by Marco Macchetti, Kudelski Group.
31 * Wipe stack buffer temporarily holding EC private exponent
32 after keypair generation.
Gilles Peskine55db24c2017-10-17 19:01:38 +020033
Gilles Peskine605c2282017-12-19 18:10:51 +010034Features
35 * Allow comments in test data files.

Hanno Beckerad951d12017-11-29 17:51:03 +000038 * Fix typo in ssl.h leading to a too small value of SSL_MAC_ADD
39 in case CBC is disabled but ARC4 is enabled.
Hanno Beckerce2c02c2017-05-05 13:10:08 +010040 * Fix memory leak in ssl_set_hostname() when called multiple times.
41 Found by projectgus and jethrogb, #836.
Simon Butcher7d661f82017-10-02 19:12:54 +010042 * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.

44 x509.c modules and some sample applications.
Ron Eldor4491a792017-10-03 15:58:26 +030045 * Parse signature algorithm extension when renegotiating. Previously,
46 renegotiated handshakes would only accept signatures using SHA-1
47 regardless of the peer's preferences, or fail if SHA-1 was disabled.
Andres AG7c02d132016-11-21 15:38:02 +000048 * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
49 dates on leap years with 100 and 400 intervals are handled correctly. Found
50 by Nicholas Wilson. #694
Gilles Peskine28474f42017-10-19 17:46:14 +020051 * Fix some invalid RSA-PSS signatures with keys of size 8N+1 that were
52 accepted. Generating these signatures required the private key.
Hanno Beckerea65d032017-09-28 16:50:22 +010053 * Fix out-of-memory problem when parsing 4096-bit PKCS8-encrypted RSA keys.
54 Found independently by Florian in the mbed TLS forum and by Mishamax.
55 #878, #1019.
Gilles Peskine80838492017-11-28 15:27:48 +010056 * Fix build problems on Windows. Contributed by Nicholas Wilson.
Andres Amaya Garciaf5e753a2017-05-30 17:18:06 +010057 * Fix unchecked return codes from AES, DES and 3DES functions in
58 pem_aes_decrypt(), pem_des_decrypt() and pem_des3_decrypt() respectively.
59 If a call to one of the functions of the cryptographic primitive modules
60 failed, the error may not be noticed by the function pem_read_buffer()
61 causing it to return invalid values. Found by Guido Vranken. #756
Gilles Peskine43a6b832017-11-28 18:40:10 +010062 * Include configuration file in md.h, to fix compilation warnings.
63 Reported by aaronmdjones in #1001
Hanno Becker234d5032017-09-28 14:45:35 +010064 * Correct extraction of signature-type from PK instance in X.509 CRT and CSR
65 writing routines that prevented these functions to work with alternative
66 RSA implementations. Raised by J.B. in the Mbed TLS forum. Fixes #1011.
Hanno Beckera6cffa52017-10-05 08:58:00 +010067 * Don't print X.509 version tag for v1 CRT's, and omit extensions for
68 non-v3 CRT's.
Gilles Peskine8c946112017-11-28 18:42:21 +010069 * Fix bugs in RSA test suite under MBEDTLS_NO_PLATFORM_ENTROPY. #1023 #1024

71 Found by nkolban. Fixes #845.
Hanno Becker18710eb2017-10-25 09:50:22 +010072 * Fix handling of handshake messages in ssl_read in case
73 POLARSSL_SSL_DISABLE_RENEGOTIATION is set. Found by erja-gp.
Darryl Greenfdac76f2017-11-20 15:53:43 +000074 * Add a check for invalid private parameters in ecdsa_sign.
75 Reported by Yolan Romailler.
Gilles Peskine4905e6c2017-12-04 17:29:13 +010076 * Fix word size check in in pk.c to not depend on MBEDTLS_HAVE_INT64.
Ron Eldor1f311ed2017-10-17 18:15:41 +030077 * Fix crash when calling mbedtls_ssl_cache_free() twice. Found by
78 MilenkoMitrovic, #1104
Gilles Peskinede896eb2017-10-10 20:10:46 +020079 * Fix mbedtls_timing_alarm(0) on Unix.

Hanno Beckera6cffa52017-10-05 08:58:00 +010081
82Changes
83 * Extend cert_write example program by options to set the CRT version
84 and the message digest. Further, allow enabling/disabling of authority
85 identifier, subject identifier and basic constraints extensions.
Gilles Peskine605c2282017-12-19 18:10:51 +010086 * Improve makefiles on Windows: don't run find, and call perl explicitly.
Gilles Peskinef1cc6a42017-09-29 15:45:12 +020087

Ron Eldorb34be242016-12-16 16:15:56 +020090Security
Simon Butcher9ee59102017-08-10 10:49:32 +010091 * Fix authentication bypass in SSL/TLS: when authmode is set to optional,
92 mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
93 X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
94 (default: 8) intermediates, even when it was not trusted. This could be
95 triggered remotely from either side. (With authmode set to 'required'
96 (the default), the handshake was correctly aborted).
97 * Reliably zeroize sensitive data after use in AES example applications
Hanno Becker56fa40f2017-06-27 08:47:52 +010098 programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
99 Found by Laurent Simon.
Ron Eldorb34be242016-12-16 16:15:56 +0200100
101API Changes
102 * Certificate verification functions now set flags to -1 in case the full
103 chain was not verified due to an internal error (including in the verify
104 callback) or chain length limitations.
Simon Butcher9ee59102017-08-10 10:49:32 +0100105 * With authmode set to optional, the TLS handshake is now aborted if the
Ron Eldorb34be242016-12-16 16:15:56 +0200106 verification of the peer's certificate failed due to an overlong chain or
Simon Butcher9ee59102017-08-10 10:49:32 +0100107 a fatal error in the verify callback.

Simon Butcher9ee59102017-08-10 10:49:32 +0100110 * Add a check if iv_len is zero in GCM, and return an error if it is zero.
111 Reported by roberto. #716
112 * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
Ron Eldor77718242017-01-09 19:27:59 +0200113 to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
114 always be implemented by pthread support. Fix for #696
Simon Butcher9ee59102017-08-10 10:49:32 +0100115 * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
116 in the case of an error. Found by redplait. #590
Ron Eldor57501ef2017-01-12 14:50:50 +0200117 * Add MPI_CHK to check for error value of mpi_fill_random.
118 Backported from a report and fix suggestion by guidovranken in #740
Andres AG26124be2017-03-01 15:14:30 +0000119 * Fix a potential integer overflow in the version verification for DER
120 encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
121 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
122 KNOX Security, Samsung Research America
Andres AG47f30592017-03-09 16:46:14 +0000123 * Fix a potential integer overflow in the version verification for DER
124 encoded X509 certificates. The overflow would enable maliciously
125 constructed certificates to bypass the certificate verification check.
Andres AG3df4e4e2017-03-01 14:59:02 +0000126 * Fix potential integer overflow in the version verification for DER

Hanno Beckerb9c09af2017-06-09 11:31:43 +0100139 * Fixed unlimited overread of heap-based buffer in ssl_read().
140 The issue could only happen client-side with renegotiation enabled.
141 Could result in DoS (application crash) or information leak
142 (if the application layer sent data read from ssl_read()
143 back to the server or to a third party). Can be triggered remotely.
Janos Follath3682db52017-03-23 10:41:56 +0000144 * Add exponent blinding to RSA private operations as a countermeasure
145 against side-channel attacks like the cache attack described in

Hanno Beckercc608e82017-06-09 15:39:30 +0100158 * Disable use of extensions for SSLv3, previously causing the
159 "SSLv3 with extensions" test from ssl-opt.sh to fail.
Hanno Beckerc2b9d982017-05-10 16:37:21 +0100160 * Fix insufficient support for signature-hash-algorithm extension,
161 resulting in compatibility problems with Chrome. Found by hfloyrd. #823
Hanno Becker888c2fd2017-05-11 11:12:40 +0100162 * Accept empty trusted CA chain in authentication mode
Janos Follath3aab1a82017-06-16 14:28:37 +0100163 SSL_VERIFY_OPTIONAL. Found by jethrogb. #864.
164 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
165 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
166 reflect bad EC curves within verification result.
167 * Fix bug that caused the modular inversion function to accept the invalid
168 modulus 1 and therefore to hang. Found by blaufish. #641.
169 * Fix incorrect sign computation in modular exponentiation when the base is
170 a negative MPI. Previously the result was always negative. Found by Guido
171 Vranken.
172 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
173 that was triggered uppon reading an empty line. Found by Guido Vranken.

Janos Follath5d96a3d2017-03-10 11:31:41 +0000175Changes
176 * Clarify ECDSA documentation and improve the sample code to avoid
Janos Follath3aab1a82017-06-16 14:28:37 +0100177 misunderstanding and potentially dangerous use of the API. Pointed out
Janos Follath5d96a3d2017-03-10 11:31:41 +0000178 by Jean-Philippe Aumasson.
Manuel Pégourié-Gonnard6d61e972017-06-09 14:52:09 +0200179 * Add new config.h flag POLARSSL_X509_MIN_VERIFY_MD_ALG to set the minimum
180 hash accepted when verifying certificate chains. Defaults to SHA1, which
181 means SHA1 is accepted but MD5 and below are rejected.

Simon Butcher7346a7e2017-02-26 02:01:49 +0000186 * Add checks to prevent signature forgeries for very large messages while
187 using RSA through the PK module in 64-bit systems. The issue was caused by
188 some data loss when casting a size_t to an unsigned int value in the
189 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
190 pk_sign(). Found by Jean-Philippe Aumasson.
Andres AGe5671012016-12-08 17:08:44 +0000191 * Fixed potential livelock during the parsing of a CRL in PEM format in
192 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
193 characters after the footer could result in the execution of an infinite
194 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
195 Microsoft.
Janos Follathf5ffc792017-01-27 16:05:20 +0000196 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
197 when verifying the validity of a key on secp224k1. This could be
198 triggered remotely for example with a maliciously constructed certificate
Simon Butcher866a4472017-02-28 18:47:27 +0000199 and potentially could lead to remote code execution on some platforms.
