5Bugfix
6 * Fix memory leak in ssl_set_hostname() when called multiple times.
7 Found by projectgus and jethrogb, #836.
Simon Butcher7d661f82017-10-02 19:12:54 +01008 * Fix usage help in ssl_server2 example. Found and fixed by Bei Lin.
Andres Amaya Garcia10345fb2017-07-31 16:45:44 +01009 * Fix Visual Studio implicit cast compilation warnings in the net.c and
10 x509.c modules and some sample applications.
Ron Eldor4491a792017-10-03 15:58:26 +030011 * Parse signature algorithm extension when renegotiating. Previously,
12 renegotiated handshakes would only accept signatures using SHA-1
13 regardless of the peer's preferences, or fail if SHA-1 was disabled.
Andres AG7c02d132016-11-21 15:38:02 +000014 * Fix leap year calculation in x509_date_is_valid() to ensure that invalid
15 dates on leap years with 100 and 400 intervals are handled correctly. Found
16 by Nicholas Wilson. #694
Hanno Beckerea65d032017-09-28 16:50:22 +010017 * Fix out-of-memory problem when parsing 4096-bit PKCS8-encrypted RSA keys.

Simon Butcher9ee59102017-08-10 10:49:32 +010024 * Fix authentication bypass in SSL/TLS: when authmode is set to optional,
25 mbedtls_ssl_get_verify_result() would incorrectly return 0 when the peer's
26 X.509 certificate chain had more than MBEDTLS_X509_MAX_INTERMEDIATE_CA
27 (default: 8) intermediates, even when it was not trusted. This could be
28 triggered remotely from either side. (With authmode set to 'required'
29 (the default), the handshake was correctly aborted).
30 * Reliably zeroize sensitive data after use in AES example applications
Hanno Becker56fa40f2017-06-27 08:47:52 +010031 programs/aes/aescrypt2 and programs/aes/crypt_and_hash.
32 Found by Laurent Simon.
Ron Eldorb34be242016-12-16 16:15:56 +020033
34API Changes
35 * Certificate verification functions now set flags to -1 in case the full
36 chain was not verified due to an internal error (including in the verify
37 callback) or chain length limitations.
Simon Butcher9ee59102017-08-10 10:49:32 +010038 * With authmode set to optional, the TLS handshake is now aborted if the
Ron Eldorb34be242016-12-16 16:15:56 +020039 verification of the peer's certificate failed due to an overlong chain or
Simon Butcher9ee59102017-08-10 10:49:32 +010040 a fatal error in the verify callback.
Ron Eldorb34be242016-12-16 16:15:56 +020041
Ron Eldor4f1e64e2016-12-16 16:15:56 +020042Bugfix
Simon Butcher9ee59102017-08-10 10:49:32 +010043 * Add a check if iv_len is zero in GCM, and return an error if it is zero.
44 Reported by roberto. #716
45 * Replace preprocessor condition from #if defined(MBEDTLS_THREADING_PTHREAD)
Ron Eldor77718242017-01-09 19:27:59 +020046 to #if defined(MBEDTLS_THREADING_C) as the library cannot assume they will
47 always be implemented by pthread support. Fix for #696
Simon Butcher9ee59102017-08-10 10:49:32 +010048 * Fix a resource leak on Windows platforms in mbedtls_x509_crt_parse_path(),
49 in the case of an error. Found by redplait. #590
Ron Eldor57501ef2017-01-12 14:50:50 +020050 * Add MPI_CHK to check for error value of mpi_fill_random.
51 Backported from a report and fix suggestion by guidovranken in #740
Andres AG26124be2017-03-01 15:14:30 +000052 * Fix a potential integer overflow in the version verification for DER
53 encoded X509 CRLs. The overflow would enable maliciously constructed CRLs
54 to bypass the version verification check. Found by Peng Li/Yueh-Hsun Lin,
55 KNOX Security, Samsung Research America
Andres AG47f30592017-03-09 16:46:14 +000056 * Fix a potential integer overflow in the version verification for DER

71Security
Hanno Beckerb9c09af2017-06-09 11:31:43 +010072 * Fixed unlimited overread of heap-based buffer in ssl_read().
73 The issue could only happen client-side with renegotiation enabled.
74 Could result in DoS (application crash) or information leak
75 (if the application layer sent data read from ssl_read()
76 back to the server or to a third party). Can be triggered remotely.
Janos Follath3682db52017-03-23 10:41:56 +000077 * Add exponent blinding to RSA private operations as a countermeasure
78 against side-channel attacks like the cache attack described in
79 https://arxiv.org/abs/1702.08719v2.
80 Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,
81 Clémentine Maurice and Stefan Mangard.

Janos Follath3aab1a82017-06-16 14:28:37 +010083 (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt). Found by Laurent
84 Simon.
Manuel Pégourié-Gonnard6d61e972017-06-09 14:52:09 +020085 * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
Manuel Pégourié-Gonnard19c10e92017-05-11 12:49:51 +020086 potential Bleichenbacher/BERserk-style attack.
Ron Eldora9ec0cd2017-02-09 19:29:33 +020087 * Remove support for X509 certificates signed with MD5.
88 Issue raised by Harm Verhagen

Hanno Beckerc2b9d982017-05-10 16:37:21 +010090Bugfix
Hanno Beckercc608e82017-06-09 15:39:30 +010091 * Disable use of extensions for SSLv3, previously causing the
92 "SSLv3 with extensions" test from ssl-opt.sh to fail.
Hanno Beckerc2b9d982017-05-10 16:37:21 +010093 * Fix insufficient support for signature-hash-algorithm extension,
94 resulting in compatibility problems with Chrome. Found by hfloyrd. #823
Hanno Becker888c2fd2017-05-11 11:12:40 +010095 * Accept empty trusted CA chain in authentication mode
Janos Follath3aab1a82017-06-16 14:28:37 +010096 SSL_VERIFY_OPTIONAL. Found by jethrogb. #864.
97 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
98 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
99 reflect bad EC curves within verification result.
100 * Fix bug that caused the modular inversion function to accept the invalid
101 modulus 1 and therefore to hang. Found by blaufish. #641.
102 * Fix incorrect sign computation in modular exponentiation when the base is
103 a negative MPI. Previously the result was always negative. Found by Guido
104 Vranken.
105 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
106 that was triggered uppon reading an empty line. Found by Guido Vranken.

Janos Follath5d96a3d2017-03-10 11:31:41 +0000108Changes
109 * Clarify ECDSA documentation and improve the sample code to avoid
Janos Follath3aab1a82017-06-16 14:28:37 +0100110 misunderstanding and potentially dangerous use of the API. Pointed out
Janos Follath5d96a3d2017-03-10 11:31:41 +0000111 by Jean-Philippe Aumasson.
Manuel Pégourié-Gonnard6d61e972017-06-09 14:52:09 +0200112 * Add new config.h flag POLARSSL_X509_MIN_VERIFY_MD_ALG to set the minimum
113 hash accepted when verifying certificate chains. Defaults to SHA1, which
114 means SHA1 is accepted but MD5 and below are rejected.

118Security
Simon Butcher7346a7e2017-02-26 02:01:49 +0000119 * Add checks to prevent signature forgeries for very large messages while
120 using RSA through the PK module in 64-bit systems. The issue was caused by
121 some data loss when casting a size_t to an unsigned int value in the
122 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
123 pk_sign(). Found by Jean-Philippe Aumasson.
Andres AGe5671012016-12-08 17:08:44 +0000124 * Fixed potential livelock during the parsing of a CRL in PEM format in
125 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
126 characters after the footer could result in the execution of an infinite
127 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
128 Microsoft.
Janos Follathf5ffc792017-01-27 16:05:20 +0000129 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
130 when verifying the validity of a key on secp224k1. This could be
131 triggered remotely for example with a maliciously constructed certificate
Simon Butcher866a4472017-02-28 18:47:27 +0000132 and potentially could lead to remote code execution on some platforms.
Simon Butcher2e5318e2017-03-07 12:46:05 +0000133 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos

136Bugfix
Andres AG2f3fe702017-01-20 17:07:46 +0000137 * Fix output certificate verification flags set by x509_crt_verify_top() when
138 traversing a chain of trusted CA. The issue would cause both flags,
139 BADCERT_NOT_TRUSTED and BADCERT_EXPIRED, to be set when the verification
140 conditions are not met regardless of the cause. Found by Harm Verhagen and
141 inestlerode. #665 #561
Andres AGd3cbc152016-10-24 11:23:36 +0100142 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

Simon Butcherbb4bebc2017-03-10 20:31:09 +0000148 * Fixed potential arithmetic overflow in ctr_drbg_reseed() that could cause
149 buffer bound checks to be bypassed. Found by Eyal Itkin.
150 * Fixed potential arithmetic overflows in cipher_update() that could cause
151 buffer bound checks to be bypassed. Found by Eyal Itkin.
152 * Fixed potential arithmetic overflow in md2_update() that could cause buffer
153 bound checks to be bypassed. Found by Eyal Itkin.
154 * Fixed potential arithmetic overflow in base64_decode() that could cause
155 buffer bound checks to be bypassed. Found by Eyal Itkin.
Andres AG03af0e02017-01-23 14:58:27 +0000156 * Fix potential memory leak in x509_crl_parse(). The leak was caused by
157 missing calls to pem_free() in cases when a
Simon Butcherbfef0ce2017-02-28 16:36:22 +0000158 POLARSSL_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
159 fix proposed by Guido Vranken. #722
Simon Butcherdccf7432017-03-02 09:18:09 +0000160 * Fixed the templates used to generate project and solution files for Visual
161 Studio 2015 as well as the files themselves, to remove a build warning
162 generated in Visual Studio 2015. Reported by Steve Valliere. #742
Andres AG2b2fc112017-03-01 14:04:08 +0000163 * Fix 1 byte buffer overflow in mpi_write_string() when the MPI number to
164 write in hexadecimal is negative and requires an odd number of digits.
165 Found and fixed by Guido Vranken.
Simon Butchera42044d2017-03-07 19:35:49 +0000166 * Fix unlisted DES configuration dependency in some pkparse test cases. Found

Paul Bakkera35aa542013-03-06 17:06:21 +01001560 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1561 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1562 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1563 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001564 * Network functions now return POLARSSL_ERR_NET_WANT_READ or

Paul Bakker98675492011-03-26 13:17:12 +00001581 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001582 before parsing a key or keyfile!
Paul Bakkerbe4e7dc2011-03-14 20:41:31 +00001583
