5Bugfix
Simon Butcher945dfe62018-10-25 16:18:13 +01006 * Fix failure in hmac_drbg in the benchmark sample application, when
7 MBEDTLS_THREADING_C is defined. Found by TrinityTonic, #1095
8 * Fix a bug in the update function for SSL ticket keys which previously
9 invalidated keys of a lifetime of less than a 1s. Fixes #1968.
10 * Fix potential build failures related to the 'apidoc' target, introduced
11 in the previous patch release. Found by Robert Scheck. #390 #391
Simon Butcher351c4f12018-10-28 16:32:05 +000012 * Fix a bug in the record decryption routine ssl_decrypt_buf()
13 which lead to accepting properly authenticated but improperly
14 padded records in case of CBC ciphersuites using Encrypt-then-MAC.
Simon Butcherc84f5c92018-10-28 16:58:29 +000015 * Fix wrong order of freeing in programs/ssl/ssl_server2 example
16 application leading to a memory leak in case both
17 MBEDTLS_MEMORY_BUFFER_ALLOC_C and MBEDTLS_MEMORY_BACKTRACE are set.
18 Fixes #2069.
Hanno Beckerdb057932018-10-05 09:51:36 +010019 * Fix memory leak and freeing without initialization in the example
20 program programs/x509/cert_write. Fixes #1422.
Ron Eldor0bd06a32017-09-25 17:03:12 +030021 * Ignore iv in mbedtls_cipher_set_iv() when the cipher mode is MBEDTLS_MODE_ECB
22 Fix for #1091 raised by ezdevelop

24Changes
Simon Butcher945dfe62018-10-25 16:18:13 +010025 * "make apidoc" now generates the documentation for the current
26 configuration. Run "scripts/apidoc_full.sh" to generate the full
27 documentation. This aligns the behavior with Mbed TLS versions 2.2 and
28 later and reverts it back to how it behaved in version 2.1.3.
Simon Butcher86d32e62018-09-26 22:39:29 +010029 * Add tests for session resumption in DTLS.
Simon Butcher5bcbd4e2018-09-26 23:03:56 +010030 * Close a test gap in (D)TLS between the client side and the server side:
31 test the handling of large packets and small packets on the client side
32 in the same way as on the server side.
Simon Butcher948dcee2018-05-12 20:28:56 +010033 * Change the dtls_client and dtls_server samples to work by default over
34 IPv6 and optionally by a build option over IPv4.

k-stachowiakb435e992018-07-16 12:14:18 +020039 * Fix an issue in the X.509 module which could lead to a buffer overread
40 during certificate extensions parsing. In case of receiving malformed
41 input (extensions length field equal to 0), an illegal read of one byte
42 beyond the input buffer is made. Found and analyzed by Nathan Crandall.

Simon Butchercb9f70e2018-08-31 12:01:43 +010045 * Fix a potential memory leak in mbedtls_ssl_setup() function. An allocation
46 failure in the function could lead to other buffers being leaked.
Simon Butcher96e0d8e2018-09-13 12:05:40 +010047 * Fixes a missing test dependency on MBEDTLS_ARC4_C. #1890
Jaeden Ameroe3bcd9a2018-08-10 10:50:03 +010048 * Fix a memory leak in ecp_mul_comb() if ecp_precompute_comb() fails.
49 Fix contributed by Espressif Systems.
Ron Eldor5c141d22018-06-21 16:40:24 +030050 * Add ecc extensions only if an ecc based ciphersuite is used.
Ron Eldorf27f8ae2018-06-28 11:09:09 +030051 This improves compliance to RFC 4492, and as a result, solves
52 interoperability issues with BouncyCastle. Raised by milenamil in #1157.
Hanno Becker048dba32018-08-13 16:36:58 +010053 * Fix potential use-after-free in mbedtls_ssl_get_max_frag_len()
54 and mbedtls_ssl_get_record_expansion() after a session reset. Fixes #1941.
Hanno Beckerd3475492018-08-03 09:53:48 +010055 * Fix a miscalculation of the maximum record expansion in
56 mbedtls_ssl_get_record_expansion() in case of CBC ciphersuites
57 in (D)TLS versions 1.1 or higher. Fixes #1914.
Hanno Becker10652b12018-08-17 09:47:22 +010058 * Fix a bug that caused SSL/TLS clients to incorrectly abort the handshake
59 with TLS versions 1.1 and earlier when the server requested authentication
60 without providing a list of CAs. This was due to an overly strict bounds
Simon Butcher96e0d8e2018-09-13 12:05:40 +010061 check in parsing the CertificateRequest message, introduced in
62 Mbed TLS 2.12.0. Fixes #1954.
Philippe Antoine795eea62018-05-11 11:06:29 +020063 * Fix undefined shifts with negative values in certificates parsing
64 (found by Catena cyber using oss-fuzz)
Hanno Becker47a34ff2017-10-08 16:13:03 +010065 * Fix memory leak and free without initialization in pk_encrypt
66 and pk_decrypt example programs. Reported by Brace Stout. Fixes #1128.

71 * Fix a vulnerability in TLS ciphersuites based on CBC and using SHA-384,
72 in (D)TLS 1.0 to 1.2, that allowed an active network attacker to
73 partially recover the plaintext of messages under some conditions by
74 exploiting timing measurements. With DTLS, the attacker could perform
75 this recovery by sending many messages in the same connection. With TLS
76 or if mbedtls_ssl_conf_dtls_badmac_limit() was used, the attack only
77 worked if the same secret (for example a HTTP Cookie) has been repeatedly
78 sent over connections manipulated by the attacker. Connections using GCM
79 or CCM instead of CBC, using hash sizes other than SHA-384, or using
80 Encrypt-then-Mac (RFC 7366) were not affected. The vulnerability was
81 caused by a miscalculation (for SHA-384) in a countermeasure to the
82 original Lucky 13 attack. Found by Kenny Paterson, Eyal Ronen and Adi
83 Shamir.
Manuel Pégourié-Gonnard69675d02018-06-28 12:10:27 +020084 * Fix a vulnerability in TLS ciphersuites based on CBC, in (D)TLS 1.0 to
85 1.2, that allowed a local attacker, able to execute code on the local
86 machine as well as manipulate network packets, to partially recover the
Manuel Pégourié-Gonnard534fea72018-07-11 18:27:08 +020087 plaintext of messages under some conditions by using a cache attack
88 targetting an internal MD/SHA buffer. With TLS or if
89 mbedtls_ssl_conf_dtls_badmac_limit() was used, the attack only worked if
90 the same secret (for example a HTTP Cookie) has been repeatedly sent over
91 connections manipulated by the attacker. Connections using GCM or CCM
92 instead of CBC or using Encrypt-then-Mac (RFC 7366) were not affected.
93 Found by Kenny Paterson, Eyal Ronen and Adi Shamir.
Manuel Pégourié-Gonnard99b6a712018-06-28 10:38:35 +020094 * Add a counter-measure against a vulnerability in TLS ciphersuites based
95 on CBC, in (D)TLS 1.0 to 1.2, that allowed a local attacker, able to
96 execute code on the local machine as well as manipulate network packets,
97 to partially recover the plaintext of messages under some conditions (see
98 previous entry) by using a cache attack targeting the SSL input record
99 buffer. Connections using GCM or CCM instead of CBC or using
100 Encrypt-then-Mac (RFC 7366) were not affected. Found by Kenny Paterson,
101 Eyal Ronen and Adi Shamir.

105 Found and fixed by Hirotaka Niisato in #1783.
Simon Butcher54cf3222018-06-24 16:20:56 +0100106 * Fix the inline assembly for the MPI multiply helper function for i386 and
107 i386 with SSE2. Found by László Langó. Fixes #1550
Simon Butcher584fad22018-06-22 12:02:59 +0100108 * Fix a memory leak in mbedtls_x509_csr_parse(), found by catenacyber,
Simon Butcherb461ba52018-06-28 12:14:07 +0100109 Philippe Antoine. Fixes #1623.
Andres Amaya Garcia45bc7db2017-07-11 14:39:30 +0100110 * Clarify documentation for mbedtls_ssl_write() to include 0 as a valid
111 return value. Found by @davidwu2000. #839
Simon Butcher03c79a12018-06-28 12:00:55 +0100112 * Fix the key_app_writer example which was writing a leading zero byte which
113 was creating an invalid ASN.1 tag. Found by Aryeh R. Fixes #1257
Simon Butcher4b57a1f2018-07-02 12:00:54 +0100114 * Remove unused headers included in x509.c. Found by Chris Hanson and fixed
115 by Brendan Shanks. Part of a fix for #992.
Ron Eldord7593a52018-06-17 14:51:59 +0300116 * Fix compilation error when MBEDTLS_ARC4_C is disabled and
117 MBEDTLS_CIPHER_NULL_CIPHER is enabled. Found by TrinityTonic in #1719.
Simon Butcherff5bd622018-07-19 19:59:02 +0100118 * Added length checks to some TLS parsing functions. Found and fixed by
119 Philippe Antoine from Catena cyber. #1663.
Ron Eldore6c2f4d2017-10-01 17:11:54 +0300120 * Fix namespacing in header files. Remove the `mbedtls` namespacing in
Ron Eldor2c8a7ec2017-05-14 16:17:33 +0300121 the `#include` in the header files. Resolves #857
Simon Butcherbe9c2dc2018-07-24 13:01:59 +0100122 * Fix decryption for zero length messages (which contain all padding) when a
123 CBC based ciphersuite is used together with Encrypt-then-MAC. Previously,
124 such a message was wrongly reported as an invalid record and therefore lead
125 to the connection being terminated. Seen most often with OpenSSL using
126 TLS 1.0. Reported by @kFYatek and by Conor Murphy on the forum. Fix
127 contributed by Espressif Systems. Fixes #1632
Andres Amaya Garcia01daf2a2018-07-04 10:01:39 +0100128 * Fix ssl_client2 example to send application data with 0-length content
129 when the request_size argument is set to 0 as stated in the documentation.
130 Fixes #1833.
Simon Butcherd9084942018-07-25 17:33:29 +0100131 * Correct the documentation for `mbedtls_ssl_get_session()`. This API has
132 deep copy of the session, and the peer certificate is not lost. Fixes #926.

Simon Butcherd9084942018-07-25 17:33:29 +0100135 * Fail when receiving a TLS alert message with an invalid length, or invalid
136 zero-length messages when using TLS 1.2. Contributed by Espressif Systems.
Simon Butcherba3e5e62018-06-22 15:07:00 +0100137 * Change the shebang line in Perl scripts to look up perl in the PATH.

Simon Butcher577d39b2018-06-14 08:58:59 +0100143 * Fix compilation warnings with IAR toolchain, on 32 bit platform.
144 Reported by rahmanih in #683
Simon Butcher7350ab12018-05-23 17:55:02 +0100145 * Fix braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden, #552.
Simon Butcher13188782018-05-11 16:41:07 +0100146 * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
147 configure the maximum length of a file path that can be buffered when
148 calling mbedtls_x509_crt_parse_path().
Moran Peker6981df52018-02-25 13:29:03 +0200149 * Fix redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by
150 TrinityTonic. #1359.
Simon Butcherdb3fe7c2018-06-01 19:11:55 +0100151 * Fix an issue with MicroBlaze support in bn_mul.h which was causing the
152 build to fail. Found by zv-io. Fixes #1651.
Simon Butcher0c362f62018-06-08 16:27:04 +0100153 * Fix for redefinition of _WIN32_WINNT to avoid overriding a definition
154 used by user applications. Found and fixed by Fabio Alessandrelli.

Gilles Peskineeea857d2018-03-21 12:35:44 +0100156Changes
157 * Support TLS testing in out-of-source builds using cmake.
Simon Butcher494fb8f2018-06-18 11:56:46 +0100158 * Changed the Clang parameters used in the CMake build files to work for
159 versions later than 3.6. Fixes #1072

163Security
Simon Butcher50d80212018-04-30 17:23:10 +0100164 * Fix an issue in the X.509 module which could lead to a buffer overread
165 during certificate validation. Additionally, the issue could also lead to
166 unnecessary callback checks being made or to some validation checks to be
167 omitted. The overread could be triggered remotely, while the other issues
168 would require a non DER-compliant certificate to be correctly signed by a
169 trusted CA, or a trusted CA with a non DER-compliant certificate. Found by
170 luocm. Fixes #825.
171 * Fix the buffer length assertion in the ssl_parse_certificate_request()
172 function which led to an arbitrary overread of the message buffer. The
173 overreads could be caused by receiving a malformed message at the point
174 where an optional signature algorithms list is expected when the signature
175 algorithms section is too short. In builds with debug output, the overread
176 data is output with the debug data.
Andrzej Kurek128bcbe2018-04-25 05:25:30 -0400177 * Fix a client-side bug in the validation of the server's ciphersuite choice
Simon Butcher50d80212018-04-30 17:23:10 +0100178 which could potentially lead to the client accepting a ciphersuite it didn't
179 offer or a ciphersuite that cannot be used with the TLS or DTLS version
180 chosen by the server. This could lead to corruption of internal data
181 structures for some configurations.

Gilles Peskined888bd22018-03-23 01:42:44 +0100183Bugfix
184 * Add missing dependencies in test suites that led to build failures
185 in configurations that omit certain hashes or public-key algorithms.
186 Fixes #1040.
Gilles Peskinef362b972018-03-27 23:08:53 +0200187 * Add missing dependencies for MBEDTLS_HAVE_TIME_DATE and
Simon Butcher50d80212018-04-30 17:23:10 +0100188 MBEDTLS_VERSION_FEATURES in some test suites. Contributed by
189 Deomid Ryabkov. Fixes #1299, #1475.
190 * Fix the Makefile build process for building shared libraries on Mac OS X.
191 Fixed by mnacamura.
Jethro Beekman1a886ff2018-02-16 13:11:04 -0800192 * Fix parsing of PKCS#8 encoded Elliptic Curve keys. Previously Mbed TLS was
Simon Butcher50d80212018-04-30 17:23:10 +0100193 unable to parse keys which had only the optional parameters field of the
194 ECPrivateKey structure. Found by Jethro Beekman, fixed in #1379.
195 * Return the plaintext data more quickly on unpadded CBC decryption, as
196 stated in the mbedtls_cipher_update() documentation. Contributed by
197 Andy Leiserson.
AndrzejKurek0de43062018-04-03 19:38:45 +0200198 * Fix overriding and ignoring return values when parsing and writing to
199 a file in pk_sign program. Found by kevlut in #1142.
Krzysztof Stachowiak8fc134f2018-04-05 08:51:35 +0200200 * Fix buffer length assertions in the ssl_parse_certificate_request()
201 function which leads to a potential one byte overread of the message
202 buffer.
Andrzej Kurekbb666142018-04-23 08:29:36 -0400203 * Fix invalid buffer sizes passed to zlib during record compression and
204 decompression.

209 * Improve negative testing of X.509 parsing.
Andres Amaya Garcia2a0aee32018-03-21 15:35:01 +0000210 * Do not define global mutexes around readdir() and gmtime() in
211 configurations where the feature is disabled. Found and fixed by Gergely
212 Budai.
Andres Amaya Garcia47569d72018-03-27 21:19:50 +0100213 * Provide an empty implementation of mbedtls_pkcs5_pbes2() when
214 MBEDTLS_ASN1_PARSE_C is not enabled. This allows the use of PBKDF2
215 without PBES2. Fixed by Marcos Del Sol Vives.
Simon Butcher50d80212018-04-30 17:23:10 +0100216 * Improve the documentation of mbedtls_net_accept(). Contributed by Ivan
217 Krylov.
Darryl Green093c1702018-03-29 16:05:44 +0100218 * Improve the documentation of mbedtls_ssl_write(). Suggested by
219 Paul Sokolovsky in #1356.
Simon Butcher50d80212018-04-30 17:23:10 +0100220 * Add an option in the Makefile to support ar utilities where the operation
Andres Amaya Garciabc006672018-03-27 19:14:24 +0100221 letter must not be prefixed by '-', such as LLVM. Found and fixed by
222 Alex Hixon.
Andres Amaya Garcia83bffd32018-03-26 00:15:21 +0100223 * Allow configuring the shared library extension by setting the DLEXT
Andres Amaya Garciabc006672018-03-27 19:14:24 +0100224 environment variable when using the project makefiles.
Gilles Peskine24f45842018-04-04 10:18:37 +0200225 * In the SSL module, when f_send, f_recv or f_recv_timeout report
226 transmitting more than the required length, return an error. Raised by
Jaeden Ameroee6c8222018-04-03 12:07:19 +0100227 Sam O'Connor in #1245.
Jaeden Ameroac9939c2018-04-03 18:27:18 +0100228 * Improve robustness of mbedtls_ssl_derive_keys against the use of
229 HMAC functions with non-HMAC ciphersuites. Independently contributed
230 by Jiayuan Chen in #1377. Fixes #1437.

Manuel Pégourié-Gonnardf1985572018-03-06 10:34:56 +0100234Default behavior changes
235 * The truncated HMAC extension now conforms to RFC 6066. This means
236 that when both sides of a TLS connection negotiate the truncated
237 HMAC extension, Mbed TLS can now interoperate with other
238 compliant implementations, but this breaks interoperability with
239 prior versions of Mbed TLS. To restore the old behavior, enable
240 the (deprecated) option MBEDTLS_SSL_TRUNCATED_HMAC_COMPAT in
241 config.h. Found by Andreas Walz (ivESK, Offenburg University of
242 Applied Sciences).

Gilles Peskinee9256c52018-02-22 16:17:52 +0100245 * Fix implementation of the truncated HMAC extension. The previous
246 implementation allowed an offline 2^80 brute force attack on the
247 HMAC key of a single, uninterrupted connection (with no
248 resumption of the session).
Hanno Beckerd43764f2017-11-06 15:10:38 +0000249 * Verify results of RSA private key operations to defend
250 against Bellcore glitch attack.
Jaeden Amero4e362952018-03-14 17:38:21 +0000251 * Fix a buffer overread in ssl_parse_server_key_exchange() that could cause
252 a crash on invalid input.

Simon Butcherbdf548e2018-02-05 01:11:05 +0000308 * Fix a heap corruption issue in the implementation of the truncated HMAC
309 extension. When the truncated HMAC extension is enabled and CBC is used,
310 sending a malicious application packet could be used to selectively corrupt
311 6 bytes on the peer's heap, which could potentially lead to crash or remote
312 code execution. The issue could be triggered remotely from either side in
313 both TLS and DTLS. CVE-2018-0488
314 * Fix a buffer overflow in RSA-PSS verification when the hash was too large
315 for the key size, which could potentially lead to crash or remote code
316 execution. Found by Seth Terashima, Qualcomm Product Security Initiative,
317 Qualcomm Technologies Inc. CVE-2018-0487
318 * Fix buffer overflow in RSA-PSS verification when the unmasked data is all
319 zeros.
320 * Fix an unsafe bounds check in ssl_parse_client_psk_identity() when adding
321 64 KiB to the address of the SSL buffer and causing a wrap around.
322 * Fix a potential heap buffer overflow in mbedtls_ssl_write(). When the (by
Hanno Beckerb658ee62017-09-18 16:07:19 +0100323 default enabled) maximum fragment length extension is disabled in the
324 config and the application data buffer passed to mbedtls_ssl_write
325 is larger than the internal message buffer (16384 bytes by default), the
326 latter overflows. The exploitability of this issue depends on whether the
327 application layer can be forced into sending such large packets. The issue
328 was independently reported by Tim Nordell via e-mail and by Florin Petriuc
Simon Butcherbdf548e2018-02-05 01:11:05 +0000329 and sjorsdewit on GitHub. Fix proposed by Florin Petriuc in #1022.

342 differences. Reported by Marco Macchetti, Kudelski Group.

915 mbedtls_base64_decode()
916 mbedtls_mpi_write_string()

2137 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakkera35aa542013-03-06 17:06:21 +01002138 encountering a parse-error. Beware that the meaning of return values has
2139 changed!
Paul Bakker69e095c2011-12-10 21:55:01 +00002140 * All error codes are now negative. Even on mermory failures and IO errors.

2197 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
2198 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
2199 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00002200 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
