Manuel Pégourié-Gonnard489939f2017-06-22 12:19:27 +020028Changes
29 * Certificate verification functions now set flags to -1 in case the full
30 chain was not verified due to an internal error (including in the verify
31 callback) or chain length limitations.
Manuel Pégourié-Gonnardc3863172017-06-26 10:11:49 +020032 * With authmode set to optional, handshake is now aborted if the
33 verification of the peer's certificate failed due to an overlong chain or
34 a fatal error in the vrfy callback.

Hanno Becker88647ac2017-06-09 11:30:33 +010039 * Fixed unlimited overread of heap-based buffer in mbedtls_ssl_read().
40 The issue could only happen client-side with renegotiation enabled.
41 Could result in DoS (application crash) or information leak
42 (if the application layer sent data read from mbedtls_ssl_read()
43 back to the server or to a third party). Can be triggered remotely.
Janos Follath4477bca2017-03-23 10:41:56 +000044 * Add exponent blinding to RSA private operations as a countermeasure
45 against side-channel attacks like the cache attack described in
46 https://arxiv.org/abs/1702.08719v2.
47 Found and fix proposed by Michael Schwarz, Samuel Weiser, Daniel Gruss,
48 Clémentine Maurice and Stefan Mangard.
Gilles Peskine8877ec22017-03-23 14:37:37 +010049 * Wipe stack buffers in RSA private key operations
Janos Follath3fb1cc32017-06-16 14:04:08 +010050 (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt). Found by Laurent
51 Simon.
Gilles Peskine7344e1b2017-05-12 13:16:40 +020052 * Removed SHA-1 and RIPEMD-160 from the default hash algorithms for
53 certificate verification. SHA-1 can be turned back on with a compile-time
54 option if needed.
Gilles Peskine39e29812017-05-16 17:53:03 +020055 * Fixed offset in FALLBACK_SCSV parsing that caused TLS server to fail to
56 detect it sometimes. Reported by Hugo Leisink. #810
Manuel Pégourié-Gonnard230ee312017-05-11 12:49:51 +020057 * Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a
58 potential Bleichenbacher/BERserk-style attack.

Simon Butcher93d0f4b2017-05-13 23:00:05 +010060Bugfix
Andres Amaya Garciab9dee352017-05-02 16:01:20 +010061 * Remove macros from compat-1.3.h that correspond to deleted items from most
62 recent versions of the library. Found by Kyle Keen.
Janos Follath3fb1cc32017-06-16 14:04:08 +010063 * Fixed issue in the Threading module that prevented mutexes from
64 initialising. Found by sznaider. #667 #843
Hanno Beckeraa8a2bd2017-04-28 17:15:26 +010065 * Fix insufficient support for signature-hash-algorithm extension,
66 resulting in compatibility problems with Chrome. Found by hfloyrd. #823
Hanno Beckera3929ba2017-05-08 16:31:14 +010067 * Accept empty trusted CA chain in authentication mode
Janos Follath3fb1cc32017-06-16 14:04:08 +010068 MBEDTLS_SSL_VERIFY_OPTIONAL. Found by jethrogb. #864
69 * Fix implementation of mbedtls_ssl_parse_certificate() to not annihilate
70 fatal errors in authentication mode MBEDTLS_SSL_VERIFY_OPTIONAL and to
71 reflect bad EC curves within verification result.
72 * Fix bug that caused the modular inversion function to accept the invalid
73 modulus 1 and therefore to hang. Found by blaufish. #641.
74 * Fix incorrect sign computation in modular exponentiation when the base is
75 a negative MPI. Previously the result was always negative. Found by Guido
76 Vranken.
77 * Fix a numerical underflow leading to stack overflow in mpi_read_file()
78 that was triggered uppon reading an empty line. Found by Guido Vranken.

Simon Butchere4b3df52017-02-26 02:01:22 +000088 * Add checks to prevent signature forgeries for very large messages while
89 using RSA through the PK module in 64-bit systems. The issue was caused by
90 some data loss when casting a size_t to an unsigned int value in the
91 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
92 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG7cd7cf02016-12-08 17:08:44 +000093 * Fixed potential livelock during the parsing of a CRL in PEM format in
94 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
95 characters after the footer could result in the execution of an infinite
96 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
97 Microsoft.
Janos Follath8dbb35a2017-01-27 16:05:20 +000098 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
99 when verifying the validity of a key on secp224k1. This could be
100 triggered remotely for example with a maliciously constructed certificate
Simon Butcher3ea1af22017-02-28 18:47:27 +0000101 and potentially could lead to remote code execution on some platforms.
Simon Butcherbd6882b2017-03-07 12:37:14 +0000102 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
103 team. #569 CVE-2017-2784

Andres AG8136e822016-12-09 17:26:23 +0000106 * Fix output certificate verification flags set by x509_crt_verify_top() when
107 traversing a chain of trusted CA. The issue would cause both flags,
108 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
109 set when the verification conditions are not met regardless of the cause.
110 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcher0f862942017-02-02 13:08:37 +0000111 * Fix the redefinition of macro ssl_set_bio to an undefined symbol

Andres AG8efc7692016-12-15 17:01:16 +0000117 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
118 would compare 64 bits of the record counter instead of 48 bits as indicated
119 in RFC 6347 Section 4.3.1. This could cause the execution of the
120 renegotiation routines at unexpected times when the protocol is DTLS. Found
121 by wariua. #687
Andres AGc6559722016-10-24 11:23:36 +0100122 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

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

1753 * Major argument / variable rewrite. Introduced use of size_t
1754 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001755 better unsigned / signed use. Renamed internal bigint types
1756 t_int and t_dbl to t_uint and t_udbl in the process

1760 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001761 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001762 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1763 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001764 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1765 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1766 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1767 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001768 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
