Simon Butchere4b3df52017-02-26 02:01:22 +00006 * Add checks to prevent signature forgeries for very large messages while
7 using RSA through the PK module in 64-bit systems. The issue was caused by
8 some data loss when casting a size_t to an unsigned int value in the
9 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
10 mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
Andres AG7cd7cf02016-12-08 17:08:44 +000011 * Fixed potential livelock during the parsing of a CRL in PEM format in
12 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
13 characters after the footer could result in the execution of an infinite
14 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
15 Microsoft.
Janos Follath8dbb35a2017-01-27 16:05:20 +000016 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
17 when verifying the validity of a key on secp224k1. This could be
18 triggered remotely for example with a maliciously constructed certificate
Simon Butcher3ea1af22017-02-28 18:47:27 +000019 and potentially could lead to remote code execution on some platforms.
20 Reported independently by rongsaws and Regina Wilson. #569 CVE-2017-2784
Andres AGc8925092017-01-19 11:24:33 +000021

Andres AG8136e822016-12-09 17:26:23 +000023 * Fix output certificate verification flags set by x509_crt_verify_top() when
24 traversing a chain of trusted CA. The issue would cause both flags,
25 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
26 set when the verification conditions are not met regardless of the cause.
27 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcher0f862942017-02-02 13:08:37 +000028 * Fix the redefinition of macro ssl_set_bio to an undefined symbol
29 mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
30 Found by omlib-lin. #673

Simon Butcheref3d4e42017-02-02 16:36:59 +000033 define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG8efc7692016-12-15 17:01:16 +000034 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
35 would compare 64 bits of the record counter instead of 48 bits as indicated
36 in RFC 6347 Section 4.3.1. This could cause the execution of the
37 renegotiation routines at unexpected times when the protocol is DTLS. Found
38 by wariua. #687
Andres AGc6559722016-10-24 11:23:36 +010039 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

51 Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
Andres AGf4cbe102016-12-08 17:19:21 +000052 * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
53 by missing calls to mbedtls_pem_free() in cases when a
Simon Butcher763e3272017-02-28 16:36:22 +000054 MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
55 fix proposed by Guido Vranken. #722
Simon Butcher9aabf6d2017-03-02 09:18:09 +000056 * Fixed the templates used to generate project and solution files for Visual
57 Studio 2015 as well as the files themselves, to remove a build warning
58 generated in Visual Studio 2015. Reported by Steve Valliere. #742
Ron Eldor8c5385e2017-01-29 18:51:35 +020059 * Fix a resource leak in ssl_cookie, when using MBEDTLS_THREADING_C.
60 Raised and fix suggested by Alan Gillingham in the mbed TLS forum. #771
Andres AGe0545c32017-01-06 13:17:35 +000061 * Fix 1 byte buffer overflow in mbedtls_mpi_write_string() when the MPI
62 number to write in hexadecimal is negative and requires an odd number of
63 digits. Found and fixed by Guido Vranken.

Simon Butcherc48b66b2015-10-05 10:18:17 +0100222 Found by Guido Vranken, Intelworks. Not exploitable remotely in the context
223 of TLS, but might be in other uses. On 32 bit machines, requires reading a
224 string of close to or larger than 1GB to exploit; on 64 bit machines, would
225 require reading a string of close to or larger than 2^62 bytes.
Simon Butchera45aa132015-10-05 00:26:36 +0100226 * Fix potential random memory allocation in mbedtls_pem_read_buffer()

228 Intelworks. Not triggerable remotely in TLS. Triggerable remotely if you
229 accept PEM data from an untrusted source.
230 * Fix possible heap buffer overflow in base64_encoded() when the input
231 buffer is 512MB or larger on 32-bit platforms. Found by Guido Vranken,
232 Intelworks. Not trigerrable remotely in TLS.
Manuel Pégourié-Gonnard24417f02015-09-28 18:09:45 +0200233 * Fix potential double-free if mbedtls_conf_psk() is called repeatedly on
Simon Butcherfec73a82015-10-05 10:40:31 +0100234 the same mbedtls_ssl_config object and memory allocation fails. Found by

273 (MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable cookie
274 callbacks set with mbedtls_ssl_conf_dtls_cookies()), this will be
275 detected and mbedtls_ssl_read() will return

Manuel Pégourié-Gonnard06939ce2015-05-11 11:25:46 +0200360 should generally be the first function called on this context after init:

378 mbedtls_ssl_set_hs_ca_chain()
379 mbedtls_ssl_set_hs_psk()
Manuel Pégourié-Gonnardcaace652015-05-11 09:57:11 +0200380 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
Manuel Pégourié-Gonnardbc2b7712015-05-06 11:14:19 +0100381 using mbedtls_ssl_set_hostname().
Manuel Pégourié-Gonnard01e5e8c2015-05-11 10:11:56 +0200382 * mbedtls_ssl_conf_session_cache() changed prototype (only one context

398 mbedtls_base64_decode()
399 mbedtls_mpi_write_string()
400 mbedtls_dhm_calc_secret()

Manuel Pégourié-Gonnarda958d692015-03-27 10:23:53 +0100411 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
412 available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
413 * Test certificates in certs.c are no longer guaranteed to be nul-terminated
Manuel Pégourié-Gonnard75f90102015-03-27 09:56:18 +0100414 strings; use the new *_len variables instead of strlen().
Manuel Pégourié-Gonnard43b37cb2015-05-12 11:20:10 +0200415 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
416 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
417 length parameter to include the terminating null byte for PEM input.

1675 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001676 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001677 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1678 net_recv() now returns 0 on EOF instead of
