+= mbed TLS 2.4.2 branch released 2017-03-08
|
|
|
+
|
|
|
+Security
|
|
|
+ * Add checks to prevent signature forgeries for very large messages while
|
|
|
+ using RSA through the PK module in 64-bit systems. The issue was caused by
|
|
|
+ some data loss when casting a size_t to an unsigned int value in the
|
|
|
+ functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
|
|
|
+ mbedtls_pk_sign(). Found by Jean-Philippe Aumasson.
|
|
|
+ * Fixed potential livelock during the parsing of a CRL in PEM format in
|
|
|
+ mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
|
|
|
+ characters after the footer could result in the execution of an infinite
|
|
|
+ loop. The issue can be triggered remotely. Found by Greg Zaverucha,
|
|
|
+ Microsoft.
|
|
|
+ * Removed MD5 from the allowed hash algorithms for CertificateRequest and
|
|
|
+ CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
|
|
|
+ Introduced by interoperability fix for #513.
|
|
|
+ * Fixed a bug that caused freeing a buffer that was allocated on the stack,
|
|
|
+ when verifying the validity of a key on secp224k1. This could be
|
|
|
+ triggered remotely for example with a maliciously constructed certificate
|
|
|
+ and potentially could lead to remote code execution on some platforms.
|
|
|
+ Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos
|
|
|
+ team. #569 CVE-2017-2784
|
|
|
+
|
|
|
+Bugfix
|
|
|
+ * Fix output certificate verification flags set by x509_crt_verify_top() when
|
|
|
+ traversing a chain of trusted CA. The issue would cause both flags,
|
|
|
+ MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
|
|
|
+ set when the verification conditions are not met regardless of the cause.
|
|
|
+ Found by Harm Verhagen and inestlerode. #665 #561
|
|
|
+ * Fix the redefinition of macro ssl_set_bio to an undefined symbol
|
|
|
+ mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
|
|
|
+ Found by omlib-lin. #673
|
|
|
+ * Fix unused variable/function compilation warnings in pem.c, x509_crt.c and
|
|
|
+ x509_csr.c that are reported when building mbed TLS with a config.h that
|
|
|
+ does not define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
|
|
|
+ * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
|
|
|
+ would compare 64 bits of the record counter instead of 48 bits as indicated
|
|
|
+ in RFC 6347 Section 4.3.1. This could cause the execution of the
|
|
|
+ renegotiation routines at unexpected times when the protocol is DTLS. Found
|
|
|
+ by wariua. #687
|
|
|
+ * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing
|
|
|
+ the input string in PEM format to extract the different components. Found
|
|
|
+ by Eyal Itkin.
|
|
|
+ * Fixed potential arithmetic overflow in mbedtls_ctr_drbg_reseed() that could
|
|
|
+ cause buffer bound checks to be bypassed. Found by Eyal Itkin.
|
|
|
+ * Fixed potential arithmetic overflows in mbedtls_cipher_update() that could
|
|
|
+ cause buffer bound checks to be bypassed. Found by Eyal Itkin.
|
|
|
+ * Fixed potential arithmetic overflow in mbedtls_md2_update() that could
|
|
|
+ cause buffer bound checks to be bypassed. Found by Eyal Itkin.
|
|
|
+ * Fixed potential arithmetic overflow in mbedtls_base64_decode() that could
|
|
|
+ cause buffer bound checks to be bypassed. Found by Eyal Itkin.
|
|
|
+ * Fixed heap overreads in mbedtls_x509_get_time(). Found by Peng
|
|
|
+ Li/Yueh-Hsun Lin, KNOX Security, Samsung Research America.
|
|
|
+ * Fix potential memory leak in mbedtls_x509_crl_parse(). The leak was caused
|
|
|
+ by missing calls to mbedtls_pem_free() in cases when a
|
|
|
+ MBEDTLS_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
|
|
|
+ fix proposed by Guido Vranken. #722
|
|
|
+ * Fixed the templates used to generate project and solution files for Visual
|
|
|
+ Studio 2015 as well as the files themselves, to remove a build warning
|
|
|
+ generated in Visual Studio 2015. Reported by Steve Valliere. #742
|
|
|
+ * Fix a resource leak in ssl_cookie, when using MBEDTLS_THREADING_C.
|
|
|
+ Raised and fix suggested by Alan Gillingham in the mbed TLS forum. #771
|
|
|
+ * Fix 1 byte buffer overflow in mbedtls_mpi_write_string() when the MPI
|
|
|
+ number to write in hexadecimal is negative and requires an odd number of
|
|
|
+ digits. Found and fixed by Guido Vranken.
|
|
|
+ * Fix unlisted DES configuration dependency in some pkparse test cases. Found
|
|
|
+ by inestlerode. #555

|
|
|
+Security
|
|
|
+ * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
|
|
|
+ with RFC-5116 and could lead to session key recovery in very long TLS
|
|
|
+ sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in

+ TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic.
|
|
|
+ https://eprint.iacr.org/2016/475.pdf
|
|
|
+ * Fixed potential stack corruption in mbedtls_x509write_crt_der() and
|
|
|
+ mbedtls_x509write_csr_der() when the signature is copied to the buffer
|
|
|
+ without checking whether there is enough space in the destination. The
|
|
|
+ issue cannot be triggered remotely. Found by Jethro Beekman.
|
|
|
+
|
|
|
+Features
|
|
|
+ * Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128, as defined by

|
|
|
+ configure the maximum length of a file path that can be buffered when
|
|
|
+ calling mbedtls_x509_crt_parse_path().
|
|
|
+ * Added a configuration file config-no-entropy.h that configures the subset of
|
|
|
+ library features that do not require an entropy source.
|
|
|
+ * Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This allows users
|
|
|
+ to configure the minimum number of bytes for entropy sources using the
|
|
|
+ mbedtls_hardware_poll() function.
|
|
|
+
|
|
|
+Bugfix
|
|
|
+ * Fix for platform time abstraction to avoid dependency issues where a build
|
|

|
|
|
+
|
|
|
+Changes
|
|
|
+ * Extended test coverage of special cases, and added new timing test suite.
|
|
|
+ * Removed self-tests from the basic-built-test.sh script, and added all
|
|
|

+Features
|
|
|
+ * Support for DTLS 1.0 and 1.2 (RFC 6347).
|
|
|
+ * Ability to override core functions from MDx, SHAx, AES and DES modules
|
|
|
+ with custom implementation (eg hardware accelerated), complementing the
|
|
|
+ ability to override the whole module.
|
|
|
+ * New server-side implementation of session tickets that rotate keys to
|
|
|
+ preserve forward secrecy, and allows sharing across multiple contexts.
|
|
|
+ * Added a concept of X.509 cerificate verification profile that controls
|
|
|
+ which algorithms and key sizes (curves for ECDSA) are acceptable.
|
|
|
+ * Expanded configurability of security parameters in the SSL module with
|
|
|
+ mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
|
|
|
+ * Introduced a concept of presets for SSL security-relevant configuration
|
|
|
+ parameters.
|
|
|
+
|
|
|
+API Changes
|
|
|
+ * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
|
|
|
+ You now need to link to all of them if you use TLS for example.
|
|
|
+ * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
|
|
|
+ Some names have been further changed to make them more consistent.
|
|
|
+ Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
|
|
|
+ provided. Full list of renamings in scripts/data_files/rename-1.3-2.0.txt
|
|
|
+ * Renamings of fields inside structures, not covered by the previous list:
|
|
|
+ mbedtls_cipher_info_t.key_length -> key_bitlen
|
|
|
+ mbedtls_cipher_context_t.key_length -> key_bitlen
|
|
|
+ mbedtls_ecp_curve_info.size -> bit_size
|
|
|
+ * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
|
|
|
+ * The following _init() functions that could return errors have
|
|
|
+ been split into an _init() that returns void and another function that
|
|
|
+ should generally be the first function called on this context after init:
|
|
|
+ mbedtls_ssl_init() -> mbedtls_ssl_setup()
|
|
|
+ mbedtls_ccm_init() -> mbedtls_ccm_setkey()
|
|
|
+ mbedtls_gcm_init() -> mbedtls_gcm_setkey()
|
|
|
+ mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
|
|
|
+ mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
|
|
|
+ Note that for mbedtls_ssl_setup(), you need to be done setting up the
|
|
|
+ ssl_config structure before calling it.
|
|
|
+ * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(),
|
|
|
+ ssl_set_session() and ssl_set_client_transport_id(), plus
|
|
|
+ ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx()
|
|
|
+ (see rename.pl and compat-1.3.h above) and their first argument's type
|
|
|
+ changed from ssl_context to ssl_config.
|
|
|
+ * ssl_set_bio() changed signature (contexts merged, order switched, one
|
|
|
+ additional callback for read-with-timeout).
|
|
|
+ * The following functions have been introduced and must be used in callback
|
|
|
+ implementations (SNI, PSK) instead of their *conf counterparts:
|
|
|
+ mbedtls_ssl_set_hs_own_cert()
|
|
|
+ mbedtls_ssl_set_hs_ca_chain()
|
|
|
+ mbedtls_ssl_set_hs_psk()
|
|
|
+ * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set
|
|
|
+ using mbedtls_ssl_set_hostname().
|
|
|
+ * mbedtls_ssl_conf_session_cache() changed prototype (only one context
|
|
|
+ pointer, parameters reordered).
|
|
|
+ * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
|
|
|
+ place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
|
|
|
+ * The SSL debug callback gained two new arguments (file name, line number).
|
|
|
+ * Debug modes were removed.
|
|
|
+ * mbedtls_ssl_conf_truncated_hmac() now returns void.
|
|
|
+ * mbedtls_memory_buffer_alloc_init() now returns void.
|
|
|
+ * X.509 verification flags are now an uint32_t. Affect the signature of:
|
|
|
+ mbedtls_ssl_get_verify_result()
|
|
|
+ mbedtls_x509_ctr_verify_info()
|
|
|
+ mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
|
|
|
+ mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
|
|
|
+ * The following functions changed prototype to avoid an in-out length
|
|
|
+ parameter:
|
|
|
+ mbedtls_base64_encode()
|
|
|
+ mbedtls_base64_decode()
|
|
|
+ mbedtls_mpi_write_string()
|
|
|
+ mbedtls_dhm_calc_secret()
|
|
|
+ * In the NET module, all "int" and "int *" arguments for file descriptors
|
|
|
+ changed type to "mbedtls_net_context *".
|
|
|
+ * net_accept() gained new arguments for the size of the client_ip buffer.
|
|
|
+ * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now
|
|
|
+ return void.
|
|
|
+ * ecdsa_write_signature() gained an addtional md_alg argument and
|
|
|
+ ecdsa_write_signature_det() was deprecated.
|
|
|
+ * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
|
|
|
+ * Last argument of x509_crt_check_key_usage() and
|
|
|
+ mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
|
|
|
+ * test_ca_list (from certs.h) is renamed to test_cas_pem and is only
|
|
|
+ available if POLARSSL_PEM_PARSE_C is defined (it never worked without).
|
|
|
+ * Test certificates in certs.c are no longer guaranteed to be nul-terminated
|
|
|
+ strings; use the new *_len variables instead of strlen().
|
|
|
+ * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
|
|
|
+ mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the
|
|
|
+ length parameter to include the terminating null byte for PEM input.
|
|
|
+ * Signature of mpi_mul_mpi() changed to make the last argument unsigned
|
|
|
+ * calloc() is now used instead of malloc() everywhere. API of platform
|
|
|
+ layer and the memory_buffer_alloc module changed accordingly.
|
|
|
+ (Thanks to Mansour Moufid for helping with the replacement.)
|
|
|
+ * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
|
|
|
+ (support for renegotiation now needs explicit enabling in config.h).
|
|
|
+ * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE
|
|
|
+ in config.h
|
|
|
+ * net_connect() and net_bind() have a new 'proto' argument to choose
|
|
|
+ between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
|
|
|
+ Their 'port' argument type is changed to a string.
|
|
|
+ * Some constness fixes
|
|
|
+
|
|
|
+Removals
|
|
|
+ * Removed mbedtls_ecp_group_read_string(). Only named groups are supported.
|
|
|
+ * Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use
|
|
|
+ mbedtls_ecp_muladd().
|
|
|
+ * Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions
|
|
|
+ (use generic functions from md.h)
|
|
|
+ * Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a custom
|
|
|
+ waiting function.
|
|
|
+ * Removed test DHM parameters from the test certs module.
|
|
|
+ * Removed the PBKDF2 module (use PKCS5).
|
|
|
+ * Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
|
|
|
+ * Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
|
|
|
+ * Removed openssl.h (very partial OpenSSL compatibility layer).
|
|
|
+ * Configuration options POLARSSL_HAVE_LONGLONG was removed (now always on).
|
|
|
+ * Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 have
|
|
|
+ been removed (compiler is required to support 32-bit operations).
|
|
|
+ * Configuration option POLARSSL_HAVE_IPV6 was removed (always enabled).
|
|
|
+ * Removed test program o_p_test, the script compat.sh does more.
|
|
|
+ * Removed test program ssl_test, superseded by ssl-opt.sh.
|
|
|
+ * Removed helper script active-config.pl
|
|
|
+
|
|
|
+New deprecations
|
|
|
+ * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
|
|
|
+ argument (allowing memory savings if HMAC is not used)
|
|
|
+
|
|
|
+Semi-API changes (technically public, morally private)
|
|
|
+ * Renamed a few headers to include _internal in the name. Those headers are
|
|
|
+ not supposed to be included by users.
|
|
|
+ * Changed md_info_t into an opaque structure (use md_get_xxx() accessors).
|
|
|
+ * Changed pk_info_t into an opaque structure.
|
|
|
+ * Changed cipher_base_t into an opaque structure.
|
|
|
+ * Removed sig_oid2 and rename sig_oid1 to sig_oid in x509_crt and x509_crl.
|
|
|
+ * x509_crt.key_usage changed from unsigned char to unsigned int.
|
|
|
+ * Removed r and s from ecdsa_context
|
|
|
+ * Removed mode from des_context and des3_context
|
|
|
+
|
|
|
+Default behavior changes
|
|
|
+ * The default minimum TLS version is now TLS 1.0.
|
|
|
+ * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the
|
|
|
+ default ciphersuite list returned by ssl_list_ciphersuites()
|
|
|
+ * Support for receiving SSLv2 ClientHello is now disabled by default at
|
|
|
+ compile time.
|
|
|
+ * The default authmode for SSL/TLS clients is now REQUIRED.
|
|
|
+ * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
|
|
|
+ enabled in the default configuration, this is only noticeable if using a
|
|
|
+ custom config.h
|
|
|
+ * Default DHM parameters server-side upgraded from 1024 to 2048 bits.
|
|
|
+ * A minimum RSA key size of 2048 bits is now enforced during ceritificate
|
|
|
+ chain verification.
|
|
|
+ * Negotiation of truncated HMAC is now disabled by default on server too.
|
|
|
+ * The following functions are now case-sensitive:
|
|
|
+ mbedtls_cipher_info_from_string()
|
|
|
+ mbedtls_ecp_curve_info_from_name()
|
|
|
+ mbedtls_md_info_from_string()

|
|
|
+ * The minimum MSVC version required is now 2010 (better C99 support).
|
|
|
+ * The NET layer now unconditionnaly relies on getaddrinfo() and select().
|
|
|
+ * Compiler is required to support C99 types such as long long and uint32_t.
|
|
|
+
|
|
|
+API changes from the 1.4 preview branch
|
|
|
+ * ssl_set_bio_timeout() was removed, split into mbedtls_ssl_set_bio() with
|
|
|
+ new prototype, and mbedtls_ssl_set_read_timeout().
|
|
|
+ * The following functions now return void:
|
|
|
+ mbedtls_ssl_conf_transport()
|
|
|
+ mbedtls_ssl_conf_max_version()
|
|
|
+ mbedtls_ssl_conf_min_version()
|
|
|
+ * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
|
|
|
+ instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
|
|
|
+ an example implementation, see mbedtls_timing_delay_context and
|
|
|
+ mbedtls_timing_set/get_delay().
|
|
|
+ * With UDP sockets, it is no longer necessary to call net_bind() again
|
|
|
+ after a successful net_accept().
|
|
|
+
|
|
|
+Changes
|
|
|
+ * mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now
|
|
|
+ thread-safe if MBEDTLS_THREADING_C is enabled.
|
|
|
+ * Reduced ROM fooprint of SHA-256 and added an option to reduce it even
|
|

|
|
|
+

|
+
|
|
|
+Changes
|
|
|

|
|
|
+ instead of int for buffer lengths and loop variables for
|
|
|
+ better unsigned / signed use. Renamed internal bigint types
|
|
|
+ t_int and t_dbl to t_uint and t_udbl in the process
|
|
|
+ * mpi_init() and mpi_free() now only accept a single MPI
|
|
|
+ argument and do not accept variable argument lists anymore.
|
|
|
+ * The error codes have been remapped and combining error codes
|
|
|
+ is now done with a PLUS instead of an OR as error codes
|
|
|
+ used are negative.
|
|
|
+ * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
|
|
|
+ net_recv() now returns 0 on EOF instead of
|
|
|
+ POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
|
|
|
+ POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
|
|
|
+ ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
|
|
|
+ after the handshake.
|
|
|
+ * Network functions now return POLARSSL_ERR_NET_WANT_READ or
|
|
|
+ POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
|
|
|
+ POLARSSL_ERR_NET_TRY_AGAIN

|
|
|
+ * Added test vectors for: AES-CBC, AES-CFB, DES-CBC and 3DES-CBC,
