1mbed TLS ChangeLog (Sorted per branch, date) 2 3= mbed TLS 2.4.0 branch released 2016-10-17 4 5Security 6 * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant 7 with RFC-5116 and could lead to session key recovery in very long TLS 8 sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in 9 TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic. 10 https://eprint.iacr.org/2016/475.pdf 11 * Fixed potential stack corruption in mbedtls_x509write_crt_der() and 12 mbedtls_x509write_csr_der() when the signature is copied to the buffer 13 without checking whether there is enough space in the destination. The 14 issue cannot be triggered remotely. Found by Jethro Beekman. 15 16Features 17 * Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128, as defined by 18 NIST SP 800-38B, RFC-4493 and RFC-4615. 19 * Added hardware entropy selftest to verify that the hardware entropy source 20 is functioning correctly. 21 * Added a script to print build environment info for diagnostic use in test 22 scripts, which is also now called by all.sh. 23 * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to 24 configure the maximum length of a file path that can be buffered when 25 calling mbedtls_x509_crt_parse_path(). 26 * Added a configuration file config-no-entropy.h that configures the subset of 27 library features that do not require an entropy source. 28 * Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This allows users 29 to configure the minimum number of bytes for entropy sources using the 30 mbedtls_hardware_poll() function. 31 32Bugfix 33 * Fix for platform time abstraction to avoid dependency issues where a build 34 may need time but not the standard C library abstraction, and added 35 configuration consistency checks to check_config.h 36 * Fix dependency issue in Makefile to allow parallel builds. 37 * Fix incorrect handling of block lengths in crypt_and_hash.c sample program, 38 when GCM is used. Found by udf2457. #441 39 * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't 40 enabled unless others were also present. Found by David Fernandez. #428 41 * Fix for out-of-tree builds using CMake. Found by jwurzer, and fix based on 42 a contribution from Tobias Tangemann. #541 43 * Fixed cert_app.c sample program for debug output and for use when no root 44 certificates are provided. 45 * Fix conditional statement that would cause a 1 byte overread in 46 mbedtls_asn1_get_int().

Found by teumas. #513 65 * Fix compilation without MBEDTLS_SELF_TEST enabled. 66 67Changes 68 * Extended test coverage of special cases, and added new timing test suite. 69 * Removed self-tests from the basic-built-test.sh script, and added all 70 missing self-tests to the test suites, to ensure self-tests are only 71 executed once. 72 * Added support for 3 and 4 byte lengths to mbedtls_asn1_write_len(). 73 * Added support for a Yotta specific configuration file - 74 through the symbol YOTTA_CFG_MBEDTLS_TARGET_CONFIG_FILE. 75 * Added optimization for code space for X.509/OID based on configured 76 features. Contributed by Aviv Palivoda. 77 * Renamed source file library/net.c to library/net_sockets.c to avoid 78 naming collision in projects which also have files with the common name 79 net.c. For consistency, the corresponding header file, net.h, is marked as 80 deprecated, and its contents moved to net_sockets.h. 81 * Changed the strategy for X.509 certificate parsing and validation, to no 82 longer disregard certificates with unrecognised fields. 83 84= mbed TLS 2.3.0 branch released 2016-06-28 85 86Security 87 * Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt 88 required by PKCS1 v2.2 89 * Fix potential integer overflow to buffer overflow in 90 mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt 91 (not triggerable remotely in (D)TLS). 92 * Fix a potential integer underflow to buffer overread in 93 mbedtls_rsa_rsaes_oaep_decrypt. It is not triggerable remotely in 94 SSL/TLS. 95 96Features 97 * Support for platform abstraction of the standard C library time() 98 function. 99 100Bugfix 101 * Fix bug in mbedtls_mpi_add_mpi() that caused wrong results when the three 102 arguments where the same (in-place doubling). Found and fixed by Janos 103 Follath. #309 104 * Fix potential build failures related to the 'apidoc' target, introduced 105 in the previous patch release. Found by Robert Scheck. #390 #391 106 * Fix issue in Makefile that prevented building using armar. #386 107 * Fix memory leak that occured only when ECJPAKE was enabled and ECDHE and 108 ECDSA was disabled in config.h . The leak didn't occur by default. 109 * Fix an issue that caused valid certificates to be rejected whenever an 110 expired or not yet valid certificate was parsed before a valid certificate 111 in the trusted certificate list. 112 * Fix bug in mbedtls_x509_crt_parse that caused trailing extra data in the 113 buffer after DER certificates to be included in the raw representation. 114 * Fix issue that caused a hang when generating RSA keys of odd bitlength 115 * Fix bug in mbedtls_rsa_rsaes_pkcs1_v15_encrypt that made null pointer 116 dereference possible. 117 * Fix issue that caused a crash if invalid curves were passed to 118 mbedtls_ssl_conf_curves. #373 119 * Fix issue in ssl_fork_server which was preventing it from functioning. #429 120 * Fix memory leaks in test framework 121 * Fix test in ssl-opt.sh that does not run properly with valgrind 122 * Fix unchecked calls to mmbedtls_md_setup(). Fix by Brian Murray. #502 123 124Changes 125 * On ARM platforms, when compiling with -O0 with GCC, Clang or armcc5, 126 don't use the optimized assembly for bignum multiplication. This removes 127 the need to pass -fomit-frame-pointer to avoid a build error with -O0. 128 * Disabled SSLv3 in the default configuration. 129 * Optimized mbedtls_mpi_zeroize() for MPI integer size. (Fix by Alexey 130 Skalozub). 131 * Fix non-compliance server extension handling. Extensions for SSLv3 are now 132 ignored, as required by RFC6101. 133 134= mbed TLS 2.2.1 released 2016-01-05 135 136Security 137 * Fix potential double free when mbedtls_asn1_store_named_data() fails to 138 allocate memory. Only used for certificate generation, not triggerable 139 remotely in SSL/TLS. Found by Rafał Przywara. #367 140 * Disable MD5 handshake signatures in TLS 1.2 by default to prevent the 141 SLOTH attack on TLS 1.2 server authentication (other attacks from the 142 SLOTH paper do not apply to any version of mbed TLS or PolarSSL). 143 https://www.mitls.org/pages/attacks/SLOTH 144 145Bugfix 146 * Fix over-restrictive length limit in GCM. Found by Andreas-N. #362 147 * Fix bug in certificate validation that caused valid chains to be rejected 148 when the first intermediate certificate has pathLenConstraint=0. Found by 149 Nicholas Wilson. Introduced in mbed TLS 2.2.0. #280 150 * Removed potential leak in mbedtls_rsa_rsassa_pkcs1_v15_sign(), found by 151 JayaraghavendranK. #372 152 * Fix suboptimal handling of unexpected records that caused interop issues 153 with some peers over unreliable links. Avoid dropping an entire DTLS 154 datagram if a single record in a datagram is unexpected, instead only 155 drop the record and look at subsequent records (if any are present) in 156 the same datagram. Found by jeannotlapin. #345 157 158= mbed TLS 2.2.0 released 2015-11-04 159 160Security 161 * Fix potential double free if mbedtls_ssl_conf_psk() is called more than 162 once and some allocation fails. Cannot be forced remotely. Found by Guido 163 Vranken, Intelworks. 164 * Fix potential heap corruption on Windows when 165 mbedtls_x509_crt_parse_path() is passed a path longer than 2GB. Cannot be 166 triggered remotely. Found by Guido Vranken, Intelworks. 167 * Fix potential buffer overflow in some asn1_write_xxx() functions. 168 Cannot be triggered remotely unless you create X.509 certificates based 169 on untrusted input or write keys of untrusted origin. Found by Guido 170 Vranken, Intelworks. 171 * The X509 max_pathlen constraint was not enforced on intermediate 172 certificates. Found by Nicholas Wilson, fix and tests provided by 173 Janos Follath. #280 and #319 174 175Features 176 * Experimental support for EC J-PAKE as defined in Thread 1.0.0. 177 Disabled by default as the specification might still change. 178 * Added a key extraction callback to accees the master secret and key 179 block. (Potential uses include EAP-TLS and Thread.) 180 181Bugfix 182 * Self-signed certificates were not excluded from pathlen counting, 183 resulting in some valid X.509 being incorrectly rejected. Found and fix 184 provided by Janos Follath. #319 185 * Fix build error with configurations where ECDHE-PSK is the only key 186 exchange. Found and fix provided by Chris Hammond. #270 187 * Fix build error with configurations where RSA, RSA-PSK, ECDH-RSA or 188 ECHD-ECDSA if the only key exchange. Multiple reports. #310 189 * Fixed a bug causing some handshakes to fail due to some non-fatal alerts 190 not being properly ignored. Found by mancha and Kasom Koht-arsa, #308 191 * mbedtls_x509_crt_verify(_with_profile)() now also checks the key type and 192 size/curve against the profile. Before that, there was no way to set a 193 minimum key size for end-entity certificates with RSA keys. Found by 194 Matthew Page of Scannex Electronics Ltd. 195 * Fix failures in MPI on Sparc(64) due to use of bad assembly code. 196 Found by Kurt Danielson. #292 197 * Fix typo in name of the extKeyUsage OID.

Not triggerable remotely. 219 * Fix potential buffer overflow in mbedtls_mpi_read_string(). 220 Found by Guido Vranken, Intelworks. Not exploitable remotely in the context 221 of TLS, but might be in other uses. On 32 bit machines, requires reading a 222 string of close to or larger than 1GB to exploit; on 64 bit machines, would 223 require reading a string of close to or larger than 2^62 bytes. 224 * Fix potential random memory allocation in mbedtls_pem_read_buffer() 225 on crafted PEM input data. Found and fix provided by Guido Vranken, 226 Intelworks. Not triggerable remotely in TLS.

Full list of renamings in scripts/data_files/rename-1.3-2.0.txt 351 * Renamings of fields inside structures, not covered by the previous list: 352 mbedtls_cipher_info_t.key_length -> key_bitlen 353 mbedtls_cipher_context_t.key_length -> key_bitlen 354 mbedtls_ecp_curve_info.size -> bit_size 355 * Headers are now found in the 'mbedtls' directory (previously 'polarssl'). 356 * The following _init() functions that could return errors have 357 been split into an _init() that returns void and another function that 358 should generally be the first function called on this context after init: 359 mbedtls_ssl_init() -> mbedtls_ssl_setup() 360 mbedtls_ccm_init() -> mbedtls_ccm_setkey() 361 mbedtls_gcm_init() -> mbedtls_gcm_setkey() 362 mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)() 363 mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed() 364 Note that for mbedtls_ssl_setup(), you need to be done setting up the 365 ssl_config structure before calling it. 366 * Most ssl_set_xxx() functions (all except ssl_set_bio(), ssl_set_hostname(), 367 ssl_set_session() and ssl_set_client_transport_id(), plus 368 ssl_legacy_renegotiation()) have been renamed to mbedtls_ssl_conf_xxx() 369 (see rename.pl and compat-1.3.h above) and their first argument's type 370 changed from ssl_context to ssl_config. 371 * ssl_set_bio() changed signature (contexts merged, order switched, one 372 additional callback for read-with-timeout). 373 * The following functions have been introduced and must be used in callback 374 implementations (SNI, PSK) instead of their *conf counterparts: 375 mbedtls_ssl_set_hs_own_cert() 376 mbedtls_ssl_set_hs_ca_chain() 377 mbedtls_ssl_set_hs_psk() 378 * mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now set 379 using mbedtls_ssl_set_hostname(). 380 * mbedtls_ssl_conf_session_cache() changed prototype (only one context 381 pointer, parameters reordered). 382 * On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in 383 place of mbedtls_ssl_conf_session_tickets() to enable session tickets. 384 * The SSL debug callback gained two new arguments (file name, line number). 385 * Debug modes were removed. 386 * mbedtls_ssl_conf_truncated_hmac() now returns void. 387 * mbedtls_memory_buffer_alloc_init() now returns void. 388 * X.509 verification flags are now an uint32_t. Affect the signature of: 389 mbedtls_ssl_get_verify_result() 390 mbedtls_x509_ctr_verify_info() 391 mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated) 392 mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated) 393 * The following functions changed prototype to avoid an in-out length 394 parameter: 395 mbedtls_base64_encode() 396 mbedtls_base64_decode() 397 mbedtls_mpi_write_string() 398 mbedtls_dhm_calc_secret() 399 * In the NET module, all "int" and "int *" arguments for file descriptors 400 changed type to "mbedtls_net_context *". 401 * net_accept() gained new arguments for the size of the client_ip buffer. 402 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now 403 return void. 404 * ecdsa_write_signature() gained an addtional md_alg argument and 405 ecdsa_write_signature_det() was deprecated. 406 * pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA. 407 * Last argument of x509_crt_check_key_usage() and 408 mbedtls_x509write_crt_set_key_usage() changed from int to unsigned. 409 * test_ca_list (from certs.h) is renamed to test_cas_pem and is only 410 available if POLARSSL_PEM_PARSE_C is defined (it never worked without). 411 * Test certificates in certs.c are no longer guaranteed to be nul-terminated 412 strings; use the new *_len variables instead of strlen(). 413 * Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(), 414 mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect the 415 length parameter to include the terminating null byte for PEM input. 416 * Signature of mpi_mul_mpi() changed to make the last argument unsigned 417 * calloc() is now used instead of malloc() everywhere. API of platform 418 layer and the memory_buffer_alloc module changed accordingly. 419 (Thanks to Mansour Moufid for helping with the replacement.) 420 * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION 421 (support for renegotiation now needs explicit enabling in config.h). 422 * Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and MBEDTLS_HAVE_TIME_DATE 423 in config.h 424 * net_connect() and net_bind() have a new 'proto' argument to choose 425 between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP. 426 Their 'port' argument type is changed to a string. 427 * Some constness fixes 428 429Removals 430 * Removed mbedtls_ecp_group_read_string(). Only named groups are supported. 431 * Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use 432 mbedtls_ecp_muladd(). 433 * Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file functions 434 (use generic functions from md.h) 435 * Removed mbedtls_timing_msleep().

Those headers are 456 not supposed to be included by users. 457 * Changed md_info_t into an opaque structure (use md_get_xxx() accessors). 458 * Changed pk_info_t into an opaque structure. 459 * Changed cipher_base_t into an opaque structure. 460 * Removed sig_oid2 and rename sig_oid1 to sig_oid in x509_crt and x509_crl. 461 * x509_crt.key_usage changed from unsigned char to unsigned int. 462 * Removed r and s from ecdsa_context 463 * Removed mode from des_context and des3_context 464 465Default behavior changes 466 * The default minimum TLS version is now TLS 1.0. 467 * RC4 is now blacklisted by default in the SSL/TLS layer, and excluded from the 468 default ciphersuite list returned by ssl_list_ciphersuites() 469 * Support for receiving SSLv2 ClientHello is now disabled by default at 470 compile time. 471 * The default authmode for SSL/TLS clients is now REQUIRED. 472 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is 473 enabled in the default configuration, this is only noticeable if using a 474 custom config.h 475 * Default DHM parameters server-side upgraded from 1024 to 2048 bits. 476 * A minimum RSA key size of 2048 bits is now enforced during ceritificate 477 chain verification. 478 * Negotiation of truncated HMAC is now disabled by default on server too. 479 * The following functions are

mbedtls_version_check_feature() 485 486Requirement changes 487 * The minimum MSVC version required is now 2010 (better C99 support). 488 * The NET layer now unconditionnaly relies on getaddrinfo() and select(). 489 * Compiler is required to support C99 types such as long long and uint32_t. 490 491API changes from the 1.4 preview branch 492 * ssl_set_bio_timeout() was removed, split into mbedtls_ssl_set_bio() with 493 new prototype, and mbedtls_ssl_set_read_timeout(). 494 * The following functions now return void: 495 mbedtls_ssl_conf_transport() 496 mbedtls_ssl_conf_max_version() 497 mbedtls_ssl_conf_min_version() 498 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface 499 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing 500 an example implementation, see mbedtls_timing_delay_context and 501 mbedtls_timing_set/get_delay(). 502 * With UDP sockets, it is no longer necessary to call net_bind() again 503 after a successful net_accept(). 504 505Changes 506 * mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now 507 thread-safe if MBEDTLS_THREADING_C is enabled. 508 * Reduced ROM fooprint of SHA-256 and added an option to reduce it even 509 more (at the expense of performance) MBEDTLS_SHA256_SMALLER. 510 511= mbed TLS 1.3 branch 512 513Security 514 * With authmode set to SSL_VERIFY_OPTIONAL, verification of keyUsage and 515 extendedKeyUsage on the leaf certificate was lost (results not accessible 516 via ssl_get_verify_results()). 517 * Add countermeasure against "Lucky 13 strikes back" cache-based attack, 518

targets and making 533 cross-compilation easier (thanks to Alon Bar-Lev). 534 * The benchmark program also prints heap usage for public-key primitives 535 if POLARSSL_MEMORY_BUFFER_ALLOC_C and POLARSSL_MEMORY_DEBUG are defined. 536 * New script ecc-heap.sh helps measuring the impact of ECC parameters on 537 speed and RAM (heap only for now) usage. 538 * New script memory.sh helps measuring the ROM and RAM requirements of two 539 reduced configurations (PSK-CCM and NSA suite B). 540 * Add config flag POLARSSL_DEPRECATED_WARNING (off by default) to produce 541 warnings on use of deprecated functions (with GCC and Clang only). 542 * Add config flag POLARSSL_DEPRECATED_REMOVED (off by default) to produce 543 errors on use of deprecated functions. 544 545Bugfix 546 * Fix compile

SHA-256 in some x509 programs (reported by 579 Gergely Budai). 580 * Fix bug related to ssl_set_curves(): the client didn't check that the 581 curve picked by the server was actually allowed. 582 583Changes 584 * Remove bias in mpi_gen_prime (contributed by Pascal Junod). 585 * Remove potential sources of timing variations (some contributed by Pascal 586 Junod). 587 * Options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16 are deprecated. 588 * Enabling POLARSSL_NET_C without POLARSSL_HAVE_IPV6 is deprecated. 589 * compat-1.2.h and openssl.h are deprecated. 590 * Adjusting/overriding CFLAGS and LDFLAGS with the make build system is now 591 more flexible (warning: OFLAGS is not used any more) (see the README) 592 (contributed by Alon Bar-Lev). 593 * ssl_set_own_cert() no longer calls pk_check_pair() since the 594 performance impact was bad for some users (this was introduced in 1.3.10). 595 * Move from SHA-1 to SHA-256 in example programs using signatures 596 (suggested by Thorsten Mühlfelder). 597 * Remove some unneeded inclusions of header files from the standard library 598 "minimize" others (eg use stddef.h if only size_t is needed). 599 * Change #include lines in test files to use double quotes instead of angle 600 brackets for uniformity with the rest of the code. 601 * Remove dependency on sscanf() in X.509 parsing modules. 602 603= mbed TLS 1.3.10 released 2015-02-09 604Security 605 * NULL pointer dereference in the buffer-based allocator when the buffer is 606 full and polarssl_free() is called (found by Mark Hasemeyer) 607 (only possible if POLARSSL_MEMORY_BUFFER_ALLOC_C is enabled, which it is 608 not by default). 609 * Fix remotely-triggerable uninitialised pointer dereference caused by 610 crafted X.509 certificate (TLS server is not affected if it doesn't ask for a 611 client certificate) (found using Codenomicon Defensics). 612 * Fix remotely-triggerable memory leak caused by crafted X.509 certificates 613 (TLS server is not affected if it doesn't ask for a client certificate) 614 (found using Codenomicon Defensics). 615 * Fix potential stack overflow while parsing crafted X.509

parsing signature_algorithm extension if none of the 658 key exchanges enabled needs certificates. This fixes a possible interop 659 issue with some servers when a zero-length extension was sent. (Reported 660 by Peter Dettman.) 661 * On a 0-length input, base64_encode() did not correctly set output length 662 (found by Hendrik van den Boogaard). 663 664Changes 665 * Use deterministic nonces

668 * ssl_set_own_cert() now returns an error on key-certificate mismatch. 669 * Forbid repeated extensions in X.509 certificates. 670 * debug_print_buf() now prints a text view in addition to hexadecimal. 671 * A specific error is now returned when there are ciphersuites in common 672 but none of them is usable due to external factors such as no certificate 673 with a suitable (extended)KeyUsage or curve or no PSK set. 674 * It is now possible to disable negotiation of truncated HMAC server-side 675 at runtime with ssl_set_truncated_hmac(). 676 * Example programs for SSL

defined but not POLARSSL_HAVE_TIME (found by Stephane Di Vito). 699 * Remove non-existent file from VS projects (found by Peter Vaskovic). 700 * ssl_read() could return non-application data records on server while 701 renegotation was pending, and on client when a HelloRequest was received. 702 * Server-initiated renegotiation would fail with non-blocking I/O if the 703 write callback returned WANT_WRITE when requesting renegotiation. 704 * ssl_close_notify() could send more than one message in some circumstances 705 with non-blocking I/O. 706 * Fix compiler warnings on iOS (found by Sander Niemeijer). 707 * x509_crt_parse() did not increase total_failed on PEM error 708 * Fix compile error with armcc in mpi_is_prime() 709 * Fix potential bad read in parsing ServerHello (found by Adrien 710 Vialletelle). 711 712Changes 713 * Ciphersuites using SHA-256 or SHA-384 now require TLS 1.x (there is no 714 standard defining how to use SHA-2 with SSL 3.0). 715 * Ciphersuites using RSA-PSK key exchange new require TLS 1.x (the spec is 716 ambiguous on how to encode some packets with SSL 3.0). 717 * Made buffer size in pk_write_(pub)key_pem() more dynamic, eg smaller if 718 RSA is disabled, larger if POLARSSL_MPI_MAX_SIZE is larger. 719 * ssl_read() now returns POLARSSL_ERR_NET_WANT_READ rather than 720 POLARSSL_ERR_SSL_UNEXPECTED_MESSAGE on harmless alerts. 721 * POLARSSL_MPI_MAX_SIZE now defaults to 1024 in order to allow 8192 bits 722 RSA keys. 723 * Accept spaces at end of line or end of buffer in base64_decode(). 724 * X.509 certificates with more than one AttributeTypeAndValue per 725 RelativeDistinguishedName are not accepted any more. 726 727= PolarSSL 1.3.8 released 2014-07-11 728Security 729 * Fix length checking for AEAD ciphersuites (found by Codenomicon). 730 It was

770 * Very small records were incorrectly rejected when truncated HMAC was in 771 use with some ciphersuites and versions (RC4 in all versions, CBC with 772 versions < TLS 1.1). 773 * Very large records using more than 224 bytes of padding were incorrectly 774 rejected with CBC-based ciphersuites and TLS >= 1.1 775 * Very large records using less padding could cause a buffer overread of up 776 to 32 bytes with CBC-based ciphersuites and TLS >= 1.1 777 * Restore ability to use a v1 cert as a CA if trusted locally. (This had 778 been removed in 1.3.6.) 779 * Restore ability to locally trust a self-signed cert that is not a proper 780 CA for use as an end entity certificate. (This had been removed in 781 1.3.6.) 782 * Fix preprocessor checks for bn_mul PPC asm (found by Barry K.
