Andres AG939954c2016-12-08 17:08:44 +00006 * Fixed potential livelock during the parsing of a CRL in PEM format in
7 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
8 characters after the footer could result in the execution of an infinite
9 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
10 Microsoft.
Janos Follath182013f2016-10-25 10:50:22 +010011 * Removed MD5 from the allowed hash algorithms for CertificateRequest and
12 CertificateVerify messages, to prevent SLOTH attacks against TLS 1.2.
Simon Butcher0621b1f2017-02-05 16:48:47 +000013 Introduced by interoperability fix for #513.

Andres AG703990b2016-10-24 11:23:36 +010015Bugfix
Andres AGd1650662016-12-09 17:26:23 +000016 * Fix output certificate verification flags set by x509_crt_verify_top() when
17 traversing a chain of trusted CA. The issue would cause both flags,
18 MBEDTLS_X509_BADCERT_NOT_TRUSTED and MBEDTLS_X509_BADCERT_EXPIRED, to be
19 set when the verification conditions are not met regardless of the cause.
20 Found by Harm Verhagen and inestlerode. #665 #561
Simon Butcherd57c8f02017-02-02 13:08:37 +000021 * Fix the redefinition of macro ssl_set_bio to an undefined symbol
22 mbedtls_ssl_set_bio_timeout in compat-1.3.h, by removing it.
23 Found by omlib-lin. #673
Andres AGc0db5112016-12-07 15:05:53 +000024 * Fix unused variable/function compilation warnings in pem.c, x509_crt.c and
25 x509_csr.c that are reported when building mbed TLS with a config.h that
Simon Butchera333b3c2017-02-02 16:17:37 +000026 does not define MBEDTLS_PEM_PARSE_C. Found by omnium21. #562
Andres AG2196c7f2016-12-15 17:01:16 +000027 * Fix incorrect renegotiation condition in ssl_check_ctr_renegotiate() that
28 would compare 64 bits of the record counter instead of 48 bits as indicated
29 in RFC 6347 Section 4.3.1. This could cause the execution of the
30 renegotiation routines at unexpected times when the protocol is DTLS. Found
31 by wariua. #687
Andres AG703990b2016-10-24 11:23:36 +010032 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing

Simon Butcheref8fa012016-10-16 00:44:08 +010056 * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
57 with RFC-5116 and could lead to session key recovery in very long TLS
58 sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in
59 TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic.
60 https://eprint.iacr.org/2016/475.pdf

433 place of mbedtls_ssl_conf_session_tickets() to enable session tickets.
Manuel Pégourié-Gonnard96936682015-06-02 15:14:15 +0100434 * The SSL debug callback gained two new arguments (file name, line number).

Manuel Pégourié-Gonnard0a4fb092015-05-07 12:50:31 +0100548 * DTLS no longer hard-depends on TIMING_C, but uses a callback interface
549 instead, see mbedtls_ssl_set_timer_cb(), with the Timing module providing
550 an example implementation, see mbedtls_timing_delay_context and
Manuel Pégourié-Gonnard88d37852015-06-17 14:26:49 +0200551 mbedtls_timing_set/get_delay().

Paul Bakker03a30d32011-11-11 10:55:02 +00001632Features
1633 * Added ssl_session_reset() to allow better multi-connection pools of
Paul Bakker0e04d0e2011-11-27 14:46:59 +00001634 SSL contexts without needing to set all non-connection-specific
Paul Bakker6083fd22011-12-03 21:45:14 +00001635 data and pointers again. Adapted ssl_server to use this functionality.
1636 * Added ssl_set_max_version() to allow clients to offer a lower maximum
1637 supported version to a server to help buggy server implementations.
Paul Bakker7eb013f2011-10-06 12:37:39 +00001638 (Closes ticket #36)

1642 * Added a generic entropy accumulator that provides support for adding
Paul Bakkerc4909d92011-10-12 09:52:22 +00001643 custom entropy sources and added some generic and platform dependent
Paul Bakkerfbc09f32011-10-12 09:56:41 +00001644 entropy sources
Paul Bakkerb5a11ab2011-10-12 09:58:41 +00001645

1653 * Separated the ASN.1 parsing code from the X.509 specific parsing code.
Paul Bakkerfe3256e2011-11-25 12:11:43 +00001654 So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
1655 * Changed the defined key-length of DES ciphers in cipher.h to include the
Paul Bakkera3d195c2011-11-27 21:07:34 +00001656 parity bits, to prevent mistakes in copying data. (Closes ticket #33)
1657 * Loads of minimal changes to better support WINCE as a build target
Paul Bakkera35aa542013-03-06 17:06:21 +01001658 (Credits go to Marco Lizza)

Paul Bakkerfa1c5922011-10-06 14:18:49 +00001666 * Moved all examples programs to use the new entropy and CTR_DRBG
1667 * Added permissive certificate parsing to x509parse_crt() and
1668 x509parse_crtfile(). With permissive parsing the parsing does not stop on
Paul Bakker3329d1f2011-10-12 09:55:01 +00001669 encountering a parse-error. Beware that the meaning of return values has
1670 changed!
Paul Bakkercebdf172011-11-11 15:01:31 +00001671 * All error codes are now negative. Even on mermory failures and IO errors.

Paul Bakker4f5ae802011-12-04 22:10:28 +00001678 * Allowed X509 key usage parsing to accept 4 byte values instead of the
Paul Bakkerc50132d2011-12-05 14:38:36 +00001679 standard 1 byte version sometimes used by Microsoft. (Closes ticket #38)
Paul Bakkerc8ffbe72011-12-05 14:22:49 +00001680 * Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
Paul Bakkerfa1c5922011-10-06 14:18:49 +00001681 smaller than the hash length. (Closes ticket #41)
Paul Bakker968bc982011-07-27 17:03:00 +00001682 * If certificate serial is longer than 32 octets, serial number is now
Paul Bakker343a8702011-06-09 14:27:58 +00001683 appended with '....' after first 28 octets
1684 * Improved build support for s390x and sparc64 in bignum.h

1705 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakker1496d382011-05-23 12:07:29 +00001706 enable and disable individual modes when needed
Paul Bakkerb6ecaf52011-04-19 14:29:23 +00001707 * Functions requiring File System functions can now be disabled
Paul Bakker23986e52011-04-24 08:57:21 +00001708 by undefining POLARSSL_FS_IO
1709 * A error_strerror function() has been added to translate between

1721 argument and do not accept variable argument lists anymore.
1722 * The error codes have been remapped and combining error codes
1723 is now done with a PLUS instead of an OR as error codes
Paul Bakker831a7552011-05-18 13:32:51 +00001724 used are negative.
1725 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
Paul Bakkera35aa542013-03-06 17:06:21 +01001726 net_recv() now returns 0 on EOF instead of
Paul Bakker23986e52011-04-24 08:57:21 +00001727 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
Paul Bakker3efa5752011-04-01 12:23:26 +00001728 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
Paul Bakker9dcc3222011-03-08 14:16:06 +00001729 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1730 after the handshake.
1731 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
Paul Bakkere77db2e2011-03-25 14:01:32 +00001732 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
