Simon Butcher7346a7e2017-02-26 02:01:49 +000013 * Add checks to prevent signature forgeries for very large messages while
14 using RSA through the PK module in 64-bit systems. The issue was caused by
15 some data loss when casting a size_t to an unsigned int value in the
16 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
17 pk_sign(). Found by Jean-Philippe Aumasson.
Andres AGe5671012016-12-08 17:08:44 +000018 * Fixed potential livelock during the parsing of a CRL in PEM format in
19 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
20 characters after the footer could result in the execution of an infinite
21 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
22 Microsoft.
Janos Follathf5ffc792017-01-27 16:05:20 +000023 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
24 when verifying the validity of a key on secp224k1. This could be
25 triggered remotely for example with a maliciously constructed certificate
Simon Butcher866a4472017-02-28 18:47:27 +000026 and potentially could lead to remote code execution on some platforms.

32 traversing a chain of trusted CA. The issue would cause both flags,
33 BADCERT_NOT_TRUSTED and BADCERT_EXPIRED, to be set when the verification
34 conditions are not met regardless of the cause. Found by Harm Verhagen and
35 inestlerode. #665 #561

Andres AG03af0e02017-01-23 14:58:27 +000050 * Fix potential memory leak in x509_crl_parse(). The leak was caused by
51 missing calls to pem_free() in cases when a
Simon Butcherbfef0ce2017-02-28 16:36:22 +000052 POLARSSL_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
53 fix proposed by Guido Vranken. #722

55 Studio 2015 as well as the files themselves, to remove a build warning
56 generated in Visual Studio 2015. Reported by Steve Valliere. #742
Andres AG2b2fc112017-03-01 14:04:08 +000057 * Fix 1 byte buffer overflow in mpi_write_string() when the MPI number to
58 write in hexadecimal is negative and requires an odd number of digits.
59 Found and fixed by Guido Vranken.

Paul Bakkerb6ecaf52011-04-19 14:29:23 +00001430Features
1431 * Added additional Cipher Block Modes to symmetric ciphers
1432 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +01001433 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +00001434 * Functions requiring File System functions can now be disabled
1435 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001436 * A error_strerror function() has been added to translate between
1437 error codes and their description.
Paul Bakker2f5947e2011-05-18 15:47:11 +00001438 * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
1439 functions.

1443 * Major argument / variable rewrite. Introduced use of size_t
1444 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001445 better unsigned / signed use. Renamed internal bigint types
1446 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +00001447 * mpi_init() and mpi_free() now only accept a single MPI
1448 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +00001449 * The error codes have been remapped and combining error codes
1450 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001451 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001452 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1453 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001454 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1455 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1456 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1457 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001458 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
1459 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
Paul Bakkera35aa542013-03-06 17:06:21 +01001460 POLARSSL_ERR_NET_TRY_AGAIN

1473 displays actual bit size of the value.
Paul Bakker98675492011-03-26 13:17:12 +00001474 * x509parse_key() (and as a consequence x509parse_keyfile())
1475 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001476 before parsing a key or keyfile!
