11Security
Simon Butcher7346a7e2017-02-26 02:01:49 +000012 * Add checks to prevent signature forgeries for very large messages while
13 using RSA through the PK module in 64-bit systems. The issue was caused by
14 some data loss when casting a size_t to an unsigned int value in the
15 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
16 pk_sign(). Found by Jean-Philippe Aumasson.
Andres AGe5671012016-12-08 17:08:44 +000017 * Fixed potential livelock during the parsing of a CRL in PEM format in
18 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
19 characters after the footer could result in the execution of an infinite
20 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
21 Microsoft.
Janos Follathf5ffc792017-01-27 16:05:20 +000022 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
23 when verifying the validity of a key on secp224k1. This could be
24 triggered remotely for example with a maliciously constructed certificate
Simon Butcher866a4472017-02-28 18:47:27 +000025 and potentially could lead to remote code execution on some platforms.
Simon Butcher2e5318e2017-03-07 12:46:05 +000026 Reported independently by rongsaws and Aleksandar Nikolic, Cisco Talos

29Bugfix
Andres AG2f3fe702017-01-20 17:07:46 +000030 * Fix output certificate verification flags set by x509_crt_verify_top() when
31 traversing a chain of trusted CA. The issue would cause both flags,
32 BADCERT_NOT_TRUSTED and BADCERT_EXPIRED, to be set when the verification
33 conditions are not met regardless of the cause. Found by Harm Verhagen and
34 inestlerode. #665 #561
Andres AGd3cbc152016-10-24 11:23:36 +010035 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing
Andres AGfada2e92016-10-24 14:31:54 +010036 the input string in PEM format to extract the different components. Found

Simon Butcherbb4bebc2017-03-10 20:31:09 +000041 * Fixed potential arithmetic overflow in ctr_drbg_reseed() that could cause
42 buffer bound checks to be bypassed. Found by Eyal Itkin.
43 * Fixed potential arithmetic overflows in cipher_update() that could cause
44 buffer bound checks to be bypassed. Found by Eyal Itkin.
45 * Fixed potential arithmetic overflow in md2_update() that could cause buffer
46 bound checks to be bypassed. Found by Eyal Itkin.
47 * Fixed potential arithmetic overflow in base64_decode() that could cause
48 buffer bound checks to be bypassed. Found by Eyal Itkin.
Andres AG03af0e02017-01-23 14:58:27 +000049 * Fix potential memory leak in x509_crl_parse(). The leak was caused by
50 missing calls to pem_free() in cases when a
Simon Butcherbfef0ce2017-02-28 16:36:22 +000051 POLARSSL_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
52 fix proposed by Guido Vranken. #722
Simon Butcherdccf7432017-03-02 09:18:09 +000053 * Fixed the templates used to generate project and solution files for Visual
54 Studio 2015 as well as the files themselves, to remove a build warning
55 generated in Visual Studio 2015. Reported by Steve Valliere. #742
Andres AG2b2fc112017-03-01 14:04:08 +000056 * Fix 1 byte buffer overflow in mpi_write_string() when the MPI number to
57 write in hexadecimal is negative and requires an odd number of digits.
58 Found and fixed by Guido Vranken.
Simon Butchera42044d2017-03-07 19:35:49 +000059 * Fix unlisted DES configuration dependency in some pkparse test cases. Found
60 by inestlerode. #555

Simon Butcherfd8d7992016-10-16 00:48:37 +010065 * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
66 with RFC-5116 and could lead to session key recovery in very long TLS
67 sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in

78 valid version in the trusted certificate list.
Simon Butcherfd8d7992016-10-16 00:48:37 +010079 * Fix incorrect handling of block lengths in crypt_and_hash.c sample program,
80 when GCM is used. Found by udf2457. #441
Simon Butcher2491fa22016-09-05 11:21:58 +030081 * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't

Paul Bakkerb6ecaf52011-04-19 14:29:23 +00001429Features
1430 * Added additional Cipher Block Modes to symmetric ciphers
1431 (AES CTR, Camellia CTR, XTEA CBC) including the option to
Paul Bakkera35aa542013-03-06 17:06:21 +01001432 enable and disable individual modes when needed
Paul Bakker335db3f2011-04-25 15:28:35 +00001433 * Functions requiring File System functions can now be disabled
1434 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001435 * A error_strerror function() has been added to translate between
1436 error codes and their description.
Paul Bakker2f5947e2011-05-18 15:47:11 +00001437 * Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
1438 functions.

1442 * Major argument / variable rewrite. Introduced use of size_t
1443 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001444 better unsigned / signed use. Renamed internal bigint types
1445 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +00001446 * mpi_init() and mpi_free() now only accept a single MPI
1447 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +00001448 * The error codes have been remapped and combining error codes
1449 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001450 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001451 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1452 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001453 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1454 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1455 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1456 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001457 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
1458 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
Paul Bakkera35aa542013-03-06 17:06:21 +01001459 POLARSSL_ERR_NET_TRY_AGAIN

1474 does not zeroize memory in advance anymore. Use rsa_init()
Paul Bakkera35aa542013-03-06 17:06:21 +01001475 before parsing a key or keyfile!
