Simon Butcher7346a7e2017-02-26 02:01:49 +00006 * Add checks to prevent signature forgeries for very large messages while
7 using RSA through the PK module in 64-bit systems. The issue was caused by
8 some data loss when casting a size_t to an unsigned int value in the
9 functions rsa_verify_wrap(), rsa_sign_wrap(), rsa_alt_sign_wrap() and
10 pk_sign(). Found by Jean-Philippe Aumasson.
Andres AGe5671012016-12-08 17:08:44 +000011 * Fixed potential livelock during the parsing of a CRL in PEM format in
12 mbedtls_x509_crl_parse(). A string containing a CRL followed by trailing
13 characters after the footer could result in the execution of an infinite
14 loop. The issue can be triggered remotely. Found by Greg Zaverucha,
15 Microsoft.
Janos Follathf5ffc792017-01-27 16:05:20 +000016 * Fixed a bug that caused freeing a buffer that was allocated on the stack,
17 when verifying the validity of a key on secp224k1. This could be
18 triggered remotely for example with a maliciously constructed certificate
Simon Butcher866a4472017-02-28 18:47:27 +000019 and potentially could lead to remote code execution on some platforms.
20 Reported independently by rongsaws and Regina Wilson. #569 CVE-2017-2784
Andres AGf0a401f2016-12-07 16:08:04 +000021
22Bugfix
Andres AG2f3fe702017-01-20 17:07:46 +000023 * Fix output certificate verification flags set by x509_crt_verify_top() when
24 traversing a chain of trusted CA. The issue would cause both flags,
25 BADCERT_NOT_TRUSTED and BADCERT_EXPIRED, to be set when the verification
26 conditions are not met regardless of the cause. Found by Harm Verhagen and
27 inestlerode. #665 #561
Andres AGd3cbc152016-10-24 11:23:36 +010028 * Fixed multiple buffer overreads in mbedtls_pem_read_buffer() when parsing
Andres AGfada2e92016-10-24 14:31:54 +010029 the input string in PEM format to extract the different components. Found
Andres AGd3cbc152016-10-24 11:23:36 +010030 by Eyal Itkin.
Andres AGf0a401f2016-12-07 16:08:04 +000031 * Fix unused variable/function compilation warnings in pem.c and x509_csr.c
32 that are reported when building mbed TLS with a config.h that does not
Simon Butcherdf33a6a2017-02-02 16:53:50 +000033 define POLARSSL_PEM_PARSE_C. Found by omnium21. #562
Andres Amaya Garcia74ef6502017-01-18 13:56:58 +000034 * Fixed potential arithmetic overflow in mbedtls_ctr_drbg_reseed() that could
35 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
36 * Fixed potential arithmetic overflows in mbedtls_cipher_update() that could
37 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
38 * Fixed potential arithmetic overflow in mbedtls_md2_update() that could
39 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
Andres AG59abd302017-01-18 17:21:03 +000040 * Fixed potential arithmetic overflow in mbedtls_base64_decode() that could
41 cause buffer bound checks to be bypassed. Found by Eyal Itkin.
Andres AG03af0e02017-01-23 14:58:27 +000042 * Fix potential memory leak in x509_crl_parse(). The leak was caused by
43 missing calls to pem_free() in cases when a
Simon Butcherbfef0ce2017-02-28 16:36:22 +000044 POLARSSL_ERR_PEM_NO_HEADER_FOOTER_PRESENT error was encountered. Found and
45 fix proposed by Guido Vranken. #722
Simon Butcherdccf7432017-03-02 09:18:09 +000046 * Fixed the templates used to generate project and solution files for Visual
47 Studio 2015 as well as the files themselves, to remove a build warning
48 generated in Visual Studio 2015. Reported by Steve Valliere. #742
Andres AG2b2fc112017-03-01 14:04:08 +000049 * Fix 1 byte buffer overflow in mpi_write_string() when the MPI number to
50 write in hexadecimal is negative and requires an odd number of digits.
51 Found and fixed by Guido Vranken.

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

69 valid version in the trusted certificate list.
Simon Butcherfd8d7992016-10-16 00:48:37 +010070 * Fix incorrect handling of block lengths in crypt_and_hash.c sample program,

Paul Bakker335db3f2011-04-25 15:28:35 +00001424 * Functions requiring File System functions can now be disabled
1425 by undefining POLARSSL_FS_IO
Paul Bakker9d781402011-05-09 16:17:09 +00001426 * A error_strerror function() has been added to translate between

1433 * Major argument / variable rewrite. Introduced use of size_t
1434 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001435 better unsigned / signed use. Renamed internal bigint types
1436 t_int and t_dbl to t_uint and t_udbl in the process

1440 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001441 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001442 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1443 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001444 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1445 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1446 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1447 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001448 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
