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.

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

33 cause buffer bound checks to be bypassed. Found by Eyal Itkin.

35 cause buffer bound checks to be bypassed. Found by Eyal Itkin.

Simon Butcherfd8d7992016-10-16 00:48:37 +010044 * Removed the MBEDTLS_SSL_AEAD_RANDOM_IV option, because it was not compliant
45 with RFC-5116 and could lead to session key recovery in very long TLS
46 sessions. "Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in
47 TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic.

1421 * Major argument / variable rewrite. Introduced use of size_t
1422 instead of int for buffer lengths and loop variables for
Paul Bakkera35aa542013-03-06 17:06:21 +01001423 better unsigned / signed use. Renamed internal bigint types
1424 t_int and t_dbl to t_uint and t_udbl in the process
Paul Bakker6c591fa2011-05-05 11:49:20 +00001425 * mpi_init() and mpi_free() now only accept a single MPI
1426 argument and do not accept variable argument lists anymore.
Paul Bakker9d781402011-05-09 16:17:09 +00001427 * The error codes have been remapped and combining error codes
1428 is now done with a PLUS instead of an OR as error codes
Paul Bakkera35aa542013-03-06 17:06:21 +01001429 used are negative.
Paul Bakker831a7552011-05-18 13:32:51 +00001430 * Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
1431 net_recv() now returns 0 on EOF instead of
Paul Bakkera35aa542013-03-06 17:06:21 +01001432 POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
1433 POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
1434 ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
1435 after the handshake.
Paul Bakker831a7552011-05-18 13:32:51 +00001436 * Network functions now return POLARSSL_ERR_NET_WANT_READ or
1437 POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
Paul Bakkera35aa542013-03-06 17:06:21 +01001438 POLARSSL_ERR_NET_TRY_AGAIN
