= mbed TLS 1.3.10 released 2015-02-09
Security
* NULL pointer dereference in the buffer-based allocator when the buffer is
2015-01-28 14:02:38 +00:00
full and polarssl_free() is called (found by Mark Hasemeyer)

not by default).
2014-11-11 21:17:26 +00:00
* Fix remotely-triggerable uninitialised pointer dereference caused by
2014-11-12 00:25:31 +00:00
crafted X.509 certificate (TLS server is not affected if it doesn't ask for a
2014-11-11 21:17:26 +00:00
client certificate) (found using Codenomicon Defensics).
* Fix remotely-triggerable memory leak caused by crafted X.509 certificates

Bleichenbacher-style attack in the RSA and RSA-PSK key exchanges
(reported by Sebastian Schinzel).

2015-01-08 10:15:09 +00:00

add_len (found by Jean-Philippe Aumasson) (not triggerable remotely).
* Possible buffer overflow of length at most POLARSSL_MEMORY_ALIGN_MULTIPLE
if memory_buffer_alloc_init() was called with buf not aligned and len not
2015-01-14 15:59:23 +00:00
a multiple of POLARSSL_MEMORY_ALIGN_MULTIPLE (not triggerable remotely).

but none of them is usable due to external factors such as no certificate
with a suitable (extended)KeyUsage or curve or no PSK set.
2015-01-14 15:59:23 +00:00
* It is now possible to disable negotiation of truncated HMAC server-side
at runtime with ssl_set_truncated_hmac().

= PolarSSL 1.3.9 released 2014-10-20
Security
* Lowest common hash was selected from signature_algorithms extension in
TLS 1.2 (found by Darren Bane) (introduced in 1.3.8).
* Remotely-triggerable memory leak when parsing some X.509 certificates
2014-10-20 11:37:51 +00:00
(server is not affected if it doesn't ask for a client certificate)
(found using Codenomicon Defensics).
* Remotely-triggerable memory leak when parsing crafted ClientHello

are defined but not POLARSSL_HAVE_TIME (found by Stephane Di Vito).
* Remove non-existent file from VS projects (found by Peter Vaskovic).
* ssl_read() could return non-application data records on server while
renegotation was pending, and on client when a HelloRequest was received.
* Server-initiated renegotiation would fail with non-blocking I/O if the
write callback returned WANT_WRITE when requesting renegotiation.
* ssl_close_notify() could send more than one message in some circumstances
with non-blocking I/O.

Vialletelle).
2014-07-13 12:43:28 +00:00
Changes
* Ciphersuites using SHA-256 or SHA-384 now require TLS 1.x (there is no
standard defining how to use SHA-2 with SSL 3.0).
* Ciphersuites using RSA-PSK key exchange new require TLS 1.x (the spec is
ambiguous on how to encode some packets with SSL 3.0).
2014-07-21 14:37:15 +00:00
* Made buffer size in pk_write_(pub)key_pem() more dynamic, eg smaller if
RSA is disabled, larger if POLARSSL_MPI_MAX_SIZE is larger.
* ssl_read() now returns POLARSSL_ERR_NET_WANT_READ rather than
POLARSSL_ERR_SSL_UNEXPECTED_MESSAGE on harmless alerts.
* POLARSSL_MPI_MAX_SIZE now defaults to 1024 in order to allow 8192 bits
RSA keys.
* Accept spaces at end of line or end of buffer in base64_decode().
* X.509 certificates with more than one AttributeTypeAndValue per
RelativeDistinguishedName are not accepted any more.
2014-07-13 12:43:28 +00:00

Changes

required on some platforms (e.g. OpenBSD)

use with some ciphersuites and versions (RC4 in all versions, CBC with
versions < TLS 1.1).
2014-06-18 21:11:34 +00:00
* Very large records using more than 224 bytes of padding were incorrectly
rejected with CBC-based ciphersuites and TLS >= 1.1
* Very large records using less padding could cause a buffer overread of up
to 32 bytes with CBC-based ciphersuites and TLS >= 1.1
* Restore ability to use a v1 cert as a CA if trusted locally. (This had
been removed in 1.3.6.)
* Restore ability to locally trust a self-signed cert that is not a proper
CA for use as an end entity certificate. (This had been removed in
1.3.6.)
* Fix preprocessor checks for bn_mul PPC asm (found by Barry K. Nathan).
* Use \n\t rather than semicolons for bn_mul asm, since some assemblers

* Reject certificates with times not in UTC, per RFC 5280.
Security
* Avoid potential timing leak in ecdsa_sign() by blinding modular division.
(Found by Watson Ladd.)
* The notAfter date of some certificates was no longer checked since 1.3.5.
This affects certificates in the user-supplied chain except the top

error if the output buffer was just 1 byte too small.
2014-03-29 15:42:38 +00:00
* dhm_parse_dhm() (hence dhm_parse_dhmfile()) did not set dhm->len.
* Calling pk_debug() on an RSA-alt key would segfault.
* pk_get_size() and pk_get_len() were off by a factor 8 for RSA-alt keys.

indication (found by Thijs Alkemade)
2014-04-10 15:45:07 +00:00
* EC curves constants, which should be only in ROM since 1.3.3, were also
stored in RAM due to missing 'const's (found by Gergely Budai).

2014-02-05 14:54:34 +00:00
Security
* Forbid change of server certificate during renegotiation to prevent
2014-03-25 15:28:12 +00:00
"triple handshake" attack when authentication mode is 'optional' (the
attack was already impossible when authentication is required).
2014-03-10 12:15:18 +00:00

SSL contexts without needing to set all non-connection-specific
data and pointers again. Adapted ssl_server to use this functionality.
* Added ssl_set_max_version() to allow clients to offer a lower maximum
supported version to a server to help buggy server implementations.
(Closes ticket #36)

custom entropy sources and added some generic and platform dependent
entropy sources

encryption and private key for decryption. (Closes ticket #34)

* Added an EXPLICIT tag number parameter to x509_get_ext()
* Added a separate CRL entry extension parsing function

2013-03-06 16:06:21 +00:00
a consequence in library code and programs
* Moved all examples programs to use the new entropy and CTR_DRBG
* Added permissive certificate parsing to x509parse_crt() and
x509parse_crtfile(). With permissive parsing the parsing does not stop on
2013-03-06 16:06:21 +00:00
encountering a parse-error. Beware that the meaning of return values has
changed!
* All error codes are now negative. Even on mermory failures and IO errors.
Bugfix
* Fixed faulty HMAC-MD2 implementation. Found by dibac. (Closes
ticket #37)
* Fixed a bug where the CRL parser expected an EXPLICIT ASN.1 tag
before version numbers
* Allowed X509 key usage parsing to accept 4 byte values instead of the
standard 1 byte version sometimes used by Microsoft. (Closes ticket #38)
* Fixed incorrect behaviour in case of RSASSA-PSS with a salt length
smaller than the hash length. (Closes ticket #41)

appended with '....' after first 28 octets
* Improved build support for s390x and sparc64 in bignum.h

(AES CTR, Camellia CTR, XTEA CBC) including the option to
2013-03-06 16:06:21 +00:00
enable and disable individual modes when needed

functions.

instead of int for buffer lengths and loop variables for
2013-03-06 16:06:21 +00:00
better unsigned / signed use. Renamed internal bigint types
t_int and t_dbl to t_uint and t_udbl in the process
* mpi_init() and mpi_free() now only accept a single MPI
argument and do not accept variable argument lists anymore.
* The error codes have been remapped and combining error codes
is now done with a PLUS instead of an OR as error codes
2013-03-06 16:06:21 +00:00
used are negative.
* Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
net_recv() now returns 0 on EOF instead of
2013-03-06 16:06:21 +00:00
POLARSSL_ERR_NET_CONN_RESET. ssl_fetch_input() returns
POLARSSL_ERR_SSL_CONN_EOF on an EOF from its f_recv() function.
ssl_read() returns 0 if a POLARSSL_ERR_SSL_CONN_EOF is received
after the handshake.
* Network functions now return POLARSSL_ERR_NET_WANT_READ or
POLARSSL_ERR_NET_WANT_WRITE instead of the ambiguous
2013-03-06 16:06:21 +00:00
POLARSSL_ERR_NET_TRY_AGAIN

does not zeroize memory in advance anymore. Use rsa_init()
2013-03-06 16:06:21 +00:00
before parsing a key or keyfile!
Bugfix
* Debug output of MPI's now the same independent of underlying
platform (32-bit / 64-bit) (Fixes ticket #19, found by Mads
2013-03-06 16:06:21 +00:00
