= mbed TLS 1.3.10 released 2015-02-09
|
|
Security
|
|
* NULL pointer dereference in the buffer-based allocator when the buffer is
|
|
full and polarssl_free() is called (found by Mark Hasemeyer)
|
|
(only possible if POLARSSL_MEMORY_BUFFER_ALLOC_C is enabled, which it is
|
|
not by default).
|
|
* Fix remotely-triggerable uninitialised pointer dereference caused by
|
|
crafted X.509 certificate (TLS server is not affected if it doesn't ask for a
|
|
client certificate) (found using Codenomicon Defensics).
|
|
* Fix remotely-triggerable memory leak caused by crafted X.509 certificates
|
|
(TLS server is not affected if it doesn't ask for a client certificate)
|
|
(found using Codenomicon Defensics).
|
|
* Fix potential stack overflow while parsing crafted X.509 certificates
|
|
(TLS server is not affected if it doesn't ask for a client certificate)
|
|
(found using Codenomicon Defensics).
|
|
* Fix timing difference that could theoretically lead to a
|
|
Bleichenbacher-style attack in the RSA and RSA-PSK key exchanges
|
|
(reported by Sebastian Schinzel).
|
|
|
|
Features
|
|
* Add support for FALLBACK_SCSV (draft-ietf-tls-downgrade-scsv).
|
|
* Add support for Extended Master Secret (draft-ietf-tls-session-hash).
|
|
* Add support for Encrypt-then-MAC (RFC 7366).
|
|
* Add function pk_check_pair() to test if public and private keys match.
|
|
* Add x509_crl_parse_der().
|
|
* Add compile-time option POLARSSL_X509_MAX_INTERMEDIATE_CA to limit the
|
|
length of an X.509 verification chain.
|
|
* Support for renegotiation can now be disabled at compile-time
|
|
* Support for 1/n-1 record splitting, a countermeasure against BEAST.
|
|
* Certificate selection based on signature hash, prefering SHA-1 over SHA-2
|
|
for pre-1.2 clients when multiple certificates are available.
|
|
* Add support for getrandom() syscall on recent Linux kernels with Glibc or
|
|
a compatible enough libc (eg uClibc).
|
|
* Add ssl_set_arc4_support() to make it easier to disable RC4 at runtime
|
|
while using the default ciphersuite list.
|
|
* Added new error codes and debug messages about selection of
|
|
ciphersuite/certificate.
|
|
|
|
Bugfix
|
|
* Stack buffer overflow if ctr_drbg_update() is called with too large
|
|
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
|
|
a multiple of POLARSSL_MEMORY_ALIGN_MULTIPLE (not triggerable remotely).
|
|
* User set CFLAGS were ignored by Cmake with gcc (introduced in 1.3.9, found
|
|
by Julian Ospald).
|
|
* Fix potential undefined behaviour in Camellia.
|
|
* Fix potential failure in ECDSA signatures when POLARSSL_ECP_MAX_BITS is a
|
|
multiple of 8 (found by Gergely Budai).
|
|
* Fix unchecked return code in x509_crt_parse_path() on Windows (found by
|
|
Peter Vaskovic).
|
|
* Fix assembly selection for MIPS64 (thanks to James Cowgill).
|
|
* ssl_get_verify_result() now works even if the handshake was aborted due
|
|
to a failed verification (found by Fredrik Axelsson).
|
|
* Skip writing and parsing signature_algorithm extension if none of the
|
|
key exchanges enabled needs certificates. This fixes a possible interop
|
|
issue with some servers when a zero-length extension was sent. (Reported
|
|
by Peter Dettman.)
|
|
* On a 0-length input, base64_encode() did not correctly set output length
|
|
(found by Hendrik van den Boogaard).
|
|
|
|
Changes
|
|
* Use deterministic nonces for AEAD ciphers in TLS by default (possible to
|
|
switch back to random with POLARSSL_SSL_AEAD_RANDOM_IV in config.h).
|
|
* Blind RSA private operations even when POLARSSL_RSA_NO_CRT is defined.
|
|
* ssl_set_own_cert() now returns an error on key-certificate mismatch.
|
|
* Forbid repeated extensions in X.509 certificates.
|
|
* debug_print_buf() now prints a text view in addition to hexadecimal.
|
|
* A specific error is now returned when there are ciphersuites in common
|
|
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.
|
|
* It is now possible to disable negotiation of truncated HMAC server-side
|
|
at runtime with ssl_set_truncated_hmac().
|
|
* Example programs for SSL client and server now disable SSLv3 by default.
|
|
* Example programs for SSL client and server now disable RC4 by default.
|
|
* Use platform.h in all test suites and programs.

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
|
|
(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
|
|
(not affected if ECC support was compiled out) (found using Codenomicon
|
|
Defensics).
|

|
|
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.
|
|
* Fix compiler warnings on iOS (found by Sander Niemeijer).
|
|
* x509_crt_parse() did not increase total_failed on PEM error
|
|
* Fix compile error with armcc in mpi_is_prime()
|
|

|
|
Vialletelle).
|
|
|
|
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).
|
|
* 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.
|
|
|
|
= PolarSSL 1.3.8 released 2014-07-11
|
|
Security
|
|
* Fix length checking for AEAD ciphersuites (found by Codenomicon).
|
|
It was possible to crash the server (and client) using crafted messages
|
|
when a GCM suite was chosen.
|
|
|
|

|
|
* Optimize for RAM usage in example config.h for NSA Suite B profile.

|
|
(ssl_set_renegotiation_enforced())
|
|

|
|
ciphersuites to use and save some memory if the list is small.
|
|
|
|
Changes
|
|
* Add LINK_WITH_PTHREAD option in CMake for explicit linking that is
|
|
required on some platforms (e.g. OpenBSD)
|
|
* Migrate zeroizing of data to polarssl_zeroize() instead of memset()
|
|
against unwanted compiler optimizations
|
|
* md_list() now returns hashes strongest first
|
|
* Selection of hash for signing ServerKeyExchange in TLS 1.2 now picks
|
|
strongest offered by client.

use with some ciphersuites and versions (RC4 in all versions, CBC with
|
|
versions < TLS 1.1).
|
|
* 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
|
|
interpret semicolons as comment delimiters (found by Barry K. Nathan).
|
|
* Fix off-by-one error in parsing Supported Point Format extension that
|
|
caused some handshakes to fail.
|
|
* Fix possible miscomputation of the premaster secret with DHE-PSK key

|
|
|
|
Changes
|

* x509_crt_info() now prints information about parsed extensions as well
|
|
* pk_verify() now returns a specific error code when the signature is valid

|
|
(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
|
|
certificate. If the user-supplied chain contains only one certificates,
|
|
it is not affected (ie, its notAfter date is properly checked).
|
|
* Prevent potential NULL pointer dereference in ssl_read_record() (found by

|
|
Shuo Chen).
|
|
* oid_get_numeric_string() used to truncate the output without returning an
|
|
error if the output buffer was just 1 byte too small.
|
|
* 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.
|
|
* Potential buffer overwrite in pem_write_buffer() because of low length
|
|
indication (found by Thijs Alkemade)
|
|
* 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).

|
|
Features
|
|
* Added ssl_session_reset() to allow better multi-connection pools of
|
|
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)
|
|

|
|
introspection functions (Closes ticket #40)
|
|
* Added CTR_DRBG based on AES-256-CTR (NIST SP 800-90) random generator
|
|
* Added a generic entropy accumulator that provides support for adding

|
|
entropy sources
|
|
|
|
Changes
|
|
* Documentation for AES and Camellia in modes CTR and CFB128 clarified.
|
|
* Fixed rsa_encrypt and rsa_decrypt examples to use public key for
|
|
encryption and private key for decryption. (Closes ticket #34)
|
|
* Inceased maximum size of ASN1 length reads to 32-bits.
|
|
* Added an EXPLICIT tag number parameter to x509_get_ext()
|
|
* Added a separate CRL entry extension parsing function
|
|
* Separated the ASN.1 parsing code from the X.509 specific parsing code.
|
|
So now there is a module that is controlled with POLARSSL_ASN1_PARSE_C.
|
|
* Changed the defined key-length of DES ciphers in cipher.h to include the
|
|
parity bits, to prevent mistakes in copying data. (Closes ticket #33)
|
|

|
|
(Credits go to Marco Lizza)
|
|
* Added POLARSSL_MPI_WINDOW_SIZE definition to allow easier time to memory

|
|
* 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
|
|
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)

|
|
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)
|
|
* If certificate serial is longer than 32 octets, serial number is now
|
|
appended with '....' after first 28 octets
|
|
* Improved build support for s390x and sparc64 in bignum.h
|
|
* Fixed MS Visual C++ name clash with int64 in sha4.h

|
|
Features
|
|
* Added additional Cipher Block Modes to symmetric ciphers
|
|
(AES CTR, Camellia CTR, XTEA CBC) including the option to
|
|
enable and disable individual modes when needed
|
|
* Functions requiring File System functions can now be disabled
|
|
by undefining POLARSSL_FS_IO
|
|
* A error_strerror function() has been added to translate between
|
|
error codes and their description.

|
|
functions.
|
|
* Added ssl_mail_client and ssl_fork_server as example programs.
|
|
|
|
Changes
|
|
* Major argument / variable rewrite. Introduced use of size_t
|
|
instead of int for buffer lengths and loop variables for
|
|
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
|
|
used are negative.
|
|
* Changed behaviour of net_read(), ssl_fetch_input() and ssl_recv().
|
|
net_recv() now returns 0 on EOF instead of
|
|
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
|
|
POLARSSL_ERR_NET_TRY_AGAIN
|
|
|
|

|
|
functionality as well.
|
|
* Added mpi_fill_random() for centralized filling of big numbers
|
|
with random data (Fixed ticket #10)
|
|
|
|
Changes
|
|
* Debug print of MPI now removes leading zero octets and
|
|
displays actual bit size of the value.
|
|
* x509parse_key() (and as a consequence x509parse_keyfile())
|
|
does not zeroize memory in advance anymore. Use rsa_init()
|
|
before parsing a key or keyfile!
|
|
|
|
Bugfix
|
|
* Debug output of MPI's now the same independent of underlying
|
|

be sent twice in non-blocking mode when send returns EAGAIN
|
|
* Fixed ssl_parse_client_hello(): session id and challenge must
|

|
|
ouput data is non-aligned by falling back to the software
|
|
implementation, as VIA Nehemiah cannot handle non-aligned buffers
|

|
|
serial number, setup correct server port in the ssl client example

|
|
peer may cause xyssl to loop indefinitely by sending a certificate
|
|
for which the RSA signature check fails (bug reported by Benoit)
