case The actual input / output buffer overhead is only 301 instead of 512. This requires a proper check on the padding_idx to prevent out of bounds reads. Previously a remote party could potentially trigger an access error and thus stop the application when sending a malicious packet having MAX_CONTENT_LEN of data, 32 bytes of MAC and a decrypted padlen of . This would result in reading from in_ctr + 13 + 32 + MAX_CONTENT_LEN - 1 - 1 for 256 bytes (including fake padding check). Or 13 + 32 bytes over the buffer length. We now reset padding_idx to 0, if it's clear that it will never be a valid padding (padlen > msg_len || msg_len + padlen + 256 > buffer_len)

|
|
* Fixed generation of DHM parameters to correct length (found by Ruslan
|
|
Yushchenko)
|
|
|
|
= Version 1.1.1 released on 2012-01-23
|
|
Bugfix
|
|
* Check for failed malloc() in ssl_set_hostname() and x509_get_entries()
|
|
(Closes ticket #47, found by Hugo Leisink)
|
|
* Fixed issues with Intel compiler on 64-bit systems (Closes ticket #50)
|
|
* Fixed multiple compiler warnings for VS6 and armcc
|
|
* Fixed bug in CTR_CRBG selftest
|
|
|
|
= Version 1.1.0 released on 2011-12-22
|
|
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)
|
|
* Added cipher_get_cipher_mode() and cipher_get_cipher_operation()
|
|
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
|
|
custom entropy sources and added some generic and platform dependent
|
|
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)
|
|
* Loads of minimal changes to better support WINCE as a build target
|
|
(Credits go to Marco Lizza)
|
|
* Added POLARSSL_MPI_WINDOW_SIZE definition to allow easier time to memory
|
|
trade-off
|
|
* Introduced POLARSSL_MPI_MAX_SIZE and POLARSSL_MPI_MAX_BITS for MPI size
|
|
management (Closes ticket #44)
|
|
* Changed the used random function pointer to more flexible format. Renamed
|
|
havege_rand() to havege_random() to prevent mistakes. Lots of changes as
|
|
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
|
|
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)
|
|
* 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
|
|
* Corrected removal of leading "00:" in printing serial numbers in
|
|
certificates and CRLs
|
|
|
|
= Version 1.0.0 released on 2011-07-27
|
|
Features
|

|
|
* Added rsa_encrypt and rsa_decrypt simple example programs.

|
|
codes instead of integers
|
|
|
|
Bugfix

|
|
#18)
|
|
|
|
= Version 0.99-pre5 released on 2011-05-26
|
|
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.
|
|
* Added mpi_get_bit() and mpi_set_bit() individual bit setter/getter
|
|
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
|
|
|
|
= Version 0.99-pre4 released on 2011-04-01
|
|

|
|
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
|
|

|
|
|
|
= Version 0.6 released on 2007-04-01
|
|
|
|
* Ciphers used in SSL/TLS can now be disabled at compile
|
|
time, to reduce the memory footprint on embedded systems
|
|
* Added multiply assembly code for the TriCore and modified
|
|
havege_struct for this processor, thanks to David Patiño
|
|
* Added multiply assembly code for 64-bit PowerPCs,
|
|
thanks to Peking University and the OSU Open Source Lab
|
|
* Added experimental support of Quantum Cryptography
|
|
* Added support for autoconf, contributed by Arnaud Cornet
|
|
* Fixed "long long" compilation issues on IA-64 and PPC64
|
|
* Fixed a bug introduced in xyssl-0.5/timing.c: hardclock
|
|
was not being correctly defined on ARM and MIPS
|
|
|
|
= Version 0.5 released on 2007-03-01
|
|
|
|
* Added multiply assembly code for SPARC and Alpha
|
|
* Added (beta) support for non-blocking I/O operations
|
|
* Implemented session resuming and client authentication
|
|
* Fixed some portability issues on WinCE, MINIX 3, Plan9
|
|
(thanks to Benjamin Newman), HP-UX, FreeBSD and Solaris
|
|
* Improved the performance of the EDH key exchange
|
|
* Fixed a bug that caused valid packets with a payload
|
|
size of 16384 bytes to be rejected
|
|
|
|
= Version 0.4 released on 2007-02-01
|
|
|
|
* Added support for Ephemeral Diffie-Hellman key exchange
|
|
* Added multiply asm code for SSE2, ARM, PPC, MIPS and M68K
|
|
* Various improvement to the modular exponentiation code
|
|
* Rewrote the headers to generate the API docs with doxygen
|
|
* Fixed a bug in ssl_encrypt_buf (incorrect padding was
|
|
generated) and in ssl_parse_client_hello (max. client
|
|
version was not properly set), thanks to Didier Rebeix
|
|
* Fixed another bug in ssl_parse_client_hello: clients with
|
|
cipherlists larger than 96 bytes were incorrectly rejected
|
|
* Fixed a couple memory leak in x509_read.c
|
|
|
|
= Version 0.3 released on 2007-01-01
|
|
|
|
* Added server-side SSLv3 and TLSv1.0 support
|
|
* Multiple fixes to enhance the compatibility with g++,
|
|
thanks to Xosé Antón Otero Ferreira
|
|
* Fixed a bug in the CBC code, thanks to dowst; also,
|
|
the bignum code is no longer dependent on long long
|
|
* Updated rsa_pkcs1_sign to handle arbitrary large inputs
|
|
* Updated timing.c for improved compatibility with i386
|
|
and 486 processors, thanks to Arnaud Cornet
|
|
|
|
= Version 0.2 released on 2006-12-01
|
|
|
|
* Updated timing.c to support ARM and MIPS arch
|
|
* Updated the MPI code to support 8086 on MSVC 1.5
|
|
* Added the copyright notice at the top of havege.h
|
|
* Fixed a bug in sha2_hmac, thanks to newsoft/Wenfang Zhang
|
|
* Fixed a bug reported by Adrian Rüegsegger in x509_read_key
|
|
* Fixed a bug reported by Torsten Lauter in ssl_read_record
|
|
* Fixed a bug in rsa_check_privkey that would wrongly cause
|
|
valid RSA keys to be dismissed (thanks to oldwolf)
|
|
* Fixed a bug in mpi_is_prime that caused some primes to fail
|
|
the Miller-Rabin primality test
|
|
