"Nonce-Disrespecting Adversaries Practical Forgery Attacks on GCM in - TLS" - H. Bock, A. Zauner, S. Devlin, J. Somorovsky, P. Jovanovic. - https://eprint.iacr.org/2016/475.pdf - * Fixed potential stack corruption in mbedtls_x509write_crt_der() and - mbedtls_x509write_csr_der() when the signature is copied to the buffer - without checking whether there is enough space in the destination. The - issue cannot be triggered remotely. Found by Jethro Beekman. - -Features - * Added support for CMAC for AES and 3DES and AES-CMAC-PRF-128, as defined by - NIST SP 800-38B, RFC-4493 and RFC-4615. - * Added hardware entropy selftest to verify that the hardware entropy source - is functioning correctly. - * Added a script to print build environment info for diagnostic use in test - scripts, which is also now called by all.sh. - * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to - configure the maximum length of a file path that can be buffered when - calling mbedtls_x509_crt_parse_path(). - * Added a configuration file config-no-entropy.h that configures the subset of - library features that do not require an entropy source. - * Added the macro MBEDTLS_ENTROPY_MIN_HARDWARE in config.h. This allows users - to configure the minimum number of bytes for entropy sources using the - mbedtls_hardware_poll() function. - -Bugfix - * Fix for platform time abstraction to avoid dependency issues where a build - may need time but not the standard C library abstraction, and added - configuration consistency checks to check_config.h - * Fix dependency issue in Makefile to allow parallel builds. - * Fix incorrect handling of block lengths in crypt_and_hash.c sample program, - when GCM is used. Found by udf2457. #441 - * Fix for key exchanges based on ECDH-RSA or ECDH-ECDSA which weren't - enabled unless others were also present. Found by David Fernandez. #428 - * Fix for out-of-tree builds using CMake. Found by jwurzer, and fix based on - a contribution from Tobias Tangemann. #541 - * Fixed cert_app.c sample program for debug output and for use when no root - certificates are provided. - * Fix conditional statement that would cause a 1 byte overread in - mbedtls_asn1_get_int().

Found by teumas. #513 - * Fix compilation without MBEDTLS_SELF_TEST enabled. - -Changes - * Extended test coverage of special cases, and added new timing test suite. - * Removed self-tests from the basic-built-test.sh script, and added all - missing self-tests to the test suites, to ensure self-tests are only - executed once. - * Added support for 3 and 4 byte lengths to mbedtls_asn1_write_len(). - * Added support for a Yotta specific configuration file - - through the symbol YOTTA_CFG_MBEDTLS_TARGET_CONFIG_FILE. - * Added optimization for code space for X.509/OID based on configured - features. Contributed by Aviv Palivoda. - * Renamed source file library/net.c to library/net_sockets.c to avoid - naming collision in projects which also have files with the common name - net.c. For consistency, the corresponding header file, net.h, is marked as - deprecated, and its contents moved to net_sockets.h. - * Changed the strategy for X.509 certificate parsing and validation, to no - longer disregard certificates with unrecognised fields. - -= mbed TLS 2.3.0 branch released 2016-06-28 - -Security - * Fix missing padding length check in mbedtls_rsa_rsaes_pkcs1_v15_decrypt - required by PKCS1 v2.2 - * Fix potential integer overflow to buffer overflow in - mbedtls_rsa_rsaes_pkcs1_v15_encrypt and mbedtls_rsa_rsaes_oaep_encrypt - (not triggerable remotely in (D)TLS). - * Fix a potential integer underflow to buffer overread in - mbedtls_rsa_rsaes_oaep_decrypt.

more (at the expense of performance) MBEDTLS_SHA256_SMALLER. - -= mbed TLS 1.3 branch - -Security - * With authmode set to SSL_VERIFY_OPTIONAL, verification of keyUsage and - extendedKeyUsage on the leaf certificate was lost (results not accessible -
