- Update to 2.28.3:
Features
* Use HOSTCC (if it is set) when compiling C code during generation of the
configuration-independent files. This allows them to be generated when CC
is set for cross compilation.
* AES-NI is now supported with Visual Studio.
* AES-NI is now supported in 32-bit builds, or when MBEDTLS_HAVE_ASM is
disabled, when compiling with GCC or Clang or a compatible compiler for a
target CPU that supports the requisite instructions (for example gcc -m32
-msse2 -maes -mpclmul). (Generic x86 builds with GCC-like compilers still
require MBEDTLS_HAVE_ASM and a 64-bit target.)
Security
* MBEDTLS_AESNI_C, which is enabled by default, was silently ignored on
builds that couldn't compile the GCC-style assembly implementation (most
notably builds with Visual Studio), leaving them vulnerable to timing
side-channel attacks. There is now an intrinsics-based AES-NI
implementation as a fallback for when the assembly one cannot be used.
Bugfix
* Fix a build issue on Windows where the source and build directory could
not be on different drives (#5751).
* Fix possible integer overflow in mbedtls_timing_hardclock(), which
could cause a crash for certain platforms & compiler options.
* Fix IAR compiler warnings. Fixes #6924.
* Fix a bug in the build where directory names containing spaces were
causing generate_errors.pl to error out resulting in a build failure.
Fixes issue #6879.
* Fix compile error where MBEDTLS_RSA_C and MBEDTLS_X509_CRT_WRITE_C are
defined, but MBEDTLS_PK_RSA_ALT_SUPPORT is not defined. Fixes #3174.
* Fix a build issue when defining MBEDTLS_TIMING_ALT and MBEDTLS_SELF_TEST.
The library would not link if the user didn't provide an external self-test
function. The self-test is now provided regardless of the choice of
internal/alternative timing implementation. Fixes #6923.
* mbedtls_x509write_crt_set_serial() now explicitly rejects serial numbers
whose binary representation is longer than 20 bytes. This was already
forbidden by the standard (RFC5280 - section 4.1.2.2) and now it's being
enforced also at code level.
* Fix potential undefined behavior in mbedtls_mpi_sub_abs(). Reported by
Pascal Cuoq using TrustInSoft Analyzer in #6701; observed independently by
Aaron Ucko under Valgrind.
* Fix behavior of certain sample programs which could, when run with no
arguments, access uninitialized memory in some cases. Fixes #6700 (which
was found by TrustInSoft Analyzer during REDOCS'22) and #1120.
* Fix build errors in test programs when MBEDTLS_CERTS_C is disabled.
Fixes #6243.
* Fix parsing of X.509 SubjectAlternativeName extension. Previously,
malformed alternative name components were not caught during initial
certificate parsing, but only on subsequent calls to
mbedtls_x509_parse_subject_alt_name(). Fixes #2838.
* Fix bug in conversion from OID to string in
mbedtls_oid_get_numeric_string(). OIDs such as 2.40.0.25 are now printed
correctly.
* Reject OIDs with overlong-encoded subidentifiers when converting them to a
string.
* Reject OIDs with subidentifier values exceeding UINT_MAX. Such
subidentifiers can be valid, but Mbed TLS cannot currently handle them.
* Reject OIDs that have unterminated subidentifiers, or (equivalently) have
the most-significant bit set in their last byte.
* Silence a warning about an unused local variable in bignum.c on some
architectures. Fixes #7166.
* Silence warnings from clang -Wdocumentation about empty \retval
descriptions, which started appearing with Clang 15. Fixes #6960.
* Fix undefined behavior in mbedtls_ssl_read() and mbedtls_ssl_write() if
len argument is 0 and buffer is NULL.
Changes
* The C code follows a new coding style. This is transparent for users but
affects contributors and maintainers of local patches. For more
information, see
https://mbed-tls.readthedocs.io/en/latest/kb/how-to/rewrite-branch-for-coding-style/
* Changed the default MBEDTLS_ECP_WINDOW_SIZE from 6 to 2. As tested in
issue 6790, the correlation between this define and RSA decryption
performance has changed lately due to security fixes. To fix the
performance degradation when using default values the window was reduced
from 6 to 2, a value that gives the best or close to best results when
tested on Cortex-M4 and Intel i7.
