mbedtls: update to 2.28.8.
pkgsrc changes:
- comment out python dependencies that seem required only for tests
already disabled in pkgsrc
- pkglint
Upstream changes (from ChangeLog):
= Mbed TLS 2.28.8 branch released 2024-03-28
Features
* AES-NI is now supported in Windows builds with clang and clang-cl.
Resolves #8372.
* Add pc files for pkg-config, e.g.:
pkg-config --cflags --libs (mbedtls|mbedcrypto|mbedx509)
Security
* Passing buffers that are stored in untrusted memory as arguments
to PSA functions is now secure by default.
The PSA core now protects against modification of inputs or exposure
of intermediate outputs during operations. This is currently implemented
by copying buffers.
This feature increases code size and memory usage. If buffers passed to
PSA functions are owned exclusively by the PSA core for the duration of
the function call (i.e. no buffer parameters are in shared memory),
copying may be disabled by setting MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS.
Note that setting this option will cause input-output buffer overlap to
be only partially supported (#3266).
Fixes CVE-2024-28960.
Bugfix
* Fix the build with CMake when Everest is enabled through
a user configuration file or the compiler command line. Fixes #8165.
* Fix an inconsistency between implementations and usages of `__cpuid`,
which mainly causes failures when building Windows target using
mingw or clang. Fixes #8334 & #8332.
* Correct initial capacities for key derivation algorithms: TLS12_PRF,
TLS12_PSK_TO_MS.
* Fix mbedtls_pk_get_bitlen() for RSA keys whose size is not a
multiple of 8. Fixes #868.
* Avoid segmentation fault caused by releasing not initialized
entropy resource in gen_key example. Fixes #8809.
* Fix missing bitflags in SSL session serialization headers. Their absence
allowed SSL sessions saved in one configuration to be loaded in a
different, incompatible configuration.
* Fix the restoration of the ALPN when loading serialized connection with
the mbedtls_ssl_context_load() API.
* Fully support arbitrary overlap between inputs and outputs of PSA
functions. Note that overlap is still only partially supported when
MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS is set (#3266).
Changes
* Use heap memory to allocate DER encoded public/private key.
This reduces stack usage significantly for writing a public/private
key to a PEM string.
* cmake: Use GnuInstallDirs to customize install directories
Replace custom LIB_INSTALL_DIR variable with standard CMAKE_INSTALL_LIBDIR
variable. For backward compatibility, set CMAKE_INSTALL_LIBDIR if
LIB_INSTALL_DIR is set.
= Mbed TLS 2.28.7 branch released 2024-01-26
Security
* Fix a timing side channel in private key RSA operations. This side channel
could be sufficient for an attacker to recover the plaintext. A local
attacker or a remote attacker who is close to the victim on the network
might have precise enough timing measurements to exploit this. It requires
the attacker to send a large number of messages for decryption. For
details, see "Everlasting ROBOT: the Marvin Attack", Hubert \
Kario. Reported
by Hubert Kario, Red Hat.
* Fix a failure to validate input when writing x509 extensions lengths which
could result in an integer overflow, causing a zero-length buffer to be
allocated to hold the extension. The extension would then be copied into
the buffer, causing a heap buffer overflow.
= Mbed TLS 2.28.6 branch released 2023-11-06
Changes
* Mbed TLS is now released under a dual Apache-2.0 OR GPL-2.0-or-later
license. Users may choose which license they take the code under.
= Mbed TLS 2.28.5 branch released 2023-10-05
Features
* The documentation of mbedtls_ecp_group now describes the optimized
representation of A for some curves. Fixes #8045.
Security
* Developers using mbedtls_pkcs5_pbes2() or mbedtls_pkcs12_pbe() should
review the size of the output buffer passed to this function, and note
that the output after decryption may include CBC padding. Consider moving
to the new functions mbedtls_pkcs5_pbes2_ext() or mbedtls_pkcs12_pbe_ext()
which checks for overflow of the output buffer and reports the actual
length of the output.
* Improve padding calculations in CBC decryption, NIST key unwrapping and
RSA OAEP decryption. With the previous implementation, some compilers
(notably recent versions of Clang and IAR) could produce non-constant
time code, which could allow a padding oracle attack if the attacker
has access to precise timing measurements.
* Fix a buffer overread when parsing short TLS application data records in
ARC4 or null-cipher cipher suites. Credit to OSS-Fuzz.
Bugfix
* Fix x509 certificate generation to conform to RFC 5480 / RFC 5758 when
using ECC key. The certificate was rejected by some crypto frameworks.
Fixes #2924.
* Fix some cases where mbedtls_mpi_mod_exp, RSA key construction or ECDSA
signature can silently return an incorrect result in low memory conditions.
* Fix IAR compiler warnings. Fixes #7873, #4300.
* Fix an issue when parsing an otherName subject alternative name into a
mbedtls_x509_san_other_name struct. The type-id of the otherName was not
copied to the struct. This meant that the struct had incomplete
information about the otherName SAN and contained uninitialized memory.
* Fix the detection of HardwareModuleName otherName SANs. These were being
detected by comparing the wrong field and the check was erroneously
inverted.
* Fix an error when MBEDTLS_ECDSA_SIGN_ALT is defined but not
MBEDTLS_ECDSA_VERIFY_ALT, causing ecdsa verify to fail. Fixes #7498.
* Functions in the ssl_cache module now return a negative MBEDTLS_ERR_xxx
error code on failure. Before, they returned 1 to indicate failure in
some cases involving a missing entry or a full cache.
Changes
* In configurations with ARIA or Camellia but not AES, the value of
MBEDTLS_CIPHER_BLKSIZE_MAX was 8, rather than 16 as the name might
suggest. This did not affect any library code, because this macro was
only used in relation with CMAC which does not support these ciphers.
Its value is now 16 if ARIA or Camellia are present. This may affect
application code that uses this macro.
= Mbed TLS 2.28.4 branch released 2023-08-04
Features
* Allow MBEDTLS_CONFIG_FILE and MBEDTLS_USER_CONFIG_FILE to be set by
setting the CMake variable of the same name at configuration time.
Bugfix
* Fix crypt_and_hash decryption fail when used with a stream cipher
mode of operation, due to the input not being a multiple of the block
size. Resolves #7417.
* Fix a bug where mbedtls_x509_string_to_names() would return success
when given a invalid name string, if it did not contain '=' or ','.
* Fix missing PSA initialization in sample programs when
MBEDTLS_USE_PSA_CRYPTO is enabled.
* Fix clang and armclang compilation error when targeting certain Arm
M-class CPUs (Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M23,
SecurCore SC000). Fixes #1077.
* Fixed an issue that caused compile errors when using CMake and the IAR
toolchain.
* Fix the build with MBEDTLS_PSA_INJECT_ENTROPY. Fixes #7516.
* Fix builds on Windows with clang.
* Fix compilation warnings in aes.c for certain combinations
of configuration options.
* Fix a compilation error on some platforms when including mbedtls/ssl.h
with all TLS support disabled. Fixes #6628.
Changes
* Update test data to avoid failures of unit tests after 2023-08-07, and
update expiring certififcates in the certs module.

Log message:
mbedtls: update to 2.28.3.
= Mbed TLS 2.28.3 branch released 2023-03-28
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.

Log message:
mbedtls: update to 2.28.2.
= Mbed TLS 2.28.2 branch released 2022-12-14
Security
* Fix potential heap buffer overread and overwrite in DTLS if
MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and
MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
* An adversary with access to precise enough information about memory
accesses (typically, an untrusted operating system attacking a secure
enclave) could recover an RSA private key after observing the victim
performing a single private-key operation if the window size used for the
exponentiation was 3 or smaller. Found and reported by Zili KOU,
Wenjian HE, Sharad Sinha, and Wei ZHANG. See "Cache Side-channel Attacks
and Defenses of the Sliding Window Algorithm in TEEs" - Design, Automation
and Test in Europe 2023.
Bugfix
* Fix a long-standing build failure when building x86 PIC code with old
gcc (4.x). The code will be slower, but will compile. We do however
recommend upgrading to a more recent compiler instead. Fixes #1910.
* Fix support for little-endian Microblaze when MBEDTLS_HAVE_ASM is defined.
Contributed by Kazuyuki Kimura to fix #2020.
* Use double quotes to include private header file psa_crypto_cipher.h.
Fixes 'file not found with <angled> include' error
when building with Xcode.
* Fix handling of broken symlinks when loading certificates using
mbedtls_x509_crt_parse_path(). Instead of returning an error as soon as a
broken link is encountered, skip the broken link and continue parsing
other certificate files. Contributed by Eduardo Silva in #2602.
* Fix a compilation error when using CMake with an IAR toolchain.
Fixes #5964.
* Fix bugs and missing dependencies when building and testing
configurations with only one encryption type enabled in TLS 1.2.
* Provide the missing definition of mbedtls_setbuf() in some configurations
with MBEDTLS_PLATFORM_C disabled. Fixes #6118, #6196.
* Fix compilation errors when trying to build with
PSA drivers for AEAD (GCM, CCM, Chacha20-Poly1305).
* Fix memory leak in ssl_parse_certificate_request() caused by
mbedtls_x509_get_name() not freeing allocated objects in case of error.
Change mbedtls_x509_get_name() to clean up allocated objects on error.
* Fix checks on PK in check_config.h for builds with PSA and RSA. This does
not change which builds actually work, only moving a link-time error to
an early check.
* Fix ECDSA verification, where it was not always validating the
public key. This bug meant that it was possible to verify a
signature with an invalid public key, in some cases. Reported by
Guido Vranken using Cryptofuzz in #4420.
* Fix a possible null pointer dereference if a memory allocation fails
in TLS PRF code. Reported by Michael Madsen in #6516.
* Fix a bug in which mbedtls_x509_crt_info() would produce non-printable
bytes when parsing certificates containing a binary RFC 4108
HardwareModuleName as a Subject Alternative Name extension. Hardware
serial numbers are now rendered in hex format. Fixes #6262.
* Fix bug in error reporting in dh_genprime.c where upon failure,
the error code returned by mbedtls_mpi_write_file() is overwritten
and therefore not printed.
* In the bignum module, operations of the form (-A) - (+A) or (-A) - (-A)
with A > 0 created an unintended representation of the value 0 which was
not processed correctly by some bignum operations. Fix this. This had no
consequence on cryptography code, but might affect applications that call
bignum directly and use negative numbers.
* Fix undefined behavior (typically harmless in practice) of
mbedtls_mpi_add_mpi(), mbedtls_mpi_add_abs() and mbedtls_mpi_add_int()
when both operands are 0 and the left operand is represented with 0 limbs.
* Fix undefined behavior (typically harmless in practice) when some bignum
functions receive the most negative value of mbedtls_mpi_sint. Credit
to OSS-Fuzz. Fixes #6597.
* Fix undefined behavior (typically harmless in practice) in PSA ECB
encryption and decryption.
