Assemble changelog
Executed scripts/assemble_changelog.py and manually fixed style where it diverged from the instructions in ChangeLog.d/00README.md. Manually added ChangeLog.d/bugfix_PR3405 which didn't have the .txt extension as prescribed in ChangeLog.d/00README.md and deleted it afterwards. Signed-off-by: Janos Follath <janos.follath@arm.com>

mbed TLS ChangeLog (Sorted per branch, date)
|
||||
|
||||
= mbed TLS x.x.x branch released xxxx-xx-xx
|
||||
|
||||
Default behavior changes
|
||||
* In the experimental PSA secure element interface, change the encoding of
|
||||
key lifetimes to encode a persistence level and the location. Although C
|
||||
prototypes do not effectively change, code calling
|
||||
psa_register_se_driver() must be modified to pass the driver's location
|
||||
instead of the keys' lifetime. If the library is upgraded on an existing
|
||||
device, keys created with the old lifetime value will not be readable or
|
||||
removable through Mbed TLS after the upgrade.
|
||||
|
||||
Features
|
||||
* New functions in the error module return constant strings for
|
||||
high- and low-level error codes, complementing mbedtls_strerror()
|
||||
which constructs a string for any error code, including compound
|
||||
ones, but requires a writable buffer. Contributed by Gaurav Aggarwal
|
||||
in #3176.
|
||||
* The new utility programs/ssl/ssl_context_info prints a human-readable
|
||||
dump of an SSL context saved with mbedtls_ssl_context_save().
|
||||
* Add support for midipix, a POSIX layer for Microsoft Windows.
|
||||
* Add new mbedtls_x509_crt_parse_der_with_ext_cb() routine which allows
|
||||
parsing unsupported certificate extensions via user provided callback.
|
||||
Contributed by Nicola Di Lieto <nicola.dilieto@gmail.com> in #3243 as
|
||||
a solution to #3241.
|
||||
* Pass the "certificate policies" extension to the callback supplied to
|
||||
mbedtls_x509_crt_parse_der_with_ext_cb() if it contains unsupported
|
||||
policies (#3419).
|
||||
* Added support to entropy_poll for the kern.arandom syscall supported on
|
||||
some BSD systems. Contributed by Nia Alarie in #3423.
|
||||
* Add support for Windows 2000 in net_sockets. Contributed by opatomic. #3239
|
||||
|
||||
Security
|
||||
* Fix a side channel vulnerability in modular exponentiation that could
|
||||
reveal an RSA private key used in a secure enclave. Noticed by Sangho Lee,
|
||||
Ming-Wei Shih, Prasun Gera, Taesoo Kim and Hyesoon Kim (Georgia Institute
|
||||
of Technology); and Marcus Peinado (Microsoft Research). Reported by Raoul
|
||||
Strackx (Fortanix) in #3394.
|
||||
* Fix side channel in mbedtls_ecp_check_pub_priv() and
|
||||
mbedtls_pk_parse_key() / mbedtls_pk_parse_keyfile() (when loading a
|
||||
private key that didn't include the uncompressed public key), as well as
|
||||
mbedtls_ecp_mul() / mbedtls_ecp_mul_restartable() when called with a NULL
|
||||
f_rng argument. An attacker with access to precise enough timing and
|
||||
memory access information (typically an untrusted operating system
|
||||
attacking a secure enclave) could fully recover the ECC private key.
|
||||
Found and reported by Alejandro Cabrera Aldaya and Billy Brumley.
|
||||
* Fix issue in Lucky 13 counter-measure that could make it ineffective when
|
||||
hardware accelerators were used (using one of the MBEDTLS_SHAxxx_ALT
|
||||
macros). This would cause the original Lucky 13 attack to be possible in
|
||||
those configurations, allowing an active network attacker to recover
|
||||
plaintext after repeated timing measurements under some conditions.
|
||||
Reported and fix suggested by Luc Perneel in #3246.
|
||||
|
||||
Bugfix
|
||||
* Fix the Visual Studio Release x64 build configuration for mbedtls itself.
|
||||
Completes a previous fix in Mbed TLS 2.19 that only fixed the build for
|
||||
the example programs. Reported in #1430 and fix contributed by irwir.
|
||||
* Fix undefined behavior in X.509 certificate parsing if the
|
||||
pathLenConstraint basic constraint value is equal to INT_MAX.
|
||||
The actual effect with almost every compiler is the intended
|
||||
behavior, so this is unlikely to be exploitable anywhere. #3192
|
||||
* Fix issue with a detected HW accelerated record error not being exposed
|
||||
due to shadowed variable. Contributed by Sander Visser in #3310.
|
||||
* Avoid NULL pointer dereferencing if mbedtls_ssl_free() is called with a
|
||||
NULL pointer argument. Contributed by Sander Visser in #3312.
|
||||
* Fix potential linker errors on dual world platforms by inlining
|
||||
mbedtls_gcc_group_to_psa(). This allows the pk.c module to link separately
|
||||
from psa_crypto.c. Fixes #3300.
|
||||
* Remove dead code in X.509 certificate parsing. Contributed by irwir in
|
||||
#2855.
|
||||
* Include asn1.h in error.c. Fixes #3328 reported by David Hu.
|
||||
* Fix potential memory leaks in ecp_randomize_jac() and ecp_randomize_mxz()
|
||||
when PRNG function fails. Contributed by Jonas Lejeune in #3318.
|
||||
* Remove unused macros from MSVC projects. Reported in #3297 and fix
|
||||
submitted in #3333 by irwir.
|
||||
* Add additional bounds checks in ssl_write_client_hello() preventing
|
||||
output buffer overflow if the configuration declared a buffer that was
|
||||
too small.
|
||||
* Set _POSIX_C_SOURCE to at least 200112L in C99 code. Reported in #3420 and
|
||||
fix submitted in #3421 by Nia Alarie.
|
||||
* Fix building library/net_sockets.c and the ssl_mail_client program on
|
||||
NetBSD. Contributed by Nia Alarie in #3422.
|
||||
* Fix false positive uninitialised variable reported by cpp-check.
|
||||
Contributed by Sander Visser in #3311.
|
||||
* Update iv and len context pointers manually when reallocating buffers
|
||||
using the MBEDTLS_SSL_VARIABLE_BUFFER_LENGTH feature. This caused issues
|
||||
when receiving a connection with CID, when these fields were shifted
|
||||
in ssl_parse_record_header().
|
||||
|
||||
Changes
|
||||
* Fix warnings about signedness issues in format strings. The build is now
|
||||
clean of -Wformat-signedness warnings. Contributed by Kenneth Soerensen
|
||||
in #3153.
|
||||
* Fix minor performance issue in operations on Curve25519 caused by using a
|
||||
suboptimal modular reduction in one place. Found and fix contributed by
|
||||
Aurelien Jarno in #3209.
|
||||
* Combine identical cases in switch statements in md.c. Contributed
|
||||
by irwir in #3208.
|
||||
* Simplify a bounds check in ssl_write_certificate_request(). Contributed
|
||||
by irwir in #3150.
|
||||
* Unify the example programs termination to call mbedtls_exit() instead of
|
||||
using a return command. This has been done to enable customization of the
|
||||
behavior in bare metal environments.
|
||||
* Fix mbedtls_x509_dn_gets to escape non-ASCII characters as "?".
|
||||
Contributed by Koh M. Nakagawa in #3326.
|
||||
* Use FindPython3 when cmake version >= 3.15.0
|
||||
* Abort the ClientHello writing function as soon as some extension doesn't
|
||||
fit into the record buffer. Previously, such extensions were silently
|
||||
dropped. As a consequence, the TLS handshake now fails when the output
|
||||
buffer is not large enough to hold the ClientHello.
|
||||
* The unit tests now rely on header files in tests/include/test and source
|
||||
files in tests/src. When building with make or cmake, the files in
|
||||
tests/src are compiled and the resulting object linked into each test
|
||||
executable.
|
||||
* The ECP module, enabled by `MBEDTLS_ECP_C`, now depends on
|
||||
`MBEDTLS_CTR_DRBG_C` or `MBEDTLS_HMAC_DRBG_C` for some side-channel
|
||||
coutermeasures. If side channels are not a concern, this dependency can
|
||||
be avoided by enabling the new option `MBEDTLS_ECP_NO_INTERNAL_RNG`.
|
||||
* Align MSVC error flag with GCC and Clang. Contributed by Carlos Gomes
|
||||
Martinho. #3147
|
||||
* Remove superfluous assignment in mbedtls_ssl_parse_certificate(). Reported
|
||||
in #3182 and fix submitted by irwir. #3217
|
||||
* Fix typo in XTS tests. Reported and fix submitted by Kxuan. #3319
