mbed TLS ChangeLog (Sorted per branch, date)
|
||||
|
||||
= mbed TLS 2.26.0 branch released 2021-03-08
|
||||
|
||||
API changes
|
||||
* Renamed the PSA Crypto API output buffer size macros to bring them in line
|
||||
with version 1.0.0 of the specification.
|
||||
* The API glue function mbedtls_ecc_group_of_psa() now takes the curve size
|
||||
in bits rather than bytes, with an additional flag to indicate if the
|
||||
size may have been rounded up to a whole number of bytes.
|
||||
* Renamed the PSA Crypto API AEAD tag length macros to bring them in line
|
||||
with version 1.0.0 of the specification.
|
||||
|
||||
Default behavior changes
|
||||
* In mbedtls_rsa_context objects, the ver field was formerly documented
|
||||
as always 0. It is now reserved for internal purposes and may take
|
||||
different values.
|
||||
|
||||
New deprecations
|
||||
* PSA_KEY_EXPORT_MAX_SIZE, PSA_HASH_SIZE, PSA_MAC_FINAL_SIZE,
|
||||
PSA_BLOCK_CIPHER_BLOCK_SIZE, PSA_MAX_BLOCK_CIPHER_BLOCK_SIZE and
|
||||
PSA_ALG_TLS12_PSK_TO_MS_MAX_PSK_LEN have been renamed, and the old names
|
||||
deprecated.
|
||||
* PSA_ALG_AEAD_WITH_DEFAULT_TAG_LENGTH and PSA_ALG_AEAD_WITH_TAG_LENGTH
|
||||
have been renamed, and the old names deprecated.
|
||||
|
||||
Features
|
||||
* The PSA crypto subsystem can now use HMAC_DRBG instead of CTR_DRBG.
|
||||
CTR_DRBG is used by default if it is available, but you can override
|
||||
this choice by setting MBEDTLS_PSA_HMAC_DRBG_MD_TYPE at compile time.
|
||||
Fix #3354.
|
||||
* Automatic fallback to a software implementation of ECP when
|
||||
MBEDTLS_ECP_xxx_ALT accelerator hooks are in use can now be turned off
|
||||
through setting the new configuration flag MBEDTLS_ECP_NO_FALLBACK.
|
||||
* The PSA crypto subsystem can now be configured to use less static RAM by
|
||||
tweaking the setting for the maximum amount of keys simultaneously in RAM.
|
||||
MBEDTLS_PSA_KEY_SLOT_COUNT sets the maximum number of volatile keys that
|
||||
can exist simultaneously. It has a sensible default if not overridden.
|
||||
* Partial implementation of the PSA crypto driver interface: Mbed TLS can
|
||||
now use an external random generator instead of the library's own
|
||||
entropy collection and DRBG code. Enable MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG
|
||||
and see the documentation of mbedtls_psa_external_get_random() for details.
|
||||
* Applications using both mbedtls_xxx and psa_xxx functions (for example,
|
||||
applications using TLS and MBEDTLS_USE_PSA_CRYPTO) can now use the PSA
|
||||
random generator with mbedtls_xxx functions. See the documentation of
|
||||
mbedtls_psa_get_random() for details.
|
||||
* In the PSA API, the policy for a MAC or AEAD algorithm can specify a
|
||||
minimum MAC or tag length thanks to the new wildcards
|
||||
PSA_ALG_AT_LEAST_THIS_LENGTH_MAC and
|
||||
PSA_ALG_AEAD_WITH_AT_LEAST_THIS_LENGTH_TAG.
|
||||
|
||||
Security
|
||||
* Fix a security reduction in CTR_DRBG when the initial seeding obtained a
|
||||
nonce from entropy. Applications were affected if they called
|
||||
mbedtls_ctr_drbg_set_nonce_len(), if they called
|
||||
mbedtls_ctr_drbg_set_entropy_len() with a size that was 3/2 times the key
|
||||
length, or when the entropy module uses SHA-256 and CTR_DRBG uses AES-256.
|
||||
In such cases, a random nonce was necessary to achieve the advertised
|
||||
security strength, but the code incorrectly used a constant instead of
|
||||
entropy from the nonce.
|
||||
Found by John Stroebel in #3819 and fixed in #3973.
|
||||
* Fix a buffer overflow in mbedtls_mpi_sub_abs() when calculating
|
||||
|A| - |B| where |B| is larger than |A| and has more limbs (so the
|
||||
function should return MBEDTLS_ERR_MPI_NEGATIVE_VALUE). Only
|
||||
applications calling mbedtls_mpi_sub_abs() directly are affected:
|
||||
all calls inside the library were safe since this function is
|
||||
only called with |A| >= |B|. Reported by Guido Vranken in #4042.
|
||||
* Fix an errorneous estimation for an internal buffer in
|
||||
mbedtls_pk_write_key_pem(). If MBEDTLS_MPI_MAX_SIZE is set to an odd
|
||||
value the function might fail to write a private RSA keys of the largest
|
||||
supported size.
|
||||
Found by Daniel Otte, reported in #4093 and fixed in #4094.
|
||||
* Fix a stack buffer overflow with mbedtls_net_poll() and
|
||||
mbedtls_net_recv_timeout() when given a file descriptor that is
|
||||
beyond FD_SETSIZE. Reported by FigBug in #4169.
|
||||
* Guard against strong local side channel attack against base64 tables by
|
||||
making access aceess to them use constant flow code.
|
||||
|
||||
Bugfix
|
||||
* Fix use-after-scope error in programs/ssl/ssl_client2.c and ssl_server2.c
|
||||
* Fix memory leak that occured when calling psa_close_key() on a
|
||||
wrapped key with MBEDTLS_PSA_CRYPTO_SE_C defined.
|
||||
* Fix an incorrect error code if an RSA private operation glitched.
|
||||
* Fix a memory leak in an error case in psa_generate_derived_key_internal().
|
||||
* Fix a resource leak in CTR_DRBG and HMAC_DRBG when MBEDTLS_THREADING_C
|
||||
is enabled, on platforms where initializing a mutex allocates resources.
|
||||
This was a regression introduced in the previous release. Reported in
|
||||
#4017, #4045 and #4071.
|
||||
* Ensure that calling mbedtls_rsa_free() or mbedtls_entropy_free()
|
||||
twice is safe. This happens for RSA when some Mbed TLS library functions
|
||||
fail. Such a double-free was not safe when MBEDTLS_THREADING_C was
|
||||
enabled on platforms where freeing a mutex twice is not safe.
|
||||
* Fix a resource leak in a bad-arguments case of mbedtls_rsa_gen_key()
|
||||
when MBEDTLS_THREADING_C is enabled on platforms where initializing
|
||||
a mutex allocates resources.
|
||||
* Fixes a bug where, if the library was configured to include support for
|
||||
both the old SE interface and the new PSA driver interface, external keys were
|
||||
not loaded from storage. This was fixed by #3996.
|
||||
* This change makes 'mbedtls_x509write_crt_set_basic_constraints'
|
||||
consistent with RFC 5280 4.2.1.9 which says: "Conforming CAs MUST
|
||||
include this extension in all CA certificates that contain public keys
|
||||
used to validate digital signatures on certificates and MUST mark the
|
||||
extension as critical in such certificates." Previous to this change,
|
||||
the extension was always marked as non-critical. This was fixed by
|
||||
#3698.
|
||||
|
||||
Changes
|
||||
* A new library C file psa_crypto_client.c has been created to contain
|
||||
the PSA code needed by a PSA crypto client when the PSA crypto
|
||||
implementation is not included into the library.
|
||||
* On recent enough versions of FreeBSD and DragonFlyBSD, the entropy module
|
||||
now uses the getrandom syscall instead of reading from /dev/urandom.
