- Update to 2.28.5:
Features
* The documentation of mbedtls_ecp_group now describes the optimized
representation of A for some curves. Fixes gh#Mbed-TLS/mbedtls#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 gh#Mbed-TLS/mbedtls#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 gh#Mbed-TLS/mbedtls#7873,
gh#Mbed-TLS/mbedtls#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
gh#Mbed-TLS/mbedtls#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.
