Security
* Limit the size of calculations performed by mbedtls_mpi_exp_mod to
MBEDTLS_MPI_MAX_SIZE to prevent a potential denial of service when
generating Diffie-Hellman key pairs. Credit to OSS-Fuzz.

Security
* A failure of the random generator was ignored in mbedtls_mpi_fill_random(),
which is how most uses of randomization in asymmetric cryptography
(including key generation, intermediate value randomization and blinding)
are implemented. This could cause failures or the silent use of non-random
values. A random generator can fail if it needs reseeding and cannot not
obtain entropy, or due to an internal failure (which, for Mbed TLS's own
CTR_DRBG or HMAC_DRBG, can only happen due to a misconfiguration).

ChangeLog.d/x509-add-tag-check-to-algorithm-params Normal file
View File

@ -0,0 +1,11 @@
Security
* Fix a compliance issue whereby we were not checking the tag on the
algorithm parameters (only the size) when comparing the signature in the
description part of the cert to the real signature. This meant that a
NULL algorithm parameters entry would look identical to an array of REAL
(size zero) to the library and thus the certificate would be considered
valid. However, if the parameters do not match in *any* way then the
certificate should be considered invalid, and indeed OpenSSL marks these
certs as invalid when mbedtls did not.
Many thanks to guidovranken who found this issue via differential fuzzing
and reported it in #3629.

Security
* Zeroising of local buffers and variables which are used for calculations
in mbedtls_pkcs5_pbkdf2_hmac(), mbedtls_internal_sha*_process(),
mbedtls_internal_md*_process() and mbedtls_internal_ripemd160_process()
functions to erase sensitive data from memory. Reported by
Johan Malmgren and Johan Uppman Bruce from Sectra.
