From URL: 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. Please stabilize 2.26.0.
