Description

The WC_ALLOC_VAR_EX call at

wolfssl/wolfcrypt/src/random.c

Line 1738 in a4e2d85

WC_ALLOC_VAR_EX(drbg, DRBG_internal, sizeof(DRBG_internal), heap,

seems to have an invalid size specified:

    WC_ALLOC_VAR_EX(drbg, DRBG_internal, sizeof(DRBG_internal), heap,
        DYNAMIC_TYPE_TMP_BUFFER, WC_DO_NOTHING);

in an environment with WOLFSSL_SMALL_STACK defined, this macro basically results in calling:

wolfSSL_Malloc(sizeof(DRBG_internal) * sizeof(DRBG_internal));

which results in a malloc call for 16384 bytes
