Currently SM2 shares the ameth with EC, so the current default digest algorithm returned is SHA256. This fixes the default digest algorithm of SM2 to SM3, which is the only valid digest algorithm for SM2 signature. Reviewed-by:

Some signature algorithms require special treatment for digesting, such as SM2. This patch adds the ability of handling raw input data in apps/pkeyutl other than accepting only pre-hashed input data. Beside, SM2 requries an ID string when signing or verifying a piece of data, this patch also adds the ability for apps/pkeyutil to specify that ID string. Reviewed-by:

The real cause for this change is that test/ec_internal_test.c includes ec_lcl.h, and including curve448/curve448_lcl.h from there doesn't work so well with compilers who always do inclusions relative to the C file being compiled. Reviewed-by:

Thanks to David Benjamin who reported this, performed the analysis and suggested the patch. I have incorporated some of his analysis in the comments below. This issue can cause an out-of-bounds read. It is believed that this was not reachable until the recent "fixed top" changes. Analysis has so far only identified one code path that can encounter this - although it is possible that others may be found. The one code path only impacts 1.0.2 in certain builds. The fuzzer found a path in RSA where iqmp is too large. If the input is all zeros, the RSA CRT logic will multiply a padded zero by iqmp. Two mitigating factors: - Private keys which trip this are invalid (iqmp is not reduced mod p). Only systems which take untrusted private keys care. - In OpenSSL 1.1.x, there is a check which rejects the oversize iqmp, so the bug is only reproducible in 1.0.2 so far. Fortunately, the bug appears to be relatively harmless. The consequences of bn_cmp_word's misbehavior are: - OpenSSL may crash if the buffers are page-aligned and the previous page is non-existent. - OpenSSL will incorrectly treat two BN_ULONG buffers as not equal when they are equal. - Side channel concerns. The first is indeed a concern and is a DoS bug. The second is fine in this context. bn_cmp_word and bn_cmp_part_words are used to compute abs(a0 - a1) in Karatsuba. If a0 = a1, it does not matter whether we use a0 - a1 or a1 - a0. The third would be worth thinking about, but it is overshadowed by the entire Karatsuba implementation not being constant time. Due to the difficulty of tripping this and the low impact no CVE is felt necessary for this issue. Reviewed-by:

Prior to this commit we were keeping a count of how many KeyUpdates we have processed and failing if we had had too many. This simplistic approach is not sufficient for long running connections. Since many KeyUpdates would not be a particular good DoS route anyway, the simplest solution is to simply remove the key update count. Fixes #8068 Reviewed-by:

Fixes #7950 It was reported that there might be a null pointer dereference in the implementation of the dasync_aes_128_cbc_hmac_sha1() cipher, because EVP_aes_128_cbc_hmac_sha1() can return a null pointer if AES-NI is not available. It took some analysis to find out that this is not an issue in practice, and these comments explain the reason to comfort further NPD hunters.
