asn1_item_embed_free() will try unlocking and fail in this case, and since the new item was just allocated on the heap, free it directly with OPENSSL_free() instead. Reviewed-by:

The previous change with this intention didn't quite do it. An embedded item must not be freed itself, but might potentially contain non-embedded elements, which must be freed. So instead of calling ASN1_item_ex_free(), where we can't pass the embed flag, we call asn1_item_embed_free() directly. This changes asn1_item_embed_free() from being a static function to being a private non-static function. Reviewed-by:

The lhash expand() function can fail if realloc fails. The previous implementation made changes to the structure and then attempted to do a realloc. If the realloc failed then it attempted to undo the changes it had just made. Unfortunately changes to lh->p were not undone correctly, ultimately causing subsequent expand() calls to increment num_nodes to a value higher than num_alloc_nodes, which can cause out-of-bounds reads/ writes. This is not considered a security issue because an attacker cannot cause realloc to fail. This commit moves the realloc call to near the beginning of the function before any other changes are made to the lhash structure. That way if a failure occurs we can immediately fail without having to undo anything. Thanks to Pavel Kopyl (Samsung) for reporting this issue. Reviewed-by:

The function BN_security_bits() uses the values from SP800-57 to assign security bit values for different FF key sizes. However the value for 192 security bits is wrong. SP800-57 has it as 7680 but the code had it as 7690. Reviewed-by:

An instruction's QUERY function is executed at initialization, iff the required MSA level is installed. Therefore, it is sufficient to check the bits returned by the QUERY functions. The MSA level does not have to be checked at every function call. crypto/aes/asm/aes-s390x.pl: The AES key schedule must be computed if the required KM or KMC function codes are not available. Formally, the availability of a KMC function code does not imply the availability of the corresponding KM function code. Signed-off-by:

The second set of tests in that configuration uses the AES-SHA256 ciphers, which are only available for TLS 1.2. Thus, when TLS 1.2 is disabled, there are no ciphers available and the handshake fails with an internal error. Apply the same treatment as for 13-fragmentation.conf, which uses the same ciphers.

RSA_setup_blinding() calls BN_BLINDING_create_param() which later calls BN_mod_exp() as follows: BN_mod_exp(ret->A, ret->A, ret->e, ret->mod, ctx) ret->mod will have BN_FLG_CONSTTIME set, but ret->e does not. In BN_mod_exp() we only test the third param for the existence of this flag. We should test all the inputs. Thanks to Samuel Weiser (samuel.weiser@iaik.tugraz.at) for reporting this issue. This typically only happens once at key load, so this is unlikely to be exploitable in any real scenario. Reviewed-by:

Verify that the encrypt-then-mac negotiation is handled correctly. Additionally, when compiled with no-asm, this test ensures coverage for the constant-time MAC copying code in ssl3_cbc_copy_mac. The proxy-based CBC padding test covers that as well but it's nevertheless better to have an explicit handshake test for mac-then-encrypt. Reviewed-by:

This guards against the name constraints check consuming large amounts of CPU time when certificates in the presented chain contain an excessive number of names (specifically subject email names or subject alternative DNS names) and/or name constraints. Name constraints checking compares the names presented in a certificate against the name constraints included in a certificate higher up in the chain using two nested for loops. Move the name constraints check so that it happens after signature verification so peers cannot exploit this using a chain with invalid signatures. Also impose a hard limit on the number of name constraints check loop iterations to further mitigate the issue. Thanks to NCC for finding this issue. Fix written by Martin Kreichgauer. Reviewed-by:

The pub_key field for DH isn't actually used in DH_compute_key at all. (Note the peer public key is passed in as as BIGNUM.) It's mostly there so the caller may extract it from DH_generate_key. It doesn't particularly need to be present if filling in a DH from external parameters. The check in DH_set0_key conflicts with adding OpenSSL 1.1.0 to Node. Their public API is a thin wrapper over the old OpenSSL one: https://nodejs.org/api/crypto.html#crypto_class_diffiehellman They have separate setPrivateKey and setPublicKey methods, so the public key may be set last or not at all. In 1.0.2, either worked fine since operations on DH objects generally didn't use the public key. (Like with OpenSSL, Node's setPublicKey method is also largely a no-op, but so it goes.) In 1.1.0, DH_set0_key prevents create a private-key-only DH object. (cherry picked from commit d58ad9a2a287d1c0bc99ba63c997eed88cc161b5) Reviewed-by:
