In OpenSSL pre 1.1.0, 'openssl x509 -CAkeyformat engine' was possible and supported. In 1.1.0, a small typo ('F' instead of 'f') removed that possibility. This restores the pre 1.1.0 behavior. Fixes #4366 Reviewed-by:

information about the length of the scalar used in ECDSA operations from a large number (2^32) of signatures. This doesn't rate as a CVE because: * For the non-constant time code, there are easier ways to extract more information. * For the constant time code, it requires a significant number of signatures to leak a small amount of information.

The eventfd syscall is deprecated and is not available on aarch64, causing build to fail: engines/e_afalg.c: In function 'eventfd': engines/e_afalg.c:108:20: error: '__NR_eventfd' undeclared (first use in this function) return syscall(__NR_eventfd, n); ^ Instead, switch to the newer eventfd2 syscall, which is supposed to be supported by all architectures. This kind of issues would be avoided by simply using the eventfd(2) wrapper from the libc, but there must be subtle reasons not to... Tested on a aarch64 system running OpenSUSE Leap 42.1 (gcc118 from https://cfarm.tetaneutral.net/machines/list/ ) and also cross-compiling for aarch64 with LEDE (kernel 4.9).

The functions strcasecmp() and strncasecmp() will use locale specific rules when performing comparison. This could cause some problems in certain locales. For example in the Turkish locale an 'I' character is not the uppercase version of 'i'. However IA5 strings should not use locale specific rules, i.e. for an IA5 string 'I' is uppercase 'i' even if using the Turkish locale. This fixes a bug in name constraints checking reported by Thomas Pornin (NCCGroup). This is not considered a security issue because it would require both a Turkish locale (or other locale with similar issues) and malfeasance by a trusted name-constrained CA for a certificate to pass name constraints in error. The constraints also have to be for excluded sub-trees which are extremely rare. Failure to match permitted subtrees is a bug, not a vulnerability. Reviewed-by:

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 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.

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.
