The man pages say that BIGNUM arithmetic operations fail with a 0 return. However some functions were returning -1 on error. In master and 1.1.0 they already return 0, so this brings 1.0.2 in line. Reviewed-by:

information about the length of a value used in DSA operations from a large number 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.

1ce95f19 was incomplete and did not handle the case when SSL_set_SSL_CTX was called from the cert_cb callback rather than the SNI callback. The consequence is any server using OpenSSL 1.0.2 and the cert_cb callback for SNI only ever signs a weak digest, SHA-1, even when connecting to clients which use secure ones. Fix this and add regression tests for both this and the original issue. Fixes #4554. Reviewed-by:

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:

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 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 combine 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:

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:
