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:

c2i_ASN1_BIT_STRING takes length as a long but uses it as an int. Check bounds before doing so. Previously, excessively large inputs to the function could write a single byte outside the target buffer. (This is unreachable as asn1_ex_c2i already uses int for the length.)

OpenSSL 1.1.0 made SSL_CTX and SSL structs opaque and introduced a new API to set the minimum and maximum protocol version for SSL_CTX with TLS_method(). Add getters to introspect the configured versions: int SSL_CTX_get_min_proto_version(SSL_CTX *ctx); int SSL_CTX_get_max_proto_version(SSL_CTX *ctx); int SSL_get_min_proto_version(SSL *ssl); int SSL_get_max_proto_version(SSL *ssl); NOTE: The getters do not resolv the version in case when the minimum or maxium version are configured as '0' (meaning auto-select lowest and highst version number).

If the result of a SSL_{CTX_,}set_{min,max}_proto_version() call leaves the min and max version identical, and support for that version is compiled out of the library, return an error. Such an object has no hope of successfully completing a handshake, and this error may be easier to decipher than the resulting handshake failure. Reviewed-by:

If an alert gets sent and then we close the connection immediately with data still in the input buffer then a TCP-RST gets sent. Some OSs immediately abandon data in their input buffer if a TCP-RST is received - meaning the alert data itself gets ditched. Sending a TCP-FIN before the TCP-RST seems to avoid this. This was causing test failures in MSYS2 builds. Reviewed-by:
