Keegan Ryan (NCC Group) has demonstrated a side channel attack on an ECDSA signature operation. During signing the signer calculates: s:= k^-1 * (m + r * priv_key) mod order The addition operation above provides a sufficient signal for a flush+reload attack to derive the private key given sufficient signature operations. As a mitigation (based on a suggestion from Keegan) we add blinding to the operation so that: s := k^-1 * blind^-1 (blind * m + blind * r * priv_key) mod order Since this attack is a localhost side channel only no CVE is assigned.

When signing or verifying a file using pkeyutl the input is supposed to be a hash. Some algorithms sanity check the length of the input, while others don't and silently truncate. To avoid accidents we check that the length of the input looks sane. Reviewed-by:

Because TLS 1.3 sends more non-application data records some clients run into problems because they don't expect SSL_read() to return and set SSL_ERROR_WANT_READ after processing it. This can cause problems for clients that use blocking I/O and use select() to see if data is available. It can be cleared using SSL_CTX_clear_mode().

* EC_POINT_mul is now responsible for constant time point multiplication (for single fixed or variable point multiplication, when the scalar is in the range [0,group_order), so we need to strip the nonce padding from ECDSA. * Entry added to CHANGES * Updated EC_POINT_mul documentation - Integrate existing EC_POINT_mul and EC_POINTs_mul entries in the manpage to reflect the shift in constant-time expectations when performing a single fixed or variable point multiplication; - Add documentation to ec_method_st to reflect the updated "contract" between callers and implementations of ec_method_st.mul.

Where a CMS detached signature is used with text content the text goes through a canonicalisation process first prior to signing or verifying a signature. This process strips trailing space at the end of lines, converts line terminators to CRLF and removes additional trailing line terminators at the end of a file. A bug in the canonicalisation process meant that some characters, such as form-feed, were incorrectly treated as whitespace and removed. This is contrary to the specification (RFC5485). This fix could mean that detached text data signed with an earlier version of OpenSSL 1.1.0 may fail to verify using the fixed version, or text data signed with a fixed OpenSSL may fail to verify with an earlier version of OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data and use the "-binary" flag (for the "cms" command line application) or set the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).

With "-multi" the OCSP responder forks multiple child processes, and respawns them as needed. This can be used as a long-running service, not just a demo program. Therefore the index file is automatically re-read when changed. The responder also now optionally times out client requests. Reviewed-by:
