TlsGetValue clears the last error even on success, so that callers may distinguish it successfully returning NULL or failing. This error-mangling behavior interferes with the caller's use of GetLastError. In particular SSL_get_error queries the error queue to determine whether the caller should look at the OS's errors. To avoid destroying state, save and restore the Windows error. Fixes #6299. Reviewed-by:

Don't apply DNS name constraints to the subject CN when there's a least one DNS-ID subjectAlternativeName. Don't apply DNS name constraints to subject CN's that are sufficiently unlike DNS names. Checked name must have at least two labels, with all labels non-empty, no trailing '.' and all hyphens must be internal in each label. In addition to the usual LDH characters, we also allow "_", since some sites use these for hostnames despite all the standards. Reviewed-by:

A previous change of this function introduced a fragility when the destination happens to be the same as the source. Such alias isn't recommended, but could still happen, for example in this kind of code: X509_NAME *subject = X509_get_issuer_name(x); /* ... some code passes ... */ X509_set_issuer_name(x, subject); Fixes #4710 Reviewed-by:

Experiments have shown that the lookup table used by BN_GF2m_mod_arr introduces sufficient timing signal to recover the private key for an attacker with access to cache timing information on the victim's host. This only affects binary curves (which are less frequently used). No CVE is considered necessary for this issue. The fix is to replace the lookup table with an on-the-fly calculation of the value from the table instead, which can be performed in constant time. Thanks to Youngjoo Shin for reporting this issue.

In DTLS if we have buffered a fragment for a zero length message (e.g. ServerHelloDone) then, when we unbuffered the fragment, we were attempting to memcpy the contents of the fragment which is zero length and a NULL pointer.

Commit d316cdcf introduced some extra checks into the session-cache update procedure, intended to prevent the caching of sessions whose resumption would lead to a handshake failure, since if the server is authenticating the client, there needs to be an application-set "session id context" to match up to the authentication context. While that change is effective for its stated purpose, there was also some collatoral damage introduced along with the fix -- clients that set SSL_VERIFY_PEER are not expected to set an sid_ctx, and so their usage of session caching was erroneously denied. Fix the scope of the original commit by limiting it to only acting when the SSL is a server SSL. Reviewed-by:
