Too many KeyUpdate message could be inicative of a problem (e.g. an infinite KeyUpdate loop if the peer always responds to a KeyUpdate message with an "update_requested" KeyUpdate response), or (conceivably) an attack. Either way we limit the number of KeyUpdate messages we are prepared to handle. Reviewed-by:

For client auth call tls_choose_sigalg to select the certificate and signature algorithm. Use the selected algorithm in tls_construct_cert_verify. Remove obsolete tls12_get_sigandhash. Reviewed-by:

Select appropriate signature algorithm and certificate for client authentication using tls_choose_sigalg. A lot of selection logic is very similar except not finding a certificate is not a fatal error: we just do not present a certificate. For TLS 1.2 and earlier we only check the current certificate is suitable (for compatibility with previous logic) for TLS 1.3 (where there are no compatibility issues) we support multiple client certificates for different algorithms.

The intent seems to be that the WIN32 symbol is for things that are a direct byproduct of being a windows-variant configuration and should be used for feature en/disablement on windows systems. Use of the _WIN32 symbol is more widespread, being used to implement platform portability of more generic code. We do define WIN32 in some situations in e_os.h, but that is not included universally.

Following on from CVE-2017-3733, this removes the OPENSSL_assert() check that failed and replaces it with a soft assert, and an explicit check of value with an error return if it fails. Reviewed-by: -

In 1.1.0 changing the ciphersuite during a renegotiation can result in a crash leading to a DoS attack. In master this does not occur with TLS (instead you get an internal error, which is still wrong but not a security issue) - but the problem still exists in the DTLS code. The problem is caused by changing the flag indicating whether to use ETM or not immediately on negotiation of ETM, rather than at CCS. Therefore, during a renegotiation, if the ETM state is changing (usually due to a change of ciphersuite), then an error/crash will occur. Due to the fact that there are separate CCS messages for read and write we actually now need two flags to determine whether to use ETM or not. CVE-2017-3733 Reviewed-by: -
