In previous versions of OpenSSL, the documentation for PEM_read_* said: The callback B<must> return the number of characters in the passphrase or 0 if an error occurred. But since c82c3462 , 0 is now treated as a non-error return value. Applications that want to indicate an error need to return -1 instead. Reviewed-by:

This extends the recently added ECDSA signature blinding to blind DSA too. This is based on side channel attacks demonstrated by Keegan Ryan (NCC Group) for ECDSA which are likely to be able to be applied to DSA. Normally, as in ECDSA, during signing the signer calculates: s:= k^-1 * (m + r * priv_key) mod order In ECDSA, 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. This commit also tweaks the previous ECDSA blinding so that blinding is only removed at the last possible step. Reviewed-by:

If the remove_session_cb accesses the session's data (for instance, via SSL_SESSION_get_protocol_version), a potential use after free can occur. For this, consider the following scenario when adding a new session via SSL_CTX_add_session: - The session cache is full (SSL_CTX_sess_number(ctx) > SSL_CTX_sess_get_cache_size(ctx)) - Only the session cache has a reference to ctx->session_cache_tail (that is, ctx->session_cache_tail->references == 1) Since the cache is full, remove_session_lock is called to remove ctx->session_cache_tail from the cache. That is, it SSL_SESSION_free()s the session, which free()s the data. Afterwards, the free()d session is passed to the remove_session_cb. If the callback accesses the session's data, we have a use after free. The free before calling the callback behavior was introduced in commit e4612d02 ("Remove sessions from external cache, even if internal cache not used."). CLA: trivial Reviewed-by:

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:
