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:

XN_FLAG_COMPAT has a unique property, its zero for value. This means it needs special treatment; if it has been set (which can only be determined indirectly) and set alone (*), no other flags should be set. (*) if any other nameopt flag has been set by the user, compatibility mode is blown away. Reviewed-by:

OpenSSL 1.1.0 made the X509_LOOKUP_METHOD structure opaque, so applications that were previously able to define a custom lookup method are not able to be ported. This commit adds getters and setters for each of the current fields of X509_LOOKUP_METHOD, along with getters and setters on several associated opaque types (such as X509_LOOKUP and X509_OBJECT).

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:

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.
