We always try to keep on top of security upgrades. This build upgrades the OpenSSL library to the latest version.
To be geeky about it this build, (1) Fixed a problem with verifying a certificate chain when using the X509_V_FLAG_X509_STRICT flag (CVE-2021-3450) and (2) Fixed an issue where an OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client (CVE-2021-3449).
The latest release version is now WebCrossing 6.4 6a197da 2021-05-10.
