Version 1.4.8 of Viscosity for both Mac and Windows is now available! This version addresses the recent OpenSSL "Heartbleed" security vulnerability, and all users are strongly advised to update to this release as soon as possible.
The OpenSSL "Heartbleed" bug is a very serious vulnerability in versions 1.0.1 to 1.0.1f of OpenSSL. OpenSSL is OpenVPN's default library for providing encryption services and hence OpenVPN users are exposed to this flaw. While it is more difficult for an attacker to target an OpenVPN client than a server, it could still potentially allow an attacker to obtain session keys and decrypted data and so it should be treated seriously. Version 1.0.1g of OpenSSL fixes this flaw and this is the version included with Viscosity 1.4.8.
