Viscosity version 1.10.2 is now available for both macOS and Windows! This update introduces Dark Mode support for the Windows version, a security-related OpenSSL update for both macOS and Windows versions, along with several small bug fixes and enhancements.
The updated version of OpenSSL addresses a potential security issue with OpenSSL's certificate parsing that could result in a denial-of-service attack. This does not affect the security of OpenVPN connections. However, it could potentially allow a malicious server or man-in-the-middle attacker to stall a VPN connection attempt with an infinite loop, resulting in high CPU usage until the connection attempt is disconnected.
The Windows version also introduces preliminary Dark Mode support. If Windows is set to use Dark Mode, Viscosity will now automatically render its interface using the appropriate dark theme colors. This is still a work in progress, however Dark Mode fans should be less blinded when opening Viscosity's interface with this update.
The macOS version also fixes a number of small IPv6 related issues, including not correctly displaying the IPv6 address assigned to a VPN connection in the menu or Details window.
