TightVNC is a free and Open Source remote desktop software that lets you access and control a computer over the network. With its intuitive interface, you can interact with the remote screen as if you were sitting in front of it. You can open files, launch applications, and perform other actions on the remote desktop almost as if you were physically there.

TightVNC is:

  • Free, GPL-licensed, with full source code available;
  • Useful in remote administration, remote customer support, education, and for many other purposes;
  • Cross-platform, available for Windows and Unix, compatible with other VNC software;
  • Well maintained and being actively developed.

This version includes both the VNC viewer and server.

What's New

  • Server for Windows: Improved security of communication between the server and its control application by generating unpredictable names for internal communication channels.
  • Server for Windows: Added validation of values returned by system functions and additional checks of the internal server state, preventing potential crashes and hangs during screen capture, cursor processing, and clipboard operations (bugs #1660, #1661, #1662, #1663, and #1665).
  • Server for Windows: Improved DLL loading security by allowing screen hook libraries to be loaded only from the TightVNC installation directory or the Windows system directory.
  • Viewer for Windows: Fixed out-of-bounds memory access that could cause a garbled display or a crash when processing invalid ZRLE-encoded screen data (bug #1657).
