WinVNC Version History Version 3.3.3 (VNC Version 3.3.3, revision 9) Changes from Version 3.3.3 Revision 8: Fixed handling of empty (match all) AuthHosts filters. WinVNC.log will now be moved to WinVNC.log.bak when WinVNC runs. Version 3.3.3 (VNC Version 3.3.3, revision 8) Changes from Version 3.3.3 Revision 7: -=- Bug Fixes to WinVNC: Fixed clipboard handling. Fixed AddClient semantics in vncServer to avoid a socket leak. Fixed AuthHosts dialog display. Now flashes titlebar/tray button if not foreground window. Fixed AuthHosts string parsing. Filters such as 10.0.0.1 no longer match 10.0.0.10. QuerySetting didn't work correctly if the AuthHosts string was empty. Fixed. Closing the screen-saver now works, so it's back in there. Changed the shutdown-dialog behaviour. It now only operates in application mode. -=- Bug Fixes to VNCHooks: Added HooksType() function to VNChooks so that the library may be replaced with a reliable hooking version easily. VNCHooks DLL did not remove properties from windows correctly when UnsetHooks() was called. Fixed. -=- Minor Fixes Implemented the wallpaper-culling feature during remote connections. Added automatic culling of "idle" connections, if required, via the IdleTimeout setting. An idle connection is one in which the client has sent no data for a fixed period, whether the data be an update request, input events, or clipboard data. Only incoming connections are now checked for validity. Outgoing (Add New Client) or CORBA-initiated connections are not checked via AuthHosts. Version 3.3.3 (VNC Version 3.3.3, revision 7) Changes from Version 3.3.3 Revision 6: WinVNC did not correctly handle Winsock1.1, causing all client connections to be erroneously dropped by the anti-DoS code. Now fixed. Version 3.3.3 (VNC Version 3.3.3, revision 6) Changes from Version 3.3.3 Revision 4: The anti denial-of-service blacklist code was very buggy. It's now fixed. An serious potential deadlock condition in the negotiation phase of new clients has been fixed. The problem was incredibly rare on uniprocessors but much more noticable on multiprocessors, unsurprisingly. Pointer is now rendered slightly better. Version 3.3.3 (VNC Version 3.3.3, revision 4) Changes from Version 3.3.3 Revision 3: Implemented some simple Denial-of-Service protection. After five consecutive failed connection attempts from a client, that client is "blacklisted" for ten seconds. In addition, connections which hang before the authentication stage has completed are timed out after thirty seconds, to prevent malicious users gradually eating up socket resources. Corrected a bug initialising the back-buffer. Added hooking for dialog boxes, menus and scrollbars. Seems to fix some dialogs but not many scrollbars or menus.. Improved the GetChangesRect code with some alignment patches suggested by Will Dean. Fixed an *IDIOTIC* bug in the handling of user-specific settings. They were completely broken before. Now they should work. I'm such an idiot. Idiot idiot idiot. See MS Knowledge Base article Q168877 & Q199190. The idiot bug-fix above broke roaming profiles on NT domains! That's now fixed, too. Idiot idiot idiot. Added a dialog to query whether to accept or reject incoming connections. The dialog is currently controlled ONLY via the registry! The AuthHosts setting is now extended, while some new user-specific settings are provided so that users can tailor the query feature. Relevant keys are: - QuerySetting (DWORD) (local&global user-specific) [Least secure] 0 - Accept or Query. If AuthHosts says Reject then query, otherwise Accept. 1 - Accept or Reject. Reject if AuthHosts says so, otherwise Accept. 2 - Obey AuthHosts. Obey AuthHosts Accept, Query, Reject settings. [Default!] 3 - Query or Reject. If AuthHosts says Reject then Reject, otherwise Query. 4 - Ultimate Paranoia. If AuthHosts says Accept then Query, otherwise Reject! [Most secure] Summary: Actual Effect Setting Accept Query Reject 0 a a q 1 a a r 2 a q r 3 q q r 4 q r r - QueryTimeout (DWORD) (local&global user-specific) Number of seconds before Accept/Reject dialog should timeout and reject. - AuthHosts (SZ) (machine-local) Match terms may now start with "-", "+" or "?". "?" indicates that the connection attempt should be queried. Version 3.3.3 (VNC Version 3.3.3, revision 3) Changes from Version 3.3.3 Revision 2: Implemented Will Dean's DIBsection patch to retrive screen data. This reduces both the retrieval time & the memory usage of WinVNC but currently only works for VNC-format-compatible 16 and 32 bit displays. If your display is incompatible then WinVNC falls back to the old, slow, memory hungry mode. Fixed a bug in VNCHooks which cause very large updates to be spuriously created on occasion. vncKeymap now filters out the three Lock keys (CapsLock, NumLock, ScrollLock), so that they can be safely used at the client side without generating random keystrokes on the server. Version 3.3.3 (VNC Version 3.3.3, revision 2) Changes from Version 3.3.3 Revision 1: Added the new "Disable Local Keyboard & Pointer" option to the Properties dialog. This features currently allows the keyboard & pointer of the sever machine to be disabled while a remote connection is in progress. The feature only works under Windows NT at present. NB:This is a BETA feature, with a known limitation - if the setting is changed then all clients must disconnect and reconnect to achieve the desired effect. The -connect command-line option has been added, allowing new outgoing connections to be made using a script or an icon. The Add New Client and -connect options now make shared outgoing connections, since this is usually preferable to unshared outgoing connections. Improved the way preferences are loaded, reducing the number of times the client will be disconnected when settings are loaded & saved. Version 3.3.3 (VNC Version 3.3.3, revision 1) Release version, patched for HTML bug below. [The initial 3.3.3 release featured a bug in the rendering of HTML for the Java-based viewer. 3.3.3 was quickly withdrawn and 3.3.3R1 is now the base Version 3.3.3 release.] -=- NEW FEATURES: REGISTRY SETTINGS ARE NOW LOADED CORRECTLY FROM THE CURRENT_USER REGISTRY HIVE! When running as a service under Windows NT, WinVNC was unable to correctly load settings stored in the current user's HKEY_CURRENT_USER hive. As a workaround for this, a special helper-hook is installed when the service itself is installed. The helper-hook runs when a user logs in and passes enough information to the WinVNC service for it to locate their preferences correctly. If the helper hook fails to install or isn't run for some reason, then WinVNC will continue to operate based on ALL the WinVNC HKEY_LOCAL_MACHINE settings. A new command-line option, -defaultsettings, has been added, which will cause the running WinVNC server to show a Default Properties dialog, through which the default local properties can be editted. (While the dialog is displayed, the properties used will be the default ones. When it dissappears, WinVNC reverts to the user's settings.) Nagle's algorithm is now disabled on all WinVNC connections, decreasing latency considerably. Timestamp information is now added in the debug log output. Limited client IP-address based filtering of connections is now supported. The new Machine-Local registry setting "AuthHosts" may be specified, and should be of type "string". Match terms look like: +<ip-address-template> -<ip-address-tamplate> where ip-address-template is the leftmost bytes of the stringified IP-address, e.g. 158.97 would match both 158.97.54.1 and 15
