UltraVNC (using SecureVNC) application error popups

Post by Raccoon »

Hello,

I am running UltraVNC server on Windows 7 Embedded x64 where we are using a custom OS shell (instead of explorer.exe). The server service is not configured to automatically start up, instead it gets launched by another application on demand. At one point we started using the SecureVNC plugin, but when doing so we would occasionally experience application error popups from winvnc.exe of the type "The instruction at 0x3f6679f9 referenced memory at 0x02da80d0. The memory could not be read." when connecting.

After debugging with the source code, it seems like the root cause is that the IconFaultCounter integer variable keeps getting incremented (even with "Disable Tray Icon" is set to true), causing the vncMenu thread to be killed (with a logging message of "user name has changed"). Normally this has not caused any issues to the users before SecureVNC, but it seems like this might interfere with the DSM plugin usage. Disabling the use of the IconFaultCounter variable in the source code appears to have fixed the issue for us. Is it possible to confirm that this is really what the bug is, and if so, could it be fixed for future versions so that a custom build from source code isn't necessary :P

Cheers!

Congratulations, a build isn't that easy.

I think there was an option to set a custom shell in UltaVnc, I need to verify it in code.
Explorer.exe is used to impersonate the desktop user, but if it isn't running we could get a NULL somewere.
Possible this is the cause behind crash.

I check it this evening.

Checking to see if there is any update ...

Is this the custom shell option you describe:

[admin]
alternate_shell=My.Alternate.Shell.exe

Thank you for the response earlier. I have tried any configuration I could find that could be relevant to your input, including the alternate_shell=My.Alternate.Shell.exe config mentioned in previous post. Behavior was apparently the same.

To add some more information regharding this, I provide logs of one run (sorry that I didn't have any at hand until now):

These logs are from simply starting the service, running idle for a few minutes, then closing the service (I had to cut truncate the log due to forum post length restriction). The version during this specific run was 1.1.9.6, and no DSM plugin was used. We have not experienced any crashes when running without the SecureVNC plugin, however what you can still see in these logs is the frequent "vncmenu.cpp : user name has changed" log entry, followed by "vncmenu.cpp : ############## Kill vncMenu thread". When adding the DSM plugin on top of this, we are experiencing the error popup.

Cheers

Re: UltraVNC (using SecureVNC) application error popups

Post by Rudi De Vos »

WHat you see is the start and stop of the menu.
The menu run as desktop user, each time a user change the menu thread is also restarted.

Desktop switch
SelectHDESK to Default (dc) from 24 = switch from default to logon desktop

Kill vncMenu thread
The menu run as the current desktop user, if a user change the menu need to re-impersonate the new desktop user.
The owner of the logon screen is the system, once a user is logged this change in the desktop user

The logging is cleaned in the later versions, also if no systray exist you now can use the hideIcon to avoid the vnc try to set the trayicon over and over. (DisableTrayIcon = 1)

If possible use the latest version, many bugs are solved and logging is better.

Hi Rudi and thank you for the reply,

Sorry for providing logs from an outdated version, I have logs from a run with 1.2.2.3 here (also with DisableTrayIcon=1).

There is no user interaction with the system (or any connections initiated) other than starting and stopping the service during the course of the logs, so there should not be any user change or desktop change. When I made a build from source code (1.2.2.3 source code) where the incremental of IconFaultCounter (vncmenu.cpp) was commented out or removed, the user change and vncmenu thread kill log messages could not be seen.

Re: UltraVNC (using SecureVNC) application error popups

Hi
After debugging with the source code, it seems like the root cause is that the IconFaultCounter integer variable keeps getting incremented (even with "Disable Tray Icon" is set to true), causing the vncMenu thread to be killed (with a logging message of "user name has changed").
Is there a way to get this problem fixed or alternatively as to have the IconFaultCounter as configurable parameter. Since we are experiencing the same problem it would be brilliant if that could get resolved.

Cheers,
Top
