Category: Windows version Group: 1.2.X Status: Open Resolution: None Priority: 5 Private: No Submitted By: William Hooper (wahooper) Assigned to: Peter Åstrand (astrand) Summary: WinVNC Crash on WinXP and Internet Explorer Initial Comment: I've seen this in both the beta 1.1.90 version and the release 1.2.0 version. When I run TigerVNC (in either service mode or user mode) on Windows XP SP3, connecting with multiple VNC clients. I can consistently repeat the crash by opening up Internet Explorer 8 and selecting the address bar to enter a URL. Here is the only crash info Windows gives: szAppName : winvnc4.exe szAppVer : 1.2.0.0 szModName : unknown szModVer : 0.0.0.0 offset : 00000000 ---------------------------------------------------------------------- Comment By: Ashley Gittins (agittins) Date: 2012-08-31 19:22 Message: Ok, I changed to the Cirrus driver for my XP guest and still had the same problems so it doesn't appear to be related to the driver in my case. I downgraded to 1.1.0 and all the problems went away. I don't have much else to contribute except to say that I can reproduce the OP's problem using another app, with 100% repeatability, upon a specific application receiving mouseover on its edit boxes. ---------------------------------------------------------------------- Comment By: Ashley Gittins (agittins) Date: 2012-08-31 00:12 Message: I'm seeing similar problems here. I have a 32bit WinXP SP3 machine running under QEMU, using the standard VGA driver. I have a horrid industry-specific application that causes the crash in winvnc4.exe as soon as any of its editboxes gets/triggers a mouseover (ie, as soon as my mouse cursor enters the area of an edit box, and before the cursor changes to a carat pointer, winvnc4.exe crashes). I just tried setting vnc to poll windows instead of using hooks but it still crashes. Interestingly it doesn't matter if it's the vnc client or the server that's sending the mousemove, as long as there is an active vnc session the vnc service will crash on entering the editbox. This started happening when I updated to TigerVNC 1.2.0 today, previously I think I had been running 1.0.1 but tbh I didn't check before updating. No further information on the crash was evident in the application event log, but there were a few log entries thrown while winvnc4.exe started up (I am running it as a service): CleanDesktop, failed to get/set Active Desktop options:-2147024809 SDisplay, hook subsystem failed to initialise WMHooks, failed to initialise hooks. After changing to polling (instead of using vnc hooks) the error above about wmhooks no longer appeared, but the crashes persist. I am currently using the straight VGA driver with qemu but I just noticed windows has exclamation-marked it in the drivers, will see if sorting that out helps... I can attach a memory dump if it might help but I can't do much else debugging wise as I don't have the time and will probably just downgrade if I can't get it sorted. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1126848&aid=3513768&group_id=254363 ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
