#13901 fixed rdesktop-vrdp segmentation fault when attaching remote USB devices Carl Lo
Description

I tried to access the Win7 guest on CentOS 5 host from another machine running CentOS 5 using "rdesktop-vrdp -r usb". VirtualBox 4.3.22 and the extension Pack was installed on host and the VRDP client.

USB filter was defined for a USB HID TouchPad that I want to use when I access the Win7 from the VRDP client. I have tested the TouchPad on the VM host and the Win7 guest can use it without any problem.

Then I access the Win7 guest via VRDP. Everything still fine. Then I plugged the TouchPad to the VRDP client machine, the rdesktop-vrdp crash with "segmentation fault" returned.

On the host side, I got a pop-up dialog showing "NS_ERROR_FAILURE ... Failed to create a proxy device for the USB device..."

Following is the log from VBox.log on the host:

VRDP: New connection:

I then fallback to use version 4.2.18, and finally can use the USB redirect function after searched for many articles/blogs/form posts. But required some USB device operations manually. As it was another issue, maybe I will discuss about it in forum or create another ticket.

Really hope the VBox experts to help, so that I can use the powerful VRDP USB redirect function.

#6554 obsolete rdesktop-vrdp segfaults in XPutImage on Debian Squeeze/i386 Maximilian Gass
Description

I created a Debian package for rdesktop-vrdp from VirtualBox 3.1.6. It works fine on a Debian Squeeze amd64 workstation, but segfaults after login on a Debian Squeeze i386 live system I am creating.

I have localized the problem in ui_desktop_restore in xwin.c. The call to XCreateImage returns NULL sometimes and then XPutImage triggers a segmentation fault.
