Description Matt McCutchen 2013-05-15 04:27:45 UTC
Description of problem:
The viewer accepts clipboard updates from the server even when --AcceptClipboard=0 is passed on the command line.

I want to be able to copy and paste between local applications while a VNC session to an untrusted account is running without risk of the VNC session overwriting my local clipboard with harmful content without notice.  To do so, I need to configure the viewer not to accept clipboard updates.  (I have a separate script to copy data between the local and remote clipboards when I request it.)

Version-Release number of selected component (if applicable):
tigervnc-1.2.80-0.10.20130314svn5065.fc18.x86_64

How reproducible:
Always

Steps to Reproduce:
1. vncserver :2 (or some available display number)
2. vncviewer --AcceptClipboard=0 :2
3. In the VNC session, copy something to the clipboard.
4. Go to a window outside the VNC session and paste.

Actual results:
The content from the VNC session is pasted.

Expected results:
The content previously on the local clipboard, if any, is pasted.

Fix

I rebuilt the tigervnc RPMs with the attached patch and it seems to fix the problem.

It looks like the conditional on acceptClipboard was lost in the move to the "new FLTK viewer" (upstream SVN r4345).  Ideally I would take this bug upstream; we'll see if I get around to it.
