Thank you for the investigation. I agree that the code base underwent a
major refactoring and probably CVE-2017-6504 does not apply to Wheezy.
However I think Wheezy is still affected by CVE-2017-6504 which is
basically the absence of an escape function to sanitize several strings
and values. For instance this can be seen if you compare the following
lines from propertieswidget.cpp and peerlistwidget.cpp from before the
fix and in Wheezy:





m_listModel->setData(m_listModel->index(row, PeerListDelegate::CLIENT),


listModel->setData(listModel->index(row, PeerListDelegate::CLIENT),

Different code but strings are not escaped.
