Title:
hud-service crashed with g-assert-if-reached in GMenu call from
qtgmenu::QtGMenuModel::CreateChild()
Status in “hud” package in Ubuntu:
Fix Released
Status in “hud” source package in Trusty:
Fix Released
Bug description:
[Impact]
* Unknown GTK application causes HUD service to crash by sending
invalid menu updates via GMenu.
[Test Case]
* Not reproducable so far.
[Regression Potential]
* Worst case is that somehow HUD doesn't work on the desktop and
phone.
* There are, obviously, extensive unit and functional tests to verify
this doesn't happen.
[Other Info]
* The patch will report the offending application to
errors.ubuntu.com with all available debugging information.
* The indexes are now range checked before processing. As soon as a
window sends any invalid message it is blocked.
* Further hardening around the memory management in QtGMenu has been
carried out.
* The change is not as large as it at first appears. The majority of
the diff is simply replacing Type* with QSharedPointer<Type>. The rest
is the extra code for reporting the recoverable problem.
