+Subject: [PATCH] Don't crash on broken GIF images
+
+Broken GIF images could set invalid width and height
+values inside the image, leading to Qt creating a null
+QImage for it. In that case we need to abort decoding
+the image and return an error.
+
+Initial patch by Rich Moore.
+
+Backport of Id82a4036f478bd6e49c402d6598f57e7e5bb5e1e from Qt 5
+
+Task-number: QTBUG-38367
+Change-Id: I0680740018aaa8356d267b7af3f01fac3697312a
+Security-advisory: CVE-2014-0190
