+Subject: [PATCH] flacparse: Avoid integer overflow in available data check for
+ image tags
+
+If the image length as stored in the file is some bogus integer then
+adding it to the current byte readers position can overflow and wrongly
+have the check for enough available data succeed.
+
+This then later can cause NULL pointer dereferences or out of bounds
+reads/writes when actually reading the image data.
+
+Fixes ZDI-CAN-20775
+Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/2661
+
+Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4894>
