+Subject: [PATCH 1/2] 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
