This patch is from upstream and should be fixed included in the next release
From e96fc4fdd525fa0ede28074a7e2b1caf94b58b0d Mon Sep 17 00:00:00 2001
From: Michael Adams <mdadams@ece.uvic.ca>
Date: Sat, 4 Mar 2017 14:43:24 -0800
Subject: [PATCH] Fixed bugs due to uninitialized data in the JP2 decoder.
Also, added some comments marking I/O stream interfaces that probably need to
be changed (in the long term) to fix integer overflow problems.
