 ===================================
     Library
     -------
+    - Fixed CVE-2018-11202
+
+      A malformed file could result in chunk index memory leaks. Under most
+      conditions (i.e., when the --enable-using-memchecker option is NOT
+      used), this would result in a small memory leak and and infinite loop
+      and abort when shutting down the library. The infinite loop would be
+      due to the "free list" package not being able to clear its resources
+      so the library couldn't shut down. When the "using a memory checker"
+      option is used, the free lists are disabled so there is just a memory
+      leak with no abort on library shutdown.
+
+      The chunk index resources are now correctly cleaned up when reading
+      misparsed files and valgrind confirms no memory leaks.
+
+    - Fixed an assertion in a previous fix for CVE-2016-4332
+
+      An assert could fail when processing corrupt files that have invalid
+      shared message flags (as in CVE-2016-4332).
+
+      The assert statement in question has been replaced with pointer checks
+      that don't raise errors. Since the function is in cleanup code, we do
+      our best to close and free things, even when presented with partially
+      initialized structs.
+
+      Fixes CVE-2016-4332 and HDFFV-9950 (confirmed via the cve_hdf5 repo)
