+Subject: [PATCH 1/3] ANI: Reject files with multiple anih chunks
+
+An anih chunk causes us to initialize a bunch of state, which we only
+expect to do once per file.

+
+There should be at most one chunk each.  These would cause memory leaks

+Subject: [PATCH 3/3] ANI: Validate anih chunk size
+
+Before reading a chunk, we verify that enough bytes are available to match
+the chunk size declared by the file.  However, uniquely, the anih chunk
+loader doesn't verify that this size matches the number of bytes it
+actually intends to read.  Thus, if the chunk size is too small and the
+file ends in the middle of the chunk, we populate some context fields with
+stack garbage.  (But we'd still fail later on because the file doesn't
+contain any images.)  Fix this.
