+Subject: [PATCH] Don't assume TDRC is an instance of TextIdentificationFrame
+ (#831)
+
+If TDRC is encrypted, FrameFactory::createFrame() returns UnknownFrame
+which causes problems in rebuildAggregateFrames() when it is assumed
+that TDRC is a TextIdentificationFrame

+Subject: [PATCH] Fixed OOB read when loading invalid ogg flac file. (#868)
+ (#869)
+
+CVE-2018-11439 is caused by a failure to check the minimum length
+of a ogg flac header. This header is detailed in full at:
+https://xiph.org/flac/ogg_mapping.html. Added more strict checking
+for entire header.
