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

Subject: [PATCH] Fixed OOB read when loading invalid ogg flac file. (#868)
This CVE 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.
Upstream-Status: Backport
