CVE-2019-17453
Bento4 1.5.1.0 has a NULL pointer dereference in AP4_DescriptorListWriter::Action in Core/Ap4Descriptor.h, related to AP4_IodsAtom::WriteFields in Core/Ap4IodsAtom.cpp, as demonstrated by mp4encrypt or mp4compact.
Does this matter?
Lower severity and a low EPSS score (1.24%). Track it; it rarely justifies an emergency change on its own.
