CVE-2017-14646
The AP4_AvccAtom and AP4_HvccAtom classes in Bento4 version 1.5.0-617 do not properly validate data sizes, leading to a heap-based buffer over-read and application crash in AP4_DataBuffer::SetData in Core/Ap4DataBuffer.cpp.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.21%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
