AP4_VisualSampleEntry::ReadFields in Core/Ap4SampleEntry.cpp in Bento4 1.5.0-617 uses incorrect character data types, which causes a stack-based buffer underflow and out-of-bounds write, leading to denial of service (application crash) or possibly unspecified other impact.
The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type.
