Description
libdvdnav before 7.0.0 contains a heap out-of-bounds read vulnerability in dvdnav_describe_title_chapters that allows attackers to read beyond the part-of-title array by supplying an oversized vts_ttn value. Attackers can provide a crafted DVD or disc image declaring a larger VMGI title vts_ttn than the title set's entries to crash applications enumerating chapters.
