Technical details

The dvdnav_describe_title_chapters function contains a heap out-of-bounds read vulnerability triggered by an oversized vts_ttn value in the VMGI (Video Manager Information) header. An attacker can craft a disc image declaring a larger VMGI title vts_ttn than the actual number of title set entries, allowing reads past the part-of-title array boundary. A fix exists in version 7.0.0 and later.
