Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

VideoLAN libdvdnav through 7.0.0 contains an out-of-bounds read vulnerability in set_PTT that allows attackers to crash applications by supplying an invalid JumpTT title number checked only by an assert. Attackers can craft a DVD or disc image whose First Play program chain issues JumpTT with title 0 or an oversized number, reading past the heap title table and crashing the player.
