CVE-2025-55667
A segmentation violation in the dump_isom_saps function (/mp4box/filedump.c) of GPAC MP4Box v2.5-DEV-rev1672-gc9a31d0e1-masterallows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
Does this matter?
Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
