CVE-2025-60477Public exploit

Process crash via unchecked NULL metadata string

Published Jun 3, 2026 · Updated Jun 3, 2026

NULL pointer dereference in GPAC MP4Box before 26.02.0 allows attackers to crash the process by supplying a crafted media file. In gf_filter_pid_resolve_file_template_ex, crafted metadata can leave a file-path property's string value NULL, but the function passes it to strncmp without checking it. Exploitation requires MP4Box to process the file during DASH generation; the observed outcome is a segmentation fault and service interrupt, with no reported data disclosure or modification.
