Service crash via null string dereference
Published Oct 3, 2022 · Updated Aug 3, 2024
NULL-pointer dereference in Bento4 1.6.0-639 allows remote attackers to crash mp4fragment through a crafted MP4 file. During track construction, AP4_TrakAtom passes a null string pointer to strlen while processing malformed file data, triggering a zero-page read. The file must be processed by mp4fragment; the demonstrated consequence is a process abort, with no reported data access or code execution.
