| Title | gpac v2.4.0 NULL Pointer Dereference |
|---|
| Description | A NULL pointer dereference vulnerability exists in the DumpMovieInfo() function in applications/mp4box/filedump.c. When processing a crafted MP4 file containing a chapter track with an empty text sample (text_length = 0), the txt->text pointer is NULL and is passed directly to fprintf() with the %s format specifier, resulting in undefined behavior. |
