Отправить #736541: gpac v2.4.0 NULL Pointer DereferenceИнформация

Названиеgpac v2.4.0 NULL Pointer Dereference
ОписаниеA NULL pointer dereference vulnerability exists in the gf_media_export_webvtt_metadata() function in src/media_tools/media_export.c. When processing a crafted MP4 file containing a track whose handler box (hdlr) has no name field, the handler pointer (nameUTF8) is NULL and is passed directly to gf_fprintf() with the %s format specifier, resulting in undefined behavior.
