SECURITY UPDATE: Heap buffer overflow in the little-endian byte-swap of MIME magic values
debian/patches/CVE-2026-16118.patch: parenthesize (ptr + i) before the cast so the write side of the byte-swap uses byte offsets instead of scaling by the word size in _xdg_mime_magic_parse_magic_line() in gio/xdgmime/xdgmimemagic.c
