A forged NTFS3 image gives any local user root the moment a USB drive is mounted

The Linux kernel’s NTFS3 driver restores setuid bits straight from untrusted on-disk data, letting a crafted NTFS image produce a setuid-root binary as soon as the volume mounts. Reported privately two months ago and still unpatched, the bug hits desktops whose automounter mounts NTFS volumes with suid on by default.
