Host file access via protocol-prefixed child filenames
Published Jul 2, 2024 · Updated Feb 25, 2026
Improper image-file handling in QEMU allows local users to read or write host files or exhaust host resources through qemu-img info. The command opens qcow2 data files and parses protocol-prefixed child filenames, including json: descriptions, even when inspection requests no I/O. An attacker must supply a crafted image for host-side processing; resulting access is limited to the qemu-img process permissions, while resource consumption can interrupt the host service.
