33025 "This security bug concerns the automatic disk format detection that qemu "
33026 "does on disk images."
33030 #: ../src/guestfs.pod:1234
33032 "A raw disk image is just the raw bytes, there is no header. Other disk "
33033 "images like qcow2 contain a special header. Qemu deals with this by looking "
33034 "for one of the known headers, and if none is found then assuming the disk "
33035 "image must be raw."
33039 #: ../src/guestfs.pod:1239
33041 "This allows a guest which has been given a raw disk image to write some "
33042 "other header. At next boot (or when the disk image is accessed by "
33043 "libguestfs) qemu would do autodetection and think the disk image format was, "
33044 "say, qcow2 based on the header written by the guest."
33048 #: ../src/guestfs.pod:1244
33050 "This in itself would not be a problem, but qcow2 offers many features, one "
33051 "of which is to allow a disk image to refer to another image (called the "
33052 "\"backing disk\"). It does this by placing the path to the backing disk "
33053 "into the qcow2 header. This path is not validated and could point to any "
33054 "host file (eg. \"/etc/passwd\"). The backing disk is then exposed through "
33055 "\"holes\" in the qcow2 disk image, which of course is completely under the "
33056 "control of the attacker."
