Stefan Walter found that udisks2, a service to access and manipulate
storage devices, could cause denial of service via system crash if a
corrupted or specially crafted ext2/3/4 device or image was mounted,

For Debian 9 stretch, this problem has been fixed in version

We recommend that you upgrade your udisks2 packages.
