CVE-2016-5011
It was found that util-linux's libblkid library did not properly handle Extended Boot Record (EBR) partitions when reading MS-DOS partition tables. An attacker with physical USB access to a protected machine could insert a storage device with a specially crafted partition table that could, for example, trigger an infinite loop in systemd-udevd, resulting in a denial of service on that machine.
