CVE-2016-5011 util-linux vulnerability
Title: util-linux vulnerability
Summary: A util-linux program could be made to crash if it opened a specially
crafted file system.
Christian Moch and Michael Gruhn discovered that the libblkid library
of util-linux did not properly manage memory under certain
circumstances. A local attacker could possibly use this issue
to cause denial of service by consuming all memory through
a specially crafted MSDOS partition table.
Instructions: In general, a standard system update will make all the necessary changes.

util-linux: Extended partition loop in MBR partition table leads to DOS
The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero offset.
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.

Exploit disk image (use with care ... it is hard to get rid of with just Linux)
Description of problem:
By connecting a storage medium containing a specially crafted MBR a local user can cause a Linux system to become unresponsive.
Version-Release number of selected component (if applicable):
CentOS 7
RHEL 7
Ubuntu 14.04
possibly every Linux system
How reproducible:
Always
Steps to Reproduce:
Generate an MBR with two partitions. One primary and one extended. Point the extended partition to the MBR itself.
This generates a loop that will cause a Linux system to repeatedly generate device nodes for the primary partition in the MBR.
Such a prepared disk images can be generated via:
