Oracle Linux 7 : util-linux (ELSA-2016-2605)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2016:2605 :

An update for util-linux is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Low. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The util-linux packages contain a large variety of low-level system
utilities that are necessary for a Linux system to function. Among
others, these include the fdisk configuration tool and the login
program.

Security Fix(es) :

* 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.
(CVE-2016-5011)

Red Hat would like to thank Michael Gruhn for reporting this issue.
Upstream acknowledges Christian Moch as the original reporter.
