RHEL 7 : util-linux (RHSA-2016:2605)

medium Nessus Plugin ID 94568

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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.
