RHEL 7 : util-linux (RHSA-2017:0907)

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


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 Moderate. 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) :

* A race condition was found in the way su handled the management of
child processes. A local authenticated attacker could use this flaw to
kill other processes with root privileges under specific conditions.
(CVE-2017-2616)

Red Hat would like to thank Tobias Stockmann for reporting this
issue.

Bug Fix(es) :

* The 'findmnt --target <path>' command prints all file systems where
the mount point directory is <path>. Previously, when used in the
chroot environment, 'findmnt --target <path>' incorrectly displayed
all mount points. The command has been fixed so that it now checks the
mount point path and returns information only for the relevant mount
point. (BZ#1414481)
