Red Hat Security Advisory

Synopsis: Moderate: util-linux security and bug fix update
Advisory ID: RHSA-2017:0907-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:0907
Issue date: 2017-04-12
CVE Names: CVE-2017-2616
=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client (v. 7) – x86_64
Red Hat Enterprise Linux Client Optional (v. 7) – x86_64
Red Hat Enterprise Linux ComputeNode (v. 7) – x86_64
Red Hat Enterprise Linux ComputeNode Optional (v. 7) – x86_64
Red Hat Enterprise Linux Server (v. 7) – aarch64, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional (v. 7) – aarch64, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 7) – x86_64
Red Hat Enterprise Linux Workstation Optional (v. 7) – x86_64

3. Description:

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 Stöckmann 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)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1414481 – findmnt –target behaviour changed in 7.3, shows all mount-points in chroot
1418710 – CVE-2017-2616 util-linux: Sending SIGKILL to other processes with root privileges via su
