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 " command prints all file systems where the

mount point directory is . Previously, when used in the chroot

environment, "findmnt --target " 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
