Issue date: 2017-03-15
CVE Names: CVE-2016-7545
=====================================================================

1. Summary:

An update for policycoreutils is now available for Red Hat Enterprise Linux
7.2 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact
of Important. 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 ComputeNode EUS (v. 7.2) – x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.2) – x86_64
Red Hat Enterprise Linux Server EUS (v. 7.2) – ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.2) – ppc64, ppc64le, s390x, x86_64

3. Description:

The policycoreutils packages contain the core policy utilities required to
manage a SELinux environment.

Security Fix(es):

* It was found that the sandbox tool provided in policycoreutils was
vulnerable to a TIOCSTI ioctl attack. A specially crafted program executed
via the sandbox command could use this flaw to execute arbitrary commands
in the context of the parent shell, escaping the sandbox. (CVE-2016-7545)

4. Solution:

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