Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2017:1233-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:1233
Issue date: 2017-05-16
CVE Names: CVE-2017-2636
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 6.7
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 HPC Node EUS (v. 6.7) – noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) – x86_64
Red Hat Enterprise Linux Server EUS (v. 6.7) – i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 6.7) – i386, ppc64, s390x, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

* A race condition flaw was found in the N_HLDC Linux kernel driver when
accessing n_hdlc.tbuf list that can lead to double free. A local,
unprivileged user able to set the HDLC line discipline on the tty device
could use this flaw to increase their privileges on the system.
(CVE-2017-2636, Important)

Red Hat would like to thank Alexander Popov for reporting this issue.

4. Solution:

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