Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2018:2388-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2018:2388
Issue date: 2018-08-14
CVE Names: CVE-2018-3620 CVE-2018-3646
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 7.3
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. 7.3) – noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.3) – x86_64
Red Hat Enterprise Linux Server EUS (v. 7.3) – noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.3) – ppc64, ppc64le, x86_64

3. Description:

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

Security Fix(es):

* Modern operating systems implement virtualization of physical memory to
efficiently use available system resources and provide inter-domain
protection through access control and isolation. The L1TF issue was found
in the way the x86 microprocessor designs have implemented speculative
execution of instructions (a commonly used performance optimisation) in
combination with handling of page-faults caused by terminated virtual to
physical address resolving process. As a result, an unprivileged attacker
could use this flaw to read privileged memory of the kernel or other
processes and/or cross guest/host boundaries to read host memory by
conducting targeted cache side-channel attacks. (CVE-2018-3620,
CVE-2018-3646)

Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting these
issues.

Bug Fix(es):

* Due to a bug in a CPU’s speculative execution engine, the CPU could
previously leak data from other processes on the system, including
passwords, encryption keys, or other sensitive information. With this
update, the kernel build requirements have been updated to the GNU Compiler
Collection (GCC) compiler version that has the support for Expoline for IBM
z Systems. As a result, data leak no longer occurs under the described
circumstances. (BZ#1577761)

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

The system must be rebooted for this update to take effect.

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

1585005 – CVE-2018-3646 Kernel: hw: cpu: L1 terminal fault (L1TF)
