Synopsis:          Important: qemu-kvm-rhev security update
Advisory ID:       RHSA-2018:1643-01
Product:           Red Hat Enterprise Linux OpenStack Platform
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:1643
Issue date:        2018-05-21
CVE Names:         CVE-2018-3639 
=====================================================================

1. Summary:

An update for qemu-kvm-rhev is now available for Red Hat OpenStack Platform
12.0 (Pike).

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 OpenStack Platform 12.0 - ppc64le, x86_64

3. Description:

KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on a variety of architectures. The qemu-kvm-rhev packages provide the
user-space component for running virtual machines that use KVM in
environments managed by Red Hat products.

Security Fix(es):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of Load & Store instructions
(a commonly used performance optimization). It relies on the presence of a
precisely-defined instruction sequence in the privileged code as well as
the fact that memory read from address to which a recent memory write has
occurred may see an older value and subsequently cause an update into the
microprocessor's data cache even for speculatively executed instructions
that never actually commit (retire). As a result, an unprivileged attacker
could use this flaw to read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2018-3639)

Note: This is the qemu-kvm-rhev side of the CVE-2018-3639 mitigation.

Red Hat would like to thank Ken Johnson (Microsoft Security Response
Center) and Jann Horn (Google Project Zero) for reporting this issue.

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

After installing this update, shut down all running virtual machines. Once
all virtual machines have shut down, start them again for this update to
take effect.

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

Linux on a variety of architectures. The qemu-kvm-rhev packages provide the
user-space component for running virtual machines that use KVM in
environments managed by Red Hat products.

Security Fix(es):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of Load & Store instructions
(a commonly used performance optimization). It relies on the presence of a
precisely-defined instruction sequence in the privileged code as well as
the fact that memory read from address to which a recent memory write has
occurred may see an older value and subsequently cause an update into the
microprocessor's data cache even for speculatively executed instructions
that never actually commit (retire). As a result, an unprivileged attacker
could use this flaw to read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2018-3639)

Note: This is the qemu-kvm-rhev side of the CVE-2018-3639 mitigation.

Red Hat would like to thank Ken Johnson (Microsoft Security Response
Center) and Jann Horn (Google Project Zero) for reporting this issue.

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

After installing this update, shut down all running virtual machines. Once
all virtual machines have shut down, start them again for this update to
take effect.
