Red Hat Security Advisory

Synopsis: Important: qemu-kvm-rhev security update
Advisory ID: RHSA-2018:0060-01
Product: Red Hat Enterprise Linux OpenStack Platform
Advisory URL: https://access.redhat.com/errata/RHSA-2018:0060
Issue date: 2018-01-05
=====================================================================

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:

Kernel-based Virtual Machine (KVM) 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 instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation 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 cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715)

Note: This is the qemu-kvm-rhev side of the CVE-2017-5715 mitigation.

Red Hat would like to thank 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/):

1519780 – CVE-2017-5715 hw: cpu: speculative execution branch target injection
1525497 – QEMU’s AIO subsystem gets stuck inhibiting all I/O operations on virtio-blk-pci devices [OSP 12]
