A Common Vulnerability Scoring System (CVSS) base score,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: qemu-kvm-rhev security update Advisory ID: RHSA-2018:1646-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://access.redhat.com/errata/RHSA-2018:1646 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 8.0 (Liberty). 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 8.0 (Liberty) - 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 thatnever 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/): 1566890 - CVE-2018-3639 hw: cpu: speculative store bypass 6.
