-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: qemu-kvm-ma security and bug fix update Advisory ID: RHSA-2019:1881-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2019:1881 Issue date: 2019-07-29 CVE Names: CVE-2018-20815 ==================================================================== 1. Summary: An update for qemu-kvm-ma is now available for Red Hat Enterprise Linux 7. 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 Server (v. 7) - ppc64, ppc64le, s390x Red Hat Enterprise Linux Server Optional (v. 7) - ppc64 Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) - ppc64le, s390x Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64 3. Description: Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of architectures. The qemu-kvm-ma packages provide the user-space component for running virtual machines that use KVM on the IBM z Systems, IBM Power, and 64-bit ARM architectures. Security Fix(es): * QEMU: device_tree: heap buffer overflow while loading device tree blob (CVE-2018-20815) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * As newer machine remove csske feature, detection of the processor fail and machine used old version as fallback. This update make feature conditional so detection of newer cpu works properly. (BZ#1720262) 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.
