Summary
Red Hat Security Advisory: qemu-kvm-rhev security and bug fix update

Notes

Topic
An update for qemu-kvm-rhev is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 7 and Red Hat Virtualization Engine 4.3. 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.
Details
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): * QEMU: slirp: heap buffer overflow during packet reassembly (CVE-2019-14378) * QEMU: qxl: null pointer dereference while releasing spice resources (CVE-2019-12155) 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): * ccid: Fix incorrect dwProtocol advertisement of T=0 (BZ#1729880) * QEMU gets stuck on resume/cont call from libvirt (BZ#1741937) * [v2v] Migration performance regression (BZ#1743322) * qemu, qemu-img fail to detect alignment with XFS and Gluster/XFS on 4k block device (BZ#1745443) * qemu-kvm: backport cpuidle-haltpoll support (BZ#1746282) * qemu aborts in blockCommit: qemu-kvm: block.c:3486 (BZ#1750322)
