Summary
Red Hat Security Advisory: qemu-kvm-rhev security, bug fix, and enhancement 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: block: iscsi: OOB heap access via an unexpected response of iSCSI Server (CVE-2020-1711)
* 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):
* After host update, older windows clients have large time drift (BZ#1639098)
* [v2v] Migration performance regression (BZ#1648622)

* ccid: Fix incorrect dwProtocol advertisement of T=0 (BZ#1721522)
* Fail to migrate a rhel6.10-mt7.6 guest with dimm device (BZ#1724048)
* qemu-kvm: backport cpuidle-haltpoll support (BZ#1734502)
* qemu, qemu-img fail to detect alignment with XFS and Gluster/XFS on 4k block device (BZ#1743365)
* ISST-LTE:RHV4.3 on RHEL7.6 kvm host:Power8:Tuleta-L:lotg7: call traces dumped on guest while performing guest migration (qemu-kvm-rhev) (BZ#1743508)
* qemu coredump: qemu-kvm: block/create.c:68: qmp_blockdev_create: Assertion `drv' failed (BZ#1746224)
* [Data plane]virtio_scsi_ctx_check: Assertion `blk_get_aio_context(d->conf.blk) == s->ctx' failed when unplug a device that running block stream on it (BZ#1764120)
* qemu-kvm crashes when Windows VM is migrated with multiqueue (BZ#1775251)
Enhancement(s):
* [Intel 7.8 FEAT] MDS_NO exposure to guest - qemu-kvm-rhev (BZ#1716726)
