Updated qemu-kvm-rhev packages that fix one security issue are now available for Red Hat Enterprise Virtualization Hypervisor 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the user-space component for running virtual machines using KVM.

An information leak flaw was found in the way QEMU’s RTL8139 emulation implementation processed network packets under RTL8139 controller’s C+ mode of operation. An unprivileged guest user could use this flaw to read up to 65 KB of uninitialized QEMU heap memory. (CVE-2015-5165)

Red Hat would like to thank the Xen project for reporting this issue.
Upstream acknowledges Donghai Zhu of Alibaba as the original reporter.

All qemu-kvm-rhev users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
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.
