Description

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.

Qemu emulator built with the RTL8139 emulation support is vulnerable to an
information leakage flaw, while processing network packets under RTL8139
controller's C+ mode of operation. A guest user could use this flaw to read
upto 65KB of uninitialised 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.
