3. Description:
KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm 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 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.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
