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.
