virtualization solution for Linux on a variety of architectures. The qemu-kvm
package provides the user-space component for running virtual machines that use
KVM. Security Fix(es): * An out-of-bounds memory access issue was found in Quick
Emulator (QEMU) in the VNC display driver. This flaw could occur while
refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A
user inside a guest could use this flaw to crash the QEMU process.
(CVE-2017-2633) * An integer overflow flaw was found in Quick Emulator (QEMU) in
the CCID Card device support. The flaw could occur while passing messages via
command/response packets to and from the host. A privileged user inside a guest
could use this flaw to crash the QEMU process. (CVE-2017-5898) * An information
exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR)
optimizations for 32-bit Windows guests. The flaw could occur while accessing
TPR. A privileged user inside a guest could use this issue to read portions of
the host memory. (CVE-2016-4020) Red Hat would like to thank Li Qiang (360.cn
Inc.) for reporting CVE-2017-5898 and Donghai Zdh (Alibaba Inc.) for reporting
CVE-2016-4020. Additional Changes: For detailed information on changes in this
release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the
