qemu-kvm-1.5.3-126.el7.9

qemu-kvm is an open source virtualizer that provides hardware emulation for
the KVM hypervisor. qemu-kvm acts as a virtual machine monitor together with
the KVM kernel modules, and emulates the hardware for a full system such as
a PC and its assocated peripherals.

As qemu-kvm requires no host kernel patches to run, it is safe and easy to use.

Security issues fixed with this release:

CVE-2017-7718
hw/display/cirrus_vga_rop.h in QEMU (aka Quick Emulator) allows local
guest OS privileged users to cause a denial of service (out-of-bounds
read and QEMU process crash) via vectors related to copying VGA data
via the cirrus_bitblt_rop_fwd_transp_ and cirrus_bitblt_rop_fwd_
functions.
CVE-2017-7980
** RESERVED **
This candidate has been reserved by an organization or individual that
will use it when announcing a new security problem. When the
candidate has been publicized, the details for this candidate will be
provided.

Fixed bugs:

* Previously, guest virtual machines in some cases became unresponsive when the "pty" back end of a serial device performed an irregular I/O communication. This update improves the handling of serial I/O on guests, which prevents the described problem from occurring.
