qemu-kvm-1.5.3-126.el7.5

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.

CVE-2017-2620
** 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:

* When using the virtio-blk driver on a guest virtual machine with no space on the virtual hard drive, the guest terminated unexpectedly with a "block I/O error in device" message and the qemu-kvm process exited with a segmentation fault. This update fixes how the system_reset QEMU signal is handled in the above scenario. As a result, if a guest crashes due to no space left on the device, qemu-kvm continues running and the guest can be reset as expected.
