Fedora 25 Moderate: Fix QEMU Memory Leak and Other Issues

QEMU is a generic and open source processor emulator which achieves a good

emulation speed by using dynamic translation. QEMU has two operating modes:

* Full system emulation. In this mode, QEMU emulates a full system (for

example a PC), including a processor and various peripherials. It can be

used to launch different Operating Systems without rebooting the PC or

to debug system code.

* User mode emulation. In this mode, QEMU can launch Linux processes compiled

for one CPU on another CPU.

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

* chardev data is dropped when host side closed (bz #1352977) * CVE-2016-8667:

dma: divide by zero error in set_next_tick (bz #1384876) * IPv6 DNS problems in

qemu user networking (bz #1401165) * Fix crash in qxl memslot_get_virt (bz

#1405847) * CVE-2017-5579: serial: fix memory leak in serial exit (bz #1416161)

* spec: Pull in ipxe/vgabios links via -common package (bz #1431403) * Clean up

binfmt.d configuration files (bz #1394859)
