Fedora 27: qemu Security Update
Summary
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.
* Fix ppc64 KVM failure (bz #1501936) * CVE-2017-15038: 9p: information
disclosure when reading extended attributes (bz #1499111) * CVE-2017-15268:
potential memory exhaustion via websock connection to VNC (bz #1496882) ----qemu-pr-helper didn't work due to a change in the libmultipath/libmpathpersist
APIs exposed by device-mapper-multipath-devel. This has been fixed now. Other
small changes to the qemu-pr-helper service are included. ---- Backport qemu-pr-helper from QEMU 2.11. This daemon allows unprivileged users (who have
access to the daemon) to use persistent reservation commands on both regular
disks and multipath block devices.
