Fedora 22 QEMU Update: 2015-d5c1048b47 Critical Remote DoS Fix

Dist Fedora Esm H88
Fedora 22 releases crucial QEMU security patch tackling CVE-2015-7295 alongside various significant performance improvements.
* CVE-2015-7295: virtio-net possible remote DoS (bz #1264393) * drive-mirror: Fix coroutine reentrance (bz #1266936) * Fix udp socket 'localaddr' (bz #1268708)

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.

Update Information:

* CVE-2015-7295: virtio-net possible remote DoS (bz #1264393) * drive-mirror: Fix coroutine reentrance (bz #1266936) * Fix udp socket 'localaddr' (bz #1268708)
