The new Fedora 23 patch addresses external denial-of-service vulnerabilities in qemu and fixes coroutine reentrancy issues. Get the update via yum package manager
* Rebased to version 2.4.0.1 * CVE-2015-7295: virtio-net possible remote DoS (bz #1264393) * drive-mirror: Fix coroutine reentrance (bz #1266936)

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:

* Rebased to version 2.4.0.1 * CVE-2015-7295: virtio-net possible remote DoS (bz #1264393) * drive-mirror: Fix coroutine reentrance (bz #1266936)
