Fedora 23: qemu Security Update 2015-16370
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-2015-6815: net: e1000: infinite loop issue (bz #1260225) * CVE-2015-6855: ide: divide by zero issue (bz #1261793) * CVE-2015-5278: Infinite loop in ne2000_receive() (bz #1263284) * CVE-2015-5279: Heap overflow vulnerability in ne2000_receive() (bz #1263287) ---- Fix emulation of various instructions, required by libm in F22 ppc64 guests.
