The latest QEMU security update for Fedora 22 fixes serious vulnerabilities impacting system security, including integer overflow issues and network vulnerabilities.
* CVE-2016-2538: Integer overflow in usb module (bz #1305815) * CVE-2016-2841: ne2000: infinite loop (bz #1304047) * CVE-2016-2857: net: out of bounds read (bz #1309564) * CVE-2016...

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-2016-2538: Integer overflow in usb module (bz #1305815) * CVE-2016-2841: ne2000: infinite loop (bz #1304047) * CVE-2016-2857: net: out of bounds read (bz #1309564) * CVE-2016-2392: usb: null pointer dereference (bz #1307115) * spice: fix spice_chr_add_watch() crash (bz #1315049)
