Fedora 23: 2016-372bb57df0 Critical: QEMU Integer Overflow Issues

fedora
Calendar Grey March 23, 2016
Dist Fedora Esm H88
Important Fedora 23 patch for QEMU resolves numerous vulnerabilities across several modules efficiently.
* 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)
