Fedora 23: 2015-2773b85b49 Moderate: QEMU Buffer Overflow Issues

QEMU security patch: addresses buffer and heap overflow and infinite loop issues in Fedora 23.
* Fix SSE4 emulation with accel=tcg (bz #1270703) * CVE-2015-8345: Fix infinite loop in eepro100 (bz #1285214) * CVE-2015-7504: Fix heap overflow in pcnet (bz #1286543) * CVE-2015-...

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:

* Fix SSE4 emulation with accel=tcg (bz #1270703) * CVE-2015-8345: Fix infinite loop in eepro100 (bz #1285214) * CVE-2015-7504: Fix heap overflow in pcnet (bz #1286543) * CVE-2015-7512: Fix buffer overflow in pcnet (bz #1286549)
