Fedora 22: 2015-05-14 Moderate Security Update for QEMU (VENOM)

fedora
Calendar Grey May 26, 2015
Dist Fedora Esm H88
Important patch released for Fedora 22 to mitigate the CVE-2015-3456 VENOM flaw affecting QEMU's handling of FIFO buffer memory operations.
* CVE-2015-3456: (VENOM) fdc: out-of-bounds fifo buffer memory access (bz #1221152)

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-2015-3456: (VENOM) fdc: out-of-bounds fifo buffer memory access (bz #1221152)
