Fedora 22: 2015-b406a8e4f2 Moderate: qemu Floating Point Exception Risk

fedora
Calendar Grey December 29, 2015
Dist Fedora Esm H88
A critical QEMU update for Fedora 22 addresses floating point exceptions that could lead to security vulnerabilities. Update your system to stay secure
* vnc: avoid floating point exceptions (bz #1289541, bz #1289542)

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:

* vnc: avoid floating point exceptions (bz #1289541, bz #1289542)
