Fedora 21: 2015-9599 Critical: QEMU Insecure File Use Update

fedora
Calendar Grey June 21, 2015
Dist Fedora Esm H88
Update for QEMU on Fedora 21 aimed at resolving serious vulnerabilities, such as unsafe file handling and user interface lockup within Xfig.
* User interface freezes when entering space character in Xfig (bz #1151253) * CVE-2015-4037: insecure temporary file use in /net/slirp.c (bz #1222894) * Backport {Haswell,Broadwel...

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:

* User interface freezes when entering space character in Xfig (bz #1151253) * CVE-2015-4037: insecure temporary file use in /net/slirp.c (bz #1222894) * Backport {Haswell,Broadwell}-noTSX cpu models (bz #1213053)
