------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2017-8db9c497f9 2017-11-11 01:32:26.765894 ------------------------------------------------------------------------------- -
Name : qemu Product : Fedora 27 Version : 2.10.1 Release : 1.fc27 URL : http://www.qemu.org/ Summary : QEMU is a FAST! processor emulator Description : 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 ppc64 KVM failure (bz #1501936) * CVE-2017-15038: 9p: information disclosure when reading extended attributes (bz #1499111) * CVE-2017-15268: potential memory exhaustion via websock connection to VNC (bz #1496882) ---- qemu-pr-helper didn't work due to a change in the libmultipath/libmpathpersist APIs exposed by device-mapper-multipath-devel. This has been fixed now. Other small changes to the qemu-pr-helper service are included. ---- Backport qemu- pr-helper from QEMU 2.11. This daemon allows unprivileged users (who have access to the daemon) to use persistent reservation commands on both regular disks and multipath block devices. ------------------------------------------------------------------------------- - References:
