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-2015-1779 vnc: insufficient resource limiting in VNC websockets decoder (bz #1205051, bz #1199572) * Qemu: PRDT overflow from guest to host (bz #1204919, bz #1205322) * CVE-2014-8106: cirrus: insufficient blit region checks (bz #1170612, bz #1169454) * Fix .vdi disk corruption (bz #1199400) * Don't install ksm services as executable (bz #1192720) -------------------------------------------------------------------------------- ChangeLog: * Thu Apr 2 2015 Cole Robinson - 2:2.1.3-5 - CVE-2015-1779 vnc: insufficient resource limiting in VNC websockets decoder (bz #1205051,bz #1199572) * Fri Mar 27 2015 Cole Robinson - 2:2.1.3-4 - Qemu: PRDT overflow from guest to host (bz #1204919, bz #1205322) - CVE-2014-8106: cirrus: insufficient blit region checks (bz #1170612, bz - Fix .vdi disk corruption (bz #1199400) - Don't install ksm services as executable (bz #1192720) * Tue Mar 10 2015 Haïkel Guémar - 2:2.1.3-3 - Backport upstream patch fixing some qemu-img conversion errors (RHBZ#1200043) * Sat Feb 7 2015 Cole Robinson - 2:2.1.3-2 - Fix USB host assignment (bz #1187749) * Wed Jan 28 2015 Cole Robinson - 2:2.1.3-1 - Rebased to version 2.1.3 * Wed Jan 28 2015 Daniel P.
