Título:	RedHat Security Advisory RHSA-2011:0345
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2011:0345. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on AMD64 and Intel 64 systems. qemu-kvm is the user-space component for running virtual machines using KVM. Virtual Network Computing (VNC) is a remote display system. A flaw was found in the way the VNC password option was handled. Clearing a password disabled VNC authentication, allowing a remote user able to connect to the virtual machines' VNC ports to open a VNC session without authentication. (CVE-2011-0011) All users of qemu-kvm should upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing this update, shut down all running virtual machines. Once all virtual machines have shut down, start them again for this update to take effect. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2011-0345.html Risk factor : Medium
