script_tag(name:"insight", value:"KVM (Kernel-based Virtual Machine) is a full virtualization solution for
Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides the
user-space component for running virtual machines using KVM.
It was found that the QEMU's websocket frame decoder processed incoming
frames without limiting resources used to process the header and the
payload. An attacker able to access a guest's VNC console could use this
flaw to trigger a denial of service on the host by exhausting all available
memory and CPU. (CVE-2015-1779)
This issue was discovered by Daniel P. Berrange of Red Hat.
All qemu-kvm users are advised to upgrade to these updated packages, which
contain a backported patch to correct 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.");
