| Description: | KVM (Kernel-based Virtual Machine) is a full virtualization solution forLinux on AMD64 and Intel 64 systems. The qemu-kvm package provides theuser-space component for running virtual machines using KVM.Two integer overflow flaws were found in the QEMU block driver for QCOWversion 1 disk images. A user able to alter the QEMU disk image filesloaded by a guest could use either of these flaws to corrupt QEMU processmemory on the host, which could potentially result in arbitrary codeexecution on the host with the privileges of the QEMU process.(CVE-2014-0222, CVE-2014-0223)Multiple buffer overflow, input validation, and out-of-bounds write flawswere found in the way virtio, virtio-net, virtio-scsi, usb, and hpetdrivers of QEMU handled state loading after migration. A user able to alterthe savevm data (either on the disk or over the wire during migration)could use either of these flaws to corrupt QEMU process memory on the(destination) host, which could potentially result in arbitrary codeexecution on the host with the privileges of the QEMU process.(CVE-2013-4148, CVE-2013-4149, CVE-2013-4150, CVE-2013-4151, CVE-2013-4527,CVE-2013-4529, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541, CVE-2013-4542,CVE-2013-6399, CVE-2014-0182, CVE-2014-3461)These issues were discovered by Michael S. Tsirkin, Anthony Liguori andMichael Roth of Red Hat: CVE-2013-4148, CVE-2013-4149, CVE-2013-4150,CVE-2013-4151, CVE-2013-4527, CVE-2013-4529, CVE-2013-4535, CVE-2013-4536,CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, andCVE-2014-3461. |
