CVE:CVE-2013-7336 (The qemuMigrationWaitForSpice function in qemu/qemu_migration.c in libvirt before 1.1.3 does not properly enter a monitor when performing seamless SPICE migration, which allows local users to cause a denial of service (NULL pointer dereference and libvirtd crash) by causing domblkstat to be called at the same time as the qemuMonitorGetSpiceMigrationStatus function.)
 CVE-2013-6456 (The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through 1.2.1 allows local users to (1) delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; (2) create arbitrary nodes (mknod) via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a symlink attack on /dev/initctl in the container, related to "paths under /proc/$PID/root" and the virInitctlSetRunLevel function.)
