The qemu-kvm-rhev package provides the\nuser-space component for running virtual machines using KVM in environments\nmanaged by Red Hat Enterprise Virtualization Manager.\n\nTwo integer overflow flaws were found in the QEMU block driver for QCOW\nversion 1 disk images. A user able to alter the QEMU disk image files\nloaded by a guest could use either of these flaws to corrupt QEMU process\nmemory on the host, which could potentially result in arbitrary code\nexecution on the host with the privileges of the QEMU process.\n(CVE-2014-0222, CVE-2014-0223)\n\nRed Hat would like to thank NSA for reporting these issues.\n\nThis update also fixes the following bug:\n\n* In certain scenarios, when performing live incremental migration, the\ndisk size could be expanded considerably due to the transfer of unallocated\nsectors past the end of the base image. With this update, the\nbdrv_is_allocated() function has been fixed to no longer return \"True\" for\nunallocated sectors, and the disk size no longer changes after performing\nlive incremental migration. (BZ#1110681)\n\nAll users of qemu-kvm-rhev are advised to upgrade to these updated\npackages, which contain backported patches to correct these issues. After\ninstalling this update, shut down all running virtual machines. Once all\nvirtual machines have shut down, start them again for this update to take\neffect.",
