  "summary": "Updated qemu packages fix security vulnerability",
  "details": "It was found that QEMU Guest Agent (the \"qemu-ga\" service) created\ncertain files with world-writable permissions when run in daemon mode\n(the default mode). An unprivileged guest user could use this flaw to\nconsume all free space on the partition containing the qemu-ga log file, or\nmodify the contents of the log. When a UNIX domain socket transport was\nexplicitly configured to be used (not the default), an unprivileged guest\nuser could potentially use this flaw to escalate their privileges in the\nguest (CVE-2013-2007).\n\nNote:  This update requires manual action. Refer below for details.\n\nThis update does not change the permissions of the existing log file or\nthe UNIX domain socket. For these to be changed, stop the qemu-ga service,\nand then manually remove all \"group\" and \"other\" permissions on the\naffected files, or remove the files.\n\nAlso note that after installing this update, files created by the\nguest-file-open QEMU Monitor Protocol (QMP) command will still continue to\nbe created with world-writable permissions for backwards compatibility.\n",
