   An update that solves one vulnerability and has four fixes
   is now available.

Description:

   This update for qemu fixes the following issues:

   This security issue was fixed:

   - CVE-2018-12617: qmp_guest_file_read had an integer overflow that could
     have been exploited by sending a crafted QMP command (including
     guest-file-read with a large count value) to the agent via the listening
     socket causing DoS (bsc#1098735)

   These non-security issues were fixed:

   - Allow kvm group access to /dev/sev (bsc#1102604).
   - Fix for the value used for reduced_phys_bits.  Please update the
     reduced_phys_bits value used on the commandline or in libvirt XML to the
     value 1 (explicitly set now in QEMU code). (bsc#1103628)
   - Fix (again) the qemu guest agent udev rule file, which got unfixed in a
     series of unfortunate events (bsc#1094898 and now bsc#1105279)
