  <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)
