Rating: moderate
References: #1094898 #1098735 #1102604 #1103628 #1105279

______________________________________________________________________________
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)
