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)

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
