Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for qemu fixes the following security issues :

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)

CVE-2018-11806: Prevent heap-based buffer overflow via incoming fragmented datagrams (bsc#1096223)

With this release the mitigations for Spectre v4 are moved the the patches from upstream (CVE-2018-3639, bsc#1092885).
