CVE-2018-20815

In QEMU 3.1.0, load_device_tree in device_tree.c calls the deprecated load_image function, which has a buffer overflow risk.

This update for qemu fixes the following issues:

Security issues fixed:

• CVE-2019-9824: Fixed an information leak in slirp (bsc#1129622)
• CVE-2019-8934: Added method to specify whether or not to expose certain ppc64 host information, which can be considered a security issue (bsc#1126455)
• CVE-2019-3812: Fixed OOB memory access and information leak in virtual monitor interface (bsc#1125721)
• CVE-2018-20815: Fix DOS possibility in device tree processing (bsc#1130675)
• Adjust fix for CVE-2019-8934 (bsc#1126455) to match the latest upstream adjustments for the same. Basically now the security fix is to provide a dummy host-model and host-serial value, which overrides getting that value from the host
• CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091: Added x86 cpu feature 'md-clear' (bsc#1111331)

Other bugs fixed:

• Use a new approach to handling the file input to -smbios option, which accepts either legacy or per-spec formats regardless of the machine type.

This update was imported from the SUSE:SLE-15:Update update project.

These are all security issues fixed in the qemu-6.1.0-32.1 package on the GA media of openSUSE Tumbleweed.
