Upgrade RHEL:8 virt:rhel/seavgabios-bin to version 0:1.11.1-3.module+el8.0.0+3075+09be6b65 or higher.
This issue was patched in RHSA-2019:1175.

NVD Description

Note: Versions mentioned in the description apply only to the upstream virt:rhel/seavgabios-bin package and not the virt:rhel/seavgabios-bin package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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