CWE-122  (opens in a new tab)

How to fix?

Upgrade Centos:8 sgabios-bin to version 1:0.20170427git-2.module+el8.0.0+3075+09be6b65 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream sgabios-bin package and not the sgabios-bin package as distributed by Centos. See How to fix? for Centos: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.
