NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-img package and not the qemu-img package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two addresses, which allows attackers to trigger an invalid memory copy operation.
