NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-system-aarch64 package and not the qemu-system-aarch64 package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

A flaw was found in the QXL display device emulation in QEMU. A double fetch of guest controlled values cursor-&gt;header.width and cursor-&gt;header.height can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.
