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 Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.
