Descriptions

It was found that vdsm before version 4.20.37 invokes qemu-img on untrusted inputs without limiting resources. By uploading a specially crafted image, an attacker could cause the qemu-img process to consume unbounded amounts of memory of CPU time, causing a denial of service condition that could potentially impact other users of the host.

Se ha detectado que vdsm en versiones anteriores a la 4.20.37 invoca qemu-img en entradas no fiables sin limitar recursos. Mediante la subida de una imagen especialmente manipulada, un atacante podría provocar que el proceso qemu-img consuma cantidades ilimitadas de memoria del tiempo de CPU, provocando una denegación de servicio (DoS) que podría afectar a otros usuarios del host.
