Descriptions

A flaw was found in the QEMU disk image utility (qemu-img) 'info' command. A specially crafted image file containing a `json:{}` value describing block devices in QMP could cause the qemu-img process on the host to consume large amounts of memory or CPU time, leading to denial of service or read/write to an existing external file.

Se encontró una falla en el comando 'info' de la utilidad de imagen de disco QEMU (qemu-img). Un archivo de imagen especialmente manipulado que contenga un valor `json:{}` que describa los dispositivos de bloque en QMP podría provocar que el proceso qemu-img en el host consuma grandes cantidades de memoria o tiempo de CPU, lo que provocaría una denegación de servicio o lectura/escritura en un archivo externo existente.
