Prior to version 7.2.0, an arbitrary file write exists in the Incus client when a malicious image server returns a crafted `Incus-Image-Hash` header. This can lead to arbitrary command execution as root on the server. Version 7.2.0 patches the issue."

Antes de la versión 7.2.0, existe una escritura de archivo arbitraria en el cliente Incus cuando un servidor de imágenes malicioso devuelve una cabecera 'Incus-Image-Hash' manipulada. Esto puede llevar a la ejecución arbitraria de comandos como root en el servidor. La versión 7.2.0 corrige el problema."
