"value": "In snapd versions prior to 2.62, snapd failed to properly check the file\ntype when extracting a snap. The snap format is a squashfs file-system\nimage and so can contain files that are non-regular files (such as pipes \nor sockets etc). Various file entries within the snap squashfs image\n(such as icons etc) are directly read by snapd when it is extracted. An \nattacker who could convince a user to install a malicious snap which\ncontained non-regular files at these paths could then cause snapd to block\nindefinitely trying to read from such files and cause a denial of service."

"value": "En versiones de snapd anteriores a la 2.62, snapd no pudo verificar correctamente el tipo de archivo al extraer un complemento. El formato snap es una imagen del sistema de archivos squashfs y, por lo tanto, puede contener archivos que no son archivos regulares (como tuber\u00edas o enchufes, etc.). Snapd lee directamente varias entradas de archivos dentro de la imagen de snap squashfs (como \u00edconos, etc.) cuando se extrae. Un atacante que pudiera convencer a un usuario de que instalara un complemento malicioso que contuviera archivos no regulares en estas rutas podr\u00eda provocar que snapd bloqueara indefinidamente el intento de leer dichos archivos y provocar una denegaci\u00f3n de servicio."
