Specifically, checks for rollback attacks are not implemented correctly meaning an attacker can cause clients to install software that is older than the software which the client previously knew to be available, and may include software with known vulnerabilities. In more detail, the client code of go-tuf has several issues in regards to preventing rollback attacks: 1. It does not take into account the content of any previously trusted metadata, if available, before proceeding with updating roles other than the root role (i.e., steps 5.4.3.1 and 5.5.5 of the detailed client workflow). This means that any form of version verification done on the newly-downloaded metadata is made using the default value of zero, which always passes. 2. For both timestamp and snapshot roles, go-tuf saves these metadata files as trusted before verifying if the version of the metafiles they refer to is correct (i.e., steps 5.5.4 and 5.6.4 of the detailed client workflow). A fix is available in version 0.3.0 or newer. No workarounds are known for this issue apart from upgrading."}, {"lang": "es", "value": "go-tuf es una implementaci\u00f3n en Go de El Update Framework (TUF). go-tuf no implementa correctamente el flujo de trabajo del cliente para la actualizaci\u00f3n de los archivos de metadatos para los roles que no sean el rol de root. Espec\u00edficamente, las comprobaciones para los ataques de retroceso no est\u00e1n implementadas correctamente, lo que significa que un atacante puede causar que los clientes instalen software que es m\u00e1s antiguo que el software que el cliente sab\u00eda previamente que estaba disponible, y puede incluir software con vulnerabilidades conocidas. En m\u00e1s detalle, el c\u00f3digo del cliente de go-tuf presenta varios problemas en cuanto a la prevenci\u00f3n de ataques de retroceso: 1. No presenta en cuenta el contenido de cualquier metadato previamente confiable, si est\u00e1 disponible, antes de proceder con la actualizaci\u00f3n de roles que no sean el rol root (es decir, los pasos 5.4.3.1 y 5.5.5 del flujo de trabajo detallado del cliente). Esto significa que cualquier forma de verificaci\u00f3n de la versi\u00f3n realizada en los metadatos reci\u00e9n descargados es realizada usando el valor por defecto de cero, que siempre pasa. 2. Para los roles de marca de tiempo e instant\u00e1nea, go-tuf guarda estos archivos de metadatos como confiables antes de verificar si la versi\u00f3n de los metaficheros a los que son referidos es correcta (es decir, los pasos 5.5.4 y 5.6.4 del flujo de trabajo detallado del cliente). Se presenta una correcci\u00f3n disponible en versi\u00f3n 0.3.0 o m\u00e1s reciente.
