      "value": "github.com/sylabs/scs-library-client is the Go client for the Singularity Container Services (SCS) Container Library Service. When the scs-library-client is used to pull a container image, with authentication, the HTTP Authorization header sent by the client to the library service may be incorrectly leaked to an S3 backing storage provider. This occurs in a specific flow, where the library service redirects the client to a backing S3 storage server, to perform a multi-part concurrent download. Depending on site configuration, the S3 service may be provided by a third party. An attacker with access to the S3 service may be able to extract user credentials, allowing them to impersonate the user. The vulnerable multi-part concurrent download flow, with redirect to S3, is only used when communicating with a Singularity Enterprise 1.x installation, or third party server implementing this flow. Interaction with Singularity Enterprise 2.x, and Singularity Container Services (cloud.sylabs.io), does not trigger the vulnerable flow. We encourage all users to update. Users who interact with a Singularity Enterprise 1.x installation, using a 3rd party S3 storage service, are advised to revoke and recreate their authentication tokens within Singularity Enterprise. There is no workaround available at this time."

      "value": "github.com/sylabs/scs-library-client es el cliente Go para el servicio de librería de contenedores Singularity Container Services (SCS). Cuando se utiliza scs-library-client para extraer una imagen de contenedor, con autenticación, el encabezado de autorización HTTP enviado por el cliente al servicio de librería puede filtrarse incorrectamente a un proveedor de almacenamiento de respaldo S3. Esto ocurre en un flujo específico, donde el servicio de librería redirige al cliente a un servidor de almacenamiento S3 de respaldo para realizar una descarga simultánea de varias partes. Dependiendo de la configuración del sitio, el servicio S3 puede ser proporcionado por un tercero. Un atacante con acceso al servicio S3 puede extraer las credenciales del usuario, lo que le permitirá hacerse pasar por el usuario. El flujo de descarga simultánea de varias partes vulnerable, con redireccionamiento a S3, solo se usa cuando se comunica con una instalación de Singularity Enterprise 1.x o un servidor de terceros que implementa este flujo. La interacción con Singularity Enterprise 2.x y Singularity Container Services (cloud.sylabs.io) no desencadena el flujo vulnerable. Animamos a todos los usuarios a actualizar. Se recomienda a los usuarios que interactúan con una instalación de Singularity Enterprise 1.x, utilizando un servicio de almacenamiento S3 de terceros, que revoquen y vuelvan a crear sus tokens de autenticación dentro de Singularity Enterprise. No hay ningún workaround en este momento."
