Title
Race condition during concurrent TLS mounts in efs-utils
Summary
efs-utils is a set of Utilities for Amazon Elastic File System (EFS). A potential race condition issue exists within the Amazon EFS mount helper in efs-utils versions v1.34.3 and below. When using TLS to mount file systems, the mount helper allocates a local port for stunnel to receive NFS connections prior to applying the TLS tunnel. In affected versions, concurrent mount operations can allocate the same local port, leading to either failed mount operations or an inappropriate mapping from an EFS customer’s local mount points to that customer’s EFS file systems. This issue is patched in version v1.34.4. There is no recommended work around. We recommend affected users update the installed version of efs-utils to v1.34.4 or later.

Existe un posible problema de condici\u00f3n de ejecuci\u00f3n dentro del asistente de montaje de Amazon EFS en las versiones efs-utils v1.34.3 y anteriores. Cuando se utiliza TLS para montar sistemas de archivos, el asistente de montaje asigna un puerto local para que stunnel reciba conexiones NFS antes de aplicar el t\u00fanel TLS. En las versiones afectadas, las operaciones de montaje simult\u00e1neas pueden asignar el mismo puerto local, lo que provoca operaciones de montaje fallidas o una asignaci\u00f3n inadecuada de los puntos de montaje locales de un cliente de EFS a los sistemas de archivos EFS de ese cliente. Este problema se solucion\u00f3 en la versi\u00f3n v1.34.4. No se recomienda ning\u00fan workaround.
