Descriptions

The xfs implementation in the Linux kernel before 2.6.35 does not look up inode allocation btrees before reading inode buffers, which allows remote authenticated users to read unlinked files, or read or overwrite disk blocks that are currently assigned to an active file but were previously assigned to an unlinked file, by accessing a stale NFS filehandle.

La implementación xfs en el kernel Linux, en versiones anteriores a la 2.6.35, no busca la asignación de inodes btrees antes de leer los búfer inode, lo que permite a atacantes remotos autenticados leer ficheros no enlazados o leer o sobreescribir bloques de disco que están asignados actualmente a un fichero activo pero que fueron previamente asignados a un fichero no enlazado, accediendo a un manejador de fichero NFS antiguo.
