The transform_save function in transform.c in Augeas before 1.0.0 allows local users to overwrite arbitrary files and obtain sensitive information via a symlink attack on a .augnew file.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
