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 .augsave file in a backup save action, a different vector than CVE-2012-0786.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
