Detailed vulnerability description
The vulnerability allows a local non-authenticated attacker to read and manipulate data.
The transform_save function in transform.c in Augeas 1.0.0 through 1.1.0 does not properly calculate the permission values when the umask contains a "7," which causes world-writable permissions to be used for new files and allows local users to modify the files via unspecified vectors.
