NVD Description

Note: Versions mentioned in the description apply only to the upstream augeas-libs package and not the augeas-libs package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

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.
