Red Hat Security Advisory 2014-0044-01 - Augeas is a utility for editing configuration. Augeas parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native configuration files. Augeas also uses "lenses" as basic building blocks for establishing the mapping from files into the Augeas tree and back. A flaw was found in the way Augeas handled certain umask settings when creating new configuration files. This flaw could result in configuration files being created as world writable, allowing unprivileged local users to modify their content.
