Summary

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. (CVE-2013-6412)
This issue was discovered by the Red Hat Security Response Team.
All augeas users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using augeas must be restarted for the update to take effect.
