Multiple race conditions were discovered in augeas when saving configuration files which expose it to symlink attacks. Write access to the directory where the configuration file is located is required by the attacker.

Updated augeas packages fix security vulnerabilities :

Multiple flaws were found in the way Augeas handled configuration files when updating them. An application using Augeas to update configuration files in a directory that is writable to by a different user (for example, an application running as root that is updating files in a directory owned by a non-root service user) could have been tricked into overwriting arbitrary files or leaking information via a symbolic link or mount point attack (CVE-2012-0786, CVE-2012-0787).

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).

From Red Hat Security Advisory 2014:0044 :

Updated augeas packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

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.
