Low: augeas security, bug fix, and enhancement update
Security Advisory: Low
Updated augeas packages that fix two security issues, several bugs, and add
various enhancements are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low
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.
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)
The augeas package has been upgraded to upstream version 1.0.0, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#817753)

All Augeas users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues and add these
enhancements.
