Synopsis: Low: augeas security, bug fix, and enhancement update
Advisory ID: SLSA-2013:1537-2
Issue Date: 2013-11-21
CVE Numbers: CVE-2012-0786
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.
This update also fixes the following bugs:
* Previously, when single quotes were used in an XML attribute, Augeas was
unable to parse the file with the XML lens. An upstream patch has been
provided ensuring that single quotes are handled as valid characters and
parsing no longer fails.
* Prior to this update, Augeas was unable to set up the
“require_ssl_reuse” option in the vsftpd.conf file. The updated patch
fixes the vsftpd lens to properly recognize this option, thus fixing this
* Previously, the XML lens did not support non-Unix line endings.
Consequently, Augeas was unable to load any files containing such line
endings. The XML lens has been fixed to handle files with CRLF line
endings, thus fixing this bug.
* Previously, Augeas was unable to parse modprobe.conf files with spaces
around “=” characters in option directives. The modprobe lens has been
updated and parsing no longer fails.
