3. Description:

 

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 up[censored] 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 up[censored] 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)

 

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. (BZ#799885)

 

* 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 bug. (BZ#855022)

 

* 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. (BZ#799879)

 

* 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. (BZ#826752)

 

All Augeas users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues and add these

enhancements.
