| Description: | Augeas is a utility for editing configuration. Augeas parses configurationfiles in their native formats and transforms them into a tree.Configuration changes are made by manipulating this tree and saving it backinto native configuration files. Augeas also uses "lenses" as basicbuilding blocks for establishing the mapping from files into the Augeastree and back.Multiple flaws were found in the way Augeas handled configuration fileswhen updating them. An application using Augeas to update configurationfiles 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 ownedby a non-root service user) could have been tricked into overwritingarbitrary files or leaking information via a symbolic link or mount pointattack. (CVE-2012-0786, CVE-2012-0787)The augeas package has been upgraded to upstream version 1.0.0, whichprovides 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 wasunable to parse the file with the XML lens. An upstream patch has beenprovided ensuring that single quotes are handled as valid characters andparsing 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 toproperly 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 lineendings. The XML lens has been fixed to handle files with CRLF lineendings, thus fixing this bug. (BZ#799879)* Previously, Augeas was unable to parse modprobe.conf files with spacesaround "=" characters in option directives. The modprobe lens has beenupdated and parsing no longer fails. (BZ#826752)All Augeas users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues and add theseenhancements. |
