DESCRIPTION:
NoGe has discovered some vulnerabilities in TalkBack, which can be
exploited by malicious people to disclose sensitive information or to
compromise a vulnerable system.

Input passed to the "config[comments_form_tpl]" parameter in
comments-display-tpl.php and the "language_file" parameter in
comments-display-tpl.php and
addons/separate-comments-mod/my-comments-display-tpl.php is not
properly verified before being used to include files. This can be
exploited to include arbitrary files from local or external
resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities are confirmed in version 2.2.7. Other versions
may also be affected.

SOLUTION:
