DESCRIPTION:
Two vulnerabilities have been reported in the CKEditor and FCKeditor
modules for Drupal, which can be exploited by malicious users to
compromise a vulnerable system and by malicious people to conduct
cross-site scripting attacks.

1) Certain input when editing content is not properly sanitised
before being returned to the user. This can be exploited to execute
arbitrary HTML and script code in a user's browser session in context
of an affected site.

2) Certain unspecified input is not properly sanitised before being
used. This can be exploited to execute arbitrary PHP code.

Note: Successful exploitation of this vulnerability for FCKeditor
version 6.x requires the "access fckeditor" permission and for
CKEditor version 6.x requires the "access ckeditor" permission.

The vulnerabilities are reported in the FCKeditor module versions
6.x-2.x prior to 6.x-2.3 and the CKEditor module versions 6.x-1.x
prior to 6.x-1.9 and 7.x-1.x prior to 7.x-1.7.

SOLUTION:
Update to a fixed version.
