DESCRIPTION:
Two vulnerabilities have been reported in Drupal, which can be
exploited by malicious users to conduct script insertion attacks and
by malicious people to conduct cross-site scripting attacks.

1) Certain input passed via the URL is not properly sanitised in the
Drupal error handler 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.

Successful exploitation of this vulnerability requires that on-screen
error display is enabled in admin/settings/error-reporting.

2) Input passed via the color scheme values (e.g. "palette[bg]",
"palette[text]", "palette[sideborders]", "palette[footer]", and
"palette[titleslogan]") to index.php (when "q" is set to
"admin/appearance/settings/bartik") when changing the color scheme is
not properly sanitised before being used in a style sheet. This can be
exploited to insert arbitrary CSS and script code, which will be
executed in a user's browser session in context of an affected site
when the malicious data is being viewed.

Successful exploitation of this vulnerability requires the
"Administer themes" privileges and the victim user is running a
browser which executes certain JavaScript statements from CSS files
(e.g. Internet Explorer 6).

The vulnerabilities are reported in version 6.20. Prior versions may
also be affected.

SOLUTION:
Update to version 6.21 or later.

1) The vendor credits Heine Deelstra, Drupal security team.
2) Kasper Lindgaard, Secunia Research.
