DESCRIPTION:
Justin C. Klein Keane has discovered a weakness in the Views module
for Drupal, which can be exploited by malicious people to disclose
potentially sensitive information.

The weakness caused due an error in the
"views_ajax_autocomplete_user()" function in
modules/views/includes/ajax.inc, which does not properly check for
access permissions before querying for usernames. This can be
exploited to enumerate valid usernames.

The weakness is confirmed in version 6.x-2.11 and also reported in
version 5.x-1.8. Other versions may also be affected.

SOLUTION:
Edit the source code to implement proper access restrictions.
