Description:
    There's an ongoing battle to further secure the HTML filter against
malicious HTML mail and the browsers that accept almost any malformed piece of HTML.

    This release contains fixes for the following:
    - HTML attachments containing "data:" URLs;
    - Internet Explorer in various versions accepts many permutations of HTML
    and JavaScript in many charsets. We now properly canonicalize the incoming
    HTML to us-ascii before applying further filters. IE only.
    - Request forgery through images. It was possible to include "images" in
    HTML mails which were in fact GET requests for the compose.php page sending
    mail. These images are now properly detected, and the compose form will only
    send mail through a POST request.
Affected Versions:
    1.4.0-1.4.9a

    Register_globals does not have to be on for this issue.
