DESCRIPTION:
Nenad Vijatov has discovered a vulnerability in MDaemon, which can be
exploited by malicious people to conduct script insertion attacks.

Input passed via "<IMG>" HTML tags in emails is not properly
sanitised before being displayed. This can be exploited to insert
arbitrary HTML and script code via a specially crafted email, which
is executed in a user's browser session in context of an affected
site when the email is viewed.

The vulnerability is confirmed in version 10.0.2 with Internet
Explorer 7. Other versions may also be affected.

SOLUTION:
Do not view untrusted emails using the MDaemon WorldClient.
