tag_summary = "The remote server is running at least one instance of IMP whose version
number is between 3.0 and 3.2.1 inclusive.  Such versions are vulnerable
to several cross-scripting attacks whereby an attacker can cause a
victim to unknowingly run arbitrary Javascript code simply by reading an
HTML message from the attacker. 

Announcements of the vulnerabilities can be found at :

  - http://marc.theaimsgroup.com/?l=imp&m=105940167329471&w=2
  - http://marc.theaimsgroup.com/?l=imp&m=105981180431599&w=2
  - http://marc.theaimsgroup.com/?l=imp&m=105990362513789&w=2

Note : OpenVAS has determined the vulnerability exists on the target
simply by looking at the version number of IMP installed there.  If the
installation has already been patched, consider this a false positive.";

in the announcements to imp/lib/MIME/Viewer/html.php.";
