Subject: kmMail XSS

kmMail XSS

* kmMail is an open-sourced web-based mail client, based on
Keftamail.

* kmMail version 1.0b has got a cross-site scripting bug when
viewing HTML e-mail messages. It filters out bad HTML elements,
but not good HTML elements with bad HTML attributes like this one:

<b onMouseOver="alert(document.location)">bolder</b>

* kmMail version 1.0b.1 doesn't have this problem.

* Therefore any kmMail users out there should upgrade.
