Multiple cross-site scripting (XSS) vulnerabilities in the HTML filter in SquirrelMail 1.4.0 through 1.4.9a allow remote attackers to inject arbitrary web script or HTML via the (1) data: URI in an HTML e-mail attachment or (2) various non-ASCII character sets that are not properly filtered when viewed with Microsoft Internet Explorer.

From Red Hat Security Advisory 2007:0358 :

A new squirrelmail package that fixes security issues is now available for Red Hat Enterprise Linux 3, 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

SquirrelMail is a standards-based webmail package written in PHP4.

Several HTML filtering bugs were discovered in SquirrelMail. An attacker could inject arbitrary JavaScript leading to cross-site scripting attacks by sending an e-mail viewed by a user within SquirrelMail. (CVE-2007-1262)

Squirrelmail did not sufficiently check arguments to IMG tags in HTML e-mail messages. This could be exploited by an attacker by sending arbitrary e-mail messages on behalf of a squirrelmail user tricked into opening a maliciously crafted HTML e-mail message.
(CVE-2007-2589)

Users of SquirrelMail should upgrade to this erratum package, which contains a backported patch to correct these issues.

It was discovered that the webmail package Squirrelmail performs insufficient sanitising inside the HTML filter, which allows the injection of arbitrary web script code during the display of HTML email messages.
