Moderate: squirrelmail security update

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.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
