The remote Oracle Linux host is missing a security update.
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
scripting attacks by sending an e-mail viewed by a user within
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.
Users of SquirrelMail should upgrade to this erratum package, which
contains a backported patch to correct these issues.
