The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2007:1095 :
Updated htdig packages that resolve a security issue are now available
for Red Hat Enterprise Linux 4 and 5.
This update has been rated as having moderate security impact by the
Red Hat Security Response Team.
The ht://Dig system is a complete World Wide Web indexing and
searching system for a small domain or intranet.
A cross-site scripting flaw was discovered in a htdig search page. An
attacker could construct a carefully crafted URL, which once visited
by an unsuspecting user, could cause a user's Web browser to execute
malicious script in the context of the visited htdig search Web page.
Users of htdig are advised to upgrade to these updated packages, which
contain backported patch to resolve this issue.
