The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2012:0324 :
Updated libxml2 packages that fix one security issue are now available
for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.
The libxml2 library is a development toolbox providing the
implementation of various XML standards.
It was found that the hashing routine used by libxml2 arrays was
susceptible to predictable hash collisions. Sending a specially
crafted message to an XML service could result in longer processing
time, which could lead to a denial of service. To mitigate this issue,
randomization has been added to the hashing function to reduce the
chance of an attacker successfully causing intentional collisions.
All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop
must be restarted (log out, then log back in) for this update to take
