The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2008:0884 :
Updated libxml2 packages that fix a security issue are now available
for Red Hat Enterprise Linux 3, 4, and 5.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
The libxml2 packages provide a library that allows you to manipulate
XML files. It includes support to read, modify, and write XML and HTML
A heap-based buffer overflow flaw was found in the way libxml2 handled
long XML entity names. If an application linked against libxml2
processed untrusted malformed XML content, it could cause the
application to crash or, possibly, execute arbitrary code.
All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to resolve this issue.
