The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2008:0982 :
Updated gnutls packages that fix a security issue are now available
for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the
Red Hat Security Response Team.
The GnuTLS library provides support for cryptographic algorithms and
for protocols such as Transport Layer Security (TLS).
Martin von Gagern discovered a flaw in the way GnuTLS verified
certificate chains provided by a server. A malicious server could use
this flaw to spoof its identity by tricking client applications using
the GnuTLS library to trust invalid certificates. (CVE-2008-4989)
Users of GnuTLS are advised to upgrade to these updated packages,
which contain a backported patch that corrects this issue.
