The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2014:0594 :
Updated gnutls packages that fix multiple security issues are now
available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
Important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.
The GnuTLS library provides support for cryptographic algorithms and
for protocols such as Transport Layer Security (TLS). The gnutls
packages also include the libtasn1 library, which provides Abstract
Syntax Notation One (ASN.1) parsing and structures management, and
Distinguished Encoding Rules (DER) encoding and decoding functions.
A flaw was found in the way GnuTLS parsed session IDs from ServerHello
messages of the TLS/SSL handshake. A malicious server could use this
flaw to send an excessively long session ID value, which would trigger
a buffer overflow in a connecting TLS/SSL client application using
GnuTLS, causing the client application to crash or, possibly, execute
arbitrary code. (CVE-2014-3466)
It was discovered that the asn1_get_bit_der() function of the libtasn1
library incorrectly reported the length of ASN.1-encoded data.
Specially crafted ASN.1 input could cause an application using
libtasn1 to perform an out-of-bounds access operation, causing the
application to crash or, possibly, execute arbitrary code.
Multiple incorrect buffer boundary check issues were discovered in
libtasn1. Specially crafted ASN.1 input could cause an application
using libtasn1 to crash. (CVE-2014-3467)
Multiple NULL pointer dereference flaws were found in libtasn1's
asn1_read_value() function. Specially crafted ASN.1 input could cause
an application using libtasn1 to crash, if the application used the
aforementioned function in a certain way. (CVE-2014-3469)
Red Hat would like to thank GnuTLS upstream for reporting these
issues. Upstream acknowledges Joonas Kuorilehto of Codenomicon as the
original reporter of CVE-2014-3466.
Users of GnuTLS are advised to upgrade to these updated packages,
which correct these issues. For the update to take effect, all
applications linked to the GnuTLS or libtasn1 library must be
