The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2013:1457 :
An updated libgcrypt package that fixes one security issue is 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 libgcrypt library provides general-purpose implementations of
various cryptographic algorithms.
It was found that GnuPG was vulnerable to the Yarom/Falkner
flush+reload cache side-channel attack on the RSA secret exponent. An
attacker able to execute a process on the logical CPU that shared the
L3 cache with the GnuPG process (such as a different local user or a
user of a KVM guest running on the same host with the kernel same-page
merging functionality enabled) could possibly use this flaw to obtain
portions of the RSA secret key. (CVE-2013-4242)
All libgcrypt users are advised to upgrade to this updated package,
which contains a backported patch to correct this issue.
