The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2010:0977 :
Updated openssl packages that fix three security issues are now
available for Red Hat Enterprise Linux 4.
The Red Hat Security Response Team has rated this update as having
moderate 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.
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL
v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.
A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server
code. A remote attacker could possibly use this flaw to change the
ciphersuite associated with a cached session stored on the server, if
the server enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option,
possibly forcing the client to use a weaker ciphersuite after resuming
the session. (CVE-2010-4180, CVE-2008-7270)
Note: With this update, setting the
SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option has no effect and this
bug workaround can no longer be enabled.
It was discovered that OpenSSL did not always check the return value
of the bn_wexpand() function. An attacker able to trigger a memory
allocation failure in that function could possibly crash an
application using the OpenSSL library and its UBSEC hardware engine
All OpenSSL users should upgrade to these updated packages, which
contain backported patches to resolve these issues. For the update to
take effect, all services linked to the OpenSSL library must be
restarted, or the system rebooted.
