Oracle Linux 5 : openssl097a (ELSA-2010-0164)

Medium Nessus Plugin ID 68018


The remote Oracle Linux host is missing a security update.


From Red Hat Security Advisory 2010:0164 :

Updated openssl097a packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

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.

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 flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746.

Refer to the following Knowledgebase article for additional details about this flaw:

All openssl097a users should upgrade to these updated packages, which contain a backported patch to resolve this issue. For the update to take effect, all services linked to the openssl097a library must be restarted, or the system rebooted.


Update the affected openssl097a package.
