The remote Red Hat host is missing a security update.
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: http://kbase.redhat.com/faq/docs/DOC-20491
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.
