Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

CVE-2009-3555 TLS: MITM attacks via session renegotiation

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.
(CVE-2009-3555)

Refer to the following Knowledgebase article for additional details
about this flaw: http://kbase.redhat.com/faq/docs/DOC-20491

For the update to take effect, all services linked to the openssl097a
library must be restarted, or the system rebooted.
