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

All running applications using the NSS library must be restarted for 
this update to take effect.
