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