Synopsis:	Moderate: openssl security update
Issue date:	2010-03-25
CVE Names:	CVE-2009-0590 CVE-2009-2409 CVE-2009-3555

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 the CVE-2009-3555 flaw: http://kbase.redhat.com/faq/docs/DOC-20491

Dan Kaminsky found that browsers could accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser.
OpenSSL now disables the use of the MD2 algorithm inside signatures by
default. (CVE-2009-2409)

An input validation flaw was found in the handling of the BMPString and
UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex()
function. An attacker could use this flaw to create a specially-crafted
X.509 certificate that could cause applications using the affected 
function to crash when printing certificate contents. (CVE-2009-0590)

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