Liebe Kolleginnen und Kollegen,
soeben erreichte uns nachfolgendes Advisory von Mandriva Security. Wir
geben diese Informationen unveraendert an Sie weiter.
Mit diesem Update auf Version 3.12.6 verwenden die Network Security
Services (NSS) eine RFC 5746 konforme Version der TLS Renegotiation
Indication Extension, welche die Designschwaeche behebt. Fruehere
Updates haben die Schwachstelle dadurch behoben, dass die TLS
Renegotiation vollstaendig deaktiviert wurde.
CVE-2009-3555 – Designschwaeche im SSLv3/TSLv1 Protokoll bei der
Renegotiation
Bei der Neuaushandlung von Parametern in einer SSL oder TLS Session
(Renegotiation) wird das Client Zertifikat geprueft. Allerdings ist es
aufgrund einer Schwachstelle im TLS-Protokoll unter Umstaenden moeglich,
dass vorher beliebige Daten in die TLS-Session eingeschleust werden. Dies
ermoeglicht Man-in-the-Middle Angriffe auf die TLS-Session. Beim HTTPS
Protokoll kann ein Angreifer so den HTTP-Request des Benutzers faelschen.
Dies kann ein Angreifer dazu ausnutzen, um an vertrauliche Daten zu
gelangen, Operationen mit den Rechten des Benutzers auf dem Server
auszufuehren, dem Benutzer falsche Informationen anzuzeigen.
Diese Schwachstelle wird bereits aktiv von Angreifern ausgenutzt.
Betroffen sind die folgenden Software Pakete und Plattformen:

_______________________________________________________________________
Package : nss
Date : April 6, 2010
Affected: 2008.0, 2009.0, 2009.1, 2010.0, Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
A vulnerability has been found and corrected in nss:
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as
used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl
in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l,
GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS)
3.12.4 and earlier, and other products, does not properly associate
renegotiation handshakes with an existing connection, which allows
man-in-the-middle attackers to insert data into HTTPS sessions,
and possibly other types of sessions protected by TLS or SSL, by
sending an unauthenticated request that is processed retroactively
by a server in a post-renegotiation context, related to a plaintext
injection attack, aka the Project Mogul issue (CVE-2009-3555).
Additionally the NSPR package has been upgraded to 4.8.4 that brings
numerous upstream fixes.
Packages for 2008.0 are provided for Corporate Desktop 2008.0
customers.
This update provides the latest versions of NSS and NSPR libraries
and for which NSS is not vulnerable to this attack.
