Liebe Kolleginnen und Kollegen,
soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.
CVE-2009-3245 / Bugtraq 38562 – Schwachstelle in der OpenSSL-Suite
An mehreren Stellen in der OpenSSL-Suite wird die Funktion
bn_wexpand() aufgerufen, die den Speicherbereich, den eine grosse Zahl
(BIGNUM) beinhaltet, zu erweitern. Dabei wird aber nicht ueberprueft, ob
diese Erweiterung erfolgreich war, wozu es zu einem Buffer-Overflow
kommen kann.
Diese Schwachstelle kann von einem entfernten Angreifer fuer einen
Denial-of-Service-Angriff benutzt werden und eventuell zur Ausfuehrung
von beliebigem Code mit Rechten der Anwendung, die die Bibliothek
verwendet.
Betroffen sind die folgenden Software Pakete und Plattformen:
Paket openssl096b
Red Hat Desktop version 3 – i386, x86_64
Red Hat Enterprise Linux AS version 3 – i386, ia64, ppc, s390, s390x,

3. Description:
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.
It was discovered that OpenSSL did not always check the return value of the
bn_wexpand() function. An attacker able to trigger a memory allocation
failure in that function could cause an application using the OpenSSL
library to crash or, possibly, execute arbitrary code. (CVE-2009-3245)
All openssl096b users should upgrade to these updated packages, which
contain a backported patch to resolve this issue. For the update to take
effect, all programs using the openssl096b library must be restarted.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):
570924 – CVE-2009-3245 openssl: missing bn_wexpand return value checks
