[RedHat] Schwachstelle in Mozilla SeaMonkey

Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.

MFSA 2011-34 – Kompromittierte SSL-Zertifikate betreffen mehrere
Produkte

Durch einen Einbruch bei der Certificate Authority DigiNotar wurden
diverse kompromittierte Zertifikate ausgestellt, u.a. ein
Wildcard-Zertifikat fuer *.google.com. Dies ermoeglicht einem entfernten
Angreifer einen eigenen Server unter der Adresse der kompromittierten
Zertifikate zu betreiben und einen Nutzer beispielsweise mittels
DNS-Manipulation auf diesen Server umzuleiten. So koennen Verbindungen
komplett abgehoert und manipuliert werden (Man-in-the-Middle-Angriff).
Es wurden bereits aktiv Man-in-the-Middle-Angriffe mit den betreffenden
Zertifikaten durchgefuehrt.

Betroffen sind die folgenden Software Pakete und Plattformen:

Paket seamonkey

Red Hat Enterprise Linux AS version 4 – i386, ia64, ppc, s390, s390x,
x86_64
Red Hat Enterprise Linux Desktop version 4 – i386, x86_64
Red Hat Enterprise Linux ES version 4 – i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 – i386, ia64, x86_64

Vom Hersteller werden ueberarbeitete Pakete zur Verfuegung gestellt.

Red Hat Security Advisory

Synopsis: Important: seamonkey security update
Advisory ID: RHSA-2011:1244-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1244.html
Issue date: 2011-08-31
=====================================================================

1. Summary:

Updated seamonkey packages that fix one security issue are now available
for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
important security impact.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 – i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 – i386, x86_64
Red Hat Enterprise Linux ES version 4 – i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 – i386, ia64, x86_64

3. Description:

SeaMonkey is an open source web browser, email and newsgroup client, IRC
chat client, and HTML editor.

It was found that a Certificate Authority (CA) issued a fraudulent HTTPS
certificate. This update renders any HTTPS certificates signed by that
CA as untrusted, except for a select few. The now untrusted certificates
that were issued before July 1, 2011 can be manually re-enabled and used
again at your own risk in SeaMonkey; however, affected certificates issued
after this date cannot be re-enabled or used. (BZ#734316)

All SeaMonkey users should upgrade to these updated packages, which correct
this issue. After installing the update, SeaMonkey must be restarted for
the changes to take effect.

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
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

734316 – Fraudulent certificates signed by DigiNotar CA certificate (MFSA 2011-34)
