[RedHat] Schwachstelle in der Bibliothek libvorbis vor Version r16182 - RHSA-2009:1219-01



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Liebe Kolleginnen und Kollegen,

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


Vorbis ist ein Audiocodec. Die Bibliothek libvorbis dient zum Lesen und
Schreiben entsprechender Datenstroeme bzw. deren Dateiformat Ogg Vorbis
(Endung .ogg). Sie wird von verschiedenen Anwendungen benutzt, u.a.
Mozilla Firefox.


CVE-2009-2663 - Null Pointer Referenzierung in der libvorbis Funktion
vorbis_book_decodevv_add()

  In der Funktion vorbis_book_decodevv_add() der Bibliothek libvorbis
  kommt es beim Parsen eines entsprechend aufgebauten Vorbis Audio
  Streams zur Referenzierung eines Null Pointers. Ein Angreifer kann
  diese Schwachstelle dazu ausnutzen, beliebigen Code mit den Rechten
  des Benutzers der Anwendung auszufuehren die den Datenstrom bzw. die
  .ogg Datei liest.

Betroffen sind die folgenden Software Pakete und Plattformen:

  Paket libvorbis

3. Description:

The libvorbis packages contain runtime libraries for use in programs that
support Ogg Vorbis. Ogg Vorbis is a fully open, non-proprietary, patent-and
royalty-free, general-purpose compressed audio format.

An insufficient input validation flaw was found in the way libvorbis
processes the codec file headers (static mode headers and encoding books)
of the Ogg Vorbis audio file format (Ogg). A remote attacker could provide
a specially-crafted Ogg file that would cause a denial of service (memory
corruption and application crash) or, potentially, execute arbitrary code
with the privileges of an application using the libvorbis library when
opened by a victim. (CVE-2009-2663)

Users of libvorbis should upgrade to these updated packages, which contain
a backported patch to correct this issue. The desktop must be restarted
(log out, then log back in) for this update to take effect.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via 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/):

516259 - CVE-2009-2663 libvorbis: Improper codec headers processing (DoS, ACE)
