-----BEGIN PGP SIGNED MESSAGE-----

Liebe Kolleginnen und Kollegen,

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

CVE-2008-3916 - Schwachstelle im Editor GNU ed vor Version 1.0

  Im Editor GNU ed kann mit einem sehr langen Dateinamen, der auf der
  Kommandozeile angegeben wird, ein Heap Overflow in der Funktion
  strip_escapes() ausgeloest werden. Ein Angreifer kann beliebige
  Befehle mit den Rechten des Benutzers ausfuehren, wenn dieser eine
  Datei mit entsprechend manipulierten Namen oeffnet. In der Regel
  sollte der Dateiname den Benutzer allerdings stutzig machen.

Betroffen sind die folgenden Software Pakete und Plattformen:

3. Description:

ed is a line-oriented text editor, used to create, display, and modify
text files (both interactively and via shell scripts).

A heap-based buffer overflow was discovered in the way ed, the GNU line
editor, processed long file names. An attacker could create a file with a
specially-crafted name that could possibly execute an arbitrary code when
opened in the ed editor. (CVE-2008-3916)

Users of ed should upgrade to this updated package, which contains
a backported patch to resolve this issue.

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
