Liebe Kolleginnen und Kollegen,

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

CVE-2006-5864 - Buffer Overflow in ps_gettext Funktion in GNU gv

  In der ps_gettext Funktion (ps.c) in GNU gv werden Kommentare in
  Postscript-Datein in einen Buffer mit fester Groesse kopiert. Die
  Folge davon ist ein Buffer Overflow im Stack Segment. Ein entfernter
  Angreifer kann diese Schwachstelle ausnutzen, um beliebige Befehle mit
  den Rechten des Benutzers auszufuehren, falls dieser ein
  Postscript-Dokument des Angreifers mit gv oeffnet. Ein Exploit zur
  Ausnutzung der Schwachstelle unter Linux ist bereits oeffentlich
  verfuegbar.

Betroffen sind die folgenden Software Pakete und Plattformen:

  Paket gv

  Mandriva 2006.0
  Mandriva 2007.0
  Mandriva Corporate 3.0
  Mandriva Corporate 4.0
