  Im Programm pstotext existiert eine Schwachstelle, die die fehlende
  Filterung von Shell-Metazeichen in Dateinamen betrifft, die als
  Argument in der Kommandozeile uebergeben werden. Ein Angreifer kann
  diese Schwachstelle mittels eines speziell konstruierten Dateinamenes
  ausnutzen, um beliebige Befehle mit den Rechten des Benutzers
  auszufuehren. Voraussetzung ist, dass das Programm pstotext von einem
  anderen Programm aufgerufen wird und der Angreifer den Dateinamen
  beinflussen kann.

Betroffen sind die folgenden Software Pakete und Plattformen:

  Paket pstotext in der stable Distribution (sarge) vor Version 1.9-1sarge2

Package        : pstotext
Vulnerability  : insecure file name quoting
Problem-Type   : local(remote)
Debian-specific: no
CVE ID         : CVE-2006-5869
Debian Bug     : 356988

Brian May discovered that pstotext, a utility to extract plain text from
Postscript and PDF files, performs insufficient quoting of file names,
which allows execution of arbitrary shell commands.

For the stable distribution (sarge) this problem has been fixed in
version 1.9-1sarge2. The build for the mipsel architecture is not yet
available due to technical problems with the build host.

For the upcoming stable distribution (etch) this problem has been
fixed in version 1.9-4.

For the unstable distribution (sid) this problem has been fixed in
version 1.9-4.

We recommend that you upgrade your pstotext package.
