Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgende Warnung des Debian-Teams. Wir geben
diese Informationen unveraendert an Sie weiter.

Mon ist ein Programm, welches zum Ueberwachen der von einem Server
angebotenen Dienste genutzt werden kann.

CVE-2008-4477 - Schwachstelle in mon ermoeglicht Symlink Angriffe

  Das im Monitoring Programm mon enthaltene Script 'test.alert' erzeugt
  temporaere Dateien auf unsichere Weise. Ein lokaler Angreifer kann
  eine temporaere Datei durch einen Symlink ersetzen, was dazu fuehrt,
  dass mon die verlinkte Datei mit temporaeren Daten ueberschreibt.

Betroffen sind die folgenden Software Pakete und Plattformen:

  Paket mon in der stable Distribution (etch), Version 0.99.2-9+etch2
  Paket mon in der unstable (sid) und testing (lenny) Distribution,
  Version 0.99.2-13

  Stable Distribution (etch)
  Unstable Distribution (sid)
  Testing Distribution (lenny)

Vom Hersteller werden ueberarbeitete Pakete zur Verfuegung gestellt.

Package        : mon
Vulnerability  : insecure temporary files
Problem type   : local
Debian-specific: no
CVE Id(s)      : CVE-2008-4477
Debian Bug     : 496398

Dmitry E. Oboukhov discovered that the test.alert script used in one of the 
alert functions in mon, a system to monitor hosts or services and alert 
about problems, creates temporary files insecurely, which may lead to a local 
denial of service through symlink attacks.

For the stable distribution (etch), this problem has been fixed in
version 0.99.2-9+etch2.

For the testing (lenny) and unstable distribution (sid), this problem has
been fixed in version 0.99.2-13.

We recommend that you upgrade your mon package.
