Liebe Kolleginnen und Kollegen,

soeben erreichte uns das nachfolgende Bulletin der HP SupportLine. Wir
geben diese Informationen unveraendert an Sie weiter.

Im original Advisory wurde die fuer eine Schwachstelle die falsche
CVE-ID angegeben. Die richtige ID ist CVE-2005-3352 anstatt
CVE-2006-3352.

CVE-2006-3747 - Buffer Overflow im Rewrite Modul mod_rewrite des Apache
Webservers

  Im Rewrite Modul mod_rewrite des Apache Webservers kann ein Buffer
  Overflow um ein Byte im Stack Segment (off-by-one) ausgeloest werden.
  Ein entfernter Angreifer kann diese Schwachstelle unter Umstaenden
  ausnutzen, um beliebige Befehle mit den Rechten des Webservers
  auszufuehren. Voraussetzungen sind, dass mod_rewrite verwendet wird,
  eine RewriteRule verwendet wird, wobei der Benutzer den Anfang der
  umgeschriebenen URL beeinflussen kann, und die Regel keine der Flags
  Forbidden (F), Gone (G) oder NoEscape (NE) beinhaltet.

CVE-2005-3352 - Cross Site Scripting Schwachstelle in Apache / mod_imap

  Es existiert eine Cross Site Scripting Schwachstelle im Modul mod_imap
  des Apache Webservers. In mod_imap wird die "Referer" Direktive
  innerhalb einer Image Map nicht korrekt ausgewertet. Ein entfernter
  Angreifer kann dadurch Skript-Code im Context der betroffenen Website
  ausfuehren. Fuer einen Angriff muss der Benutzer ein entsprechend
  manipuliertes HTML-Dokument mit einem Webbrowser anzeigen.

Betroffen sind die folgenden Software Pakete und Plattformen:

  VirtualVault 4.7
  VirtualVault 4.6
  VirtualVault 4.5
