Liebe Kolleginnen und Kollegen,
soeben erreichte uns das nachfolgende Bulletin des SUN Customer Warning
System. Wir geben diese Informationen unveraendert an Sie weiter.
Sun Bug Id# 6571539 - Schwachstelle in der Java Runtime Environment
Virtual Machine
Eine nicht naeher beschriebene Schwachstelle in der Virtual Machine
des Java Runtime Environment erlaubt es einem Applet sich selbst die
Berechtigung zu geben, Dateien ausserhalb der Sandbox zu lesen, zu
schreiben und Programme auszufuehren. Ein entfernter Angreifer kann
dadurch beliebige Befehle mit den Rechten des Benutzers ausfuehren,
wenn dieser ein entsprechendes Applet des Angreifers laedt.
Betroffen sind die folgenden Software Pakete und Plattformen:
JDK und JRE:
* JDK und JRE 6 vor Update 3
* JDK und JRE 5.0 vor Update 13
* SDK und JRE vor 1.4.2_16
* SDK und JRE vor 1.3.1_21
JDK 6 Update 3 fuer Solaris:
* Java SE 6 Update 3 (Patch 125136-04)
* Java SE 6 Update 3 (Patch 125137-04 (64bit))
* Java SE 6_x86 Update 3 (Patch 125138-04)
* Java SE 6_x86 Update 3 (Patch 125139-04 (64bit))
JDK 5.0 Update 13 fuer Solaris:
* J2SE 5.0 Update 13 (Patch 118666-14)
* J2SE 5.0 Update 13 (Patch 118667-14 (64bit))

Sun(sm) Alert Notification
* Sun Alert ID: 103112
* Synopsis: Vulnerability in Java Runtime Environment Virtual Machine May
Allow Untrusted Application or Applet to Elevate Privileges
* Category: Security
* Product: Java 2 Platform, Standard Edition
* BugIDs: 6571539
* Avoidance: Patch, Upgrade
* State: Resolved
* Date Released: 22-Oct-2007
* Date Closed: 22-Oct-2007
* Date Modified:
1. Impact
A vulnerability in the Virtual Machine of the Java Runtime Environment may
allow an untrusted applet to elevate its privileges. For example, an applet
may grant itself permissions to read and write local files or execute local
applications that are accessible to the user running the untrusted applet.
Sun acknowledges with thanks, Azul Systems, Inc., for bringing this issue to
our attention.
2. Contributing Factors
This issue can occur in the following releases (for Windows, Solaris, and
Linux):
* JDK and JRE 6 Update 2 and earlier
* JDK and JRE 5.0 Update 12 and earlier
* SDK and JRE 1.4.2_15 and earlier
* SDK and JRE 1.3.1_20 and earlier
To determine the default version of the JRE that Internet Explorer uses:
1. Click "Tools" in the Menu Bar at the top of the browser
2. Select "Sun Java Console"
3. The first two lines in the console display the version of Java Plug-in
and JRE that Internet Explorer uses.
To determine the default version of the JRE that Mozilla or Firefox browsers
use, visit the URL "about:plugins".
The browser will display a page called "Installed plug-ins" which lists the
version of the Java Plug-in:
Java(TM) Plug-in 1.5.0_11-b03
The above example indicates that the version of the JRE that the browser
uses is 1.5.0_11.
3. Symptoms
There are no predictable symptoms that would indicate the issue described is
being exploited.
