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.
4. Relief/Workaround
There is no workaround for this issue. Please see the Resolution
