Sun(sm) Alert Notification
     * Sun Alert ID: 102729
     * Synopsis: Security Vulnerabilities in the Java Runtime Environment
       may Allow Untrusted Applets to Elevate Privileges and Execute
       Arbitrary Code
     * Category: Security
     * Product: Java 2 Platform, Standard Edition
     * BugIDs: 6363511, 6363512
     * Avoidance: Patch, Upgrade
     * State: Resolved
     * Date Released: 19-Dec-2006
     * Date Closed: 19-Dec-2006
     * Date Modified: 

1. Impact

   Two buffer overflow vulnerabilities in the Java Runtime Environment
   may independently 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, Chris Evans, for bringing these issues
   to our attention.

2. Contributing Factors

   These issues can occur in the following releases (for Windows,
   Solaris, and Linux):
     * JDK and JRE 5.0 Update 7 and earlier
     * SDK and JRE 1.4.2_12 and earlier
     * SDK and JRE 1.3.1_18 and earlier

   To determine the default version of the JRE on a system for Solaris
   and Linux, the following command can be run:
    % java -version

   Note: The above command only determines the default version. Other
   versions may also be installed on the system.

   To determine the default version of the JRE on a system for Windows:
    1. Click "Start"
    2. Select "Run"
    3. Type "cmd" (starts a command-line)
    4. At the prompt, type "java -version"

   Note: The above command only determines the default version. Other
   versions may also be installed on the system.

3. Symptoms

   There are no reliable symptoms that would indicate the described
   issues have been exploited. 

4. Relief/Workaround

   There is no workaround.

5. Resolution

   These issues are addressed in the following releases (for Windows,
   Solaris, and Linux):
     * JDK and JRE 5.0 Update 8 or later
     * SDK and JRE 1.4.2_13 or later
     * SDK and JRE 1.3.1_19 or later
