Category
Security

Release Phase
Resolved

Product
Java 2 Platform, Standard Edition

Bug Id
6387628, 6393286

Date of Resolved Release
19-DEC-2006

Impact

Two vulnerabilities related to serialization in the Java Runtime Environment may independently allow an untrusted applet or application to elevate its privileges.

Sun acknowledges, with thanks, Tom Hawtin, for bringing these issues to our attention.


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

Note: SDK and JRE 1.3.x are not affected.

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.


Symptoms

There are no reliable symptoms that would indicate the described issue has been exploited.


Workaround

There is no workaround.
