1. Impact

The XSLT processor included with the Java Runtime Environment (JRE) may allow an untrusted applet to read data from another applet that is processed using the XSLT processor and may allow the untrusted applet to escalate privileges.

Sun acknowledges, with thanks, Marc Schoenefeld for bringing these issues to our attention.


2. Contributing Factors

These issues can occur in the following releases:

Windows Production Releases
SDK and JRE 1.4.2_04 or earlier

Solaris Operating Environment Production Releases
SDK and JRE 1.4.2_04 or earlier
SDK and JRE 1.4.1_07 or earlier
SDK and JRE 1.4.0_04 or earlier

Linux Production Releases

SDK and JRE 1.4.1_07 or earlier
SDK and JRE 1.4.0_04 or earlier

Note: SDK and JRE releases for Windows, Solaris and Linux prior to 1.4.0 are not affected by these issues.

To determine the release of a Java installation, run the "java" command with the "-fullversion" option:

$ java -fullversion
java full version "1.4.2_04-b03"
