Synopsis
=======

Sun's and Blackdown's JDK or JRE may allow untrusted applets to elevate their privileges.

Background
=========

Sun and Blackdown both provide implementations of the Java Development Kit (JDK) and Java Runtime Environment (JRE).

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/sun-jdk lt; 1.4.2.08 gt;= 1.4.2.08
2 dev-java/sun-jre-bin lt; 1.4.2.08 gt;= 1.4.2.08
3 dev-java/blackdown-jdk lt; 1.4.2.02 gt;= 1.4.2.02
4 dev-java/blackdown-jre lt; 1.4.2.02 gt;= 1.4.2.02
-------------------------------------------------------------------
4 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
==========

Both Sun's and Blackdown's JDK and JRE may allow untrusted applets to elevate privileges.

Impact
=====

A remote attacker could embed a malicious Java applet in a web page and entice a victim to view it. This applet can then bypass security restrictions and execute any command or access any file with the rights of the user running the web browser.

Workaround
=========

There are no known workarounds at this time.

Resolution
=========

All Sun JDK users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-java/sun-jdk-1.4.2.08"

All Sun JRE users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-java/sun-jre-bin-1.4.2.08"

All Blackdown JDK users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-java/blackdown-jdk-1.4.2.02"

All Blackdown JRE users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-java/blackdown-jre-1.4.2.02"

Note to SPARC users: There is no stable secure Blackdown Java for the SPARC architecture. Affected users should remove the package until a SPARC package is released.
