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           < 1.4.2.09                 >= 1.4.2.09
  2  dev-java/sun-jre-bin       < 1.4.2.09                 >= 1.4.2.09
  3  dev-java/blackdown-jdk     < 1.4.2.03                 >= 1.4.2.03
  4  dev-java/blackdown-jre     < 1.4.2.03                 >= 1.4.2.03
    -------------------------------------------------------------------
     4 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

Adam Gowdiak discovered multiple vulnerabilities in the Java Runtime
Environment's Reflection APIs that 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 ">=dev-java/sun-jdk-1.4.2.09"

All Sun JRE users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.09"

All Blackdown JDK users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-java/blackdown-jdk-1.4.2.03"

All Blackdown JRE users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-java/blackdown-jre-1.4.2.03"

Note to SPARC and PPC users: There is no stable secure Blackdown Java
for the SPARC or PPC architectures. Affected users on the PPC
architecture should consider switching to the IBM Java packages
(ibm-jdk-bin and ibm-jre-bin). Affected users on the SPARC should
remove the package until a SPARC package is released.
