    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 < 1.4.2.08 >= 1.4.2.08
      2 dev-java/sun-jre-bin < 1.4.2.08 >= 1.4.2.08
      3 dev-java/blackdown-jdk < 1.4.2.02 >= 1.4.2.02
      4 dev-java/blackdown-jre < 1.4.2.02 >= 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 ">=dev-java/sun-jdk-1.4.2.08"

    All Sun JRE users should upgrade to the latest version:

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

    All Blackdown JRE users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=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.
