<title>Sun and Blackdown Java: Applet privilege escalation</title>
<synopsis>
The Java plug-in security in Sun and Blackdown Java environments can be
bypassed to access arbitrary packages, allowing untrusted Java applets to
perform unrestricted actions on the host system.

<background>
<p>
Sun and Blackdown both provide implementations of Java Development Kits
(JDK) and Java Runtime Environments (JRE). All these implementations
provide a Java plug-in that can be used to execute Java applets in a
restricted environment for web browsers.
</p>
</background>
<description>
<p>
All Java plug-ins are subject to a vulnerability allowing unrestricted
Java package access.
</p>
</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
As a workaround you could disable Java applets on your web browser.
</p>
</workaround>
<resolution>
<p>
All Sun JDK users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.06"</code>
<p>
All Sun JRE users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.06"</code>
<p>
All Blackdown JDK users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jdk-1.4.2.01"</code>
<p>
All Blackdown JRE users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jre-1.4.2.01"</code>
<p>
Note: You should unmerge all vulnerable versions to be fully protected.
