[GLSA-200601-10] Sun and Blackdown Java: Applet privilege escalation

Vulnerability Assessment Summary
Sun and Blackdown Java: Applet privilege escalation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200601-10
(Sun and Blackdown Java: Applet privilege escalation)

Adam Gowdiak discovered multiple vulnerabilities in the Java
Runtime Environment's Reflection APIs that may permit untrusted applets
to elevate rights.

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.

Solution:
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.
