Vulnerability Assessment Details

[GLSA-200602-07] Sun JDK/JRE: Applet privilege escalation

Vulnerability Assessment Summary
Sun JDK/JRE: Applet privilege escalation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200602-07
(Sun JDK/JRE: Applet privilege escalation)

Applets executed using JRE or JDK can use "reflection" APIs
functions to elevate its rights beyond the sandbox restrictions.
Adam Gowdiak discovered five vulnerabilities that use this method for
privilege escalation. Two more vulnerabilities were discovered by the
vendor. Peter Csepely discovered that Web Start Java applications also
can an escalate their rights.

Impact

A malicious Java applet can bypass Java sandbox restrictions and
hence access local files, connect to arbitrary network locations and
execute arbitrary code on the user's machine. Java Web Start
applications are affected likewise.

Workaround

Select another Java implementation using java-config.
