jdk/jre -- Applet Caching May Allow Network Access Restrictions to be Circumvented

SUN reports:

A vulnerability in the Java Runtime Environment (JRE) with applet
caching may allow an untrusted applet that is downloaded from a
malicious website to make network connections to network services
on machines other than the one that the applet was downloaded from.
This may allow network resources (such as web pages) and
vulnerabilities (that exist on these network services) which are not
otherwise normally accessible to be accessed or exploited.
