Description Tomas Hoger 2013-02-28 21:05:40 UTC
It was discovered that IcedTea-Web browser plugin incorrectly used the same class loader for applets with the same codebase paths.  The default and commonly used codebase value is ".".  A malicious applet could use this flaw to gain information about or possibly manipulate other applets currently running in the browser.  This could possibly lead to malicious applet's code being executed as part of the other applet.
