Description Murray McAllister 2013-09-23 11:45:36 UTC 
LiveConnect provides a gateway between the JavaScript engine in the web browser and Java applets. An insecure temporary file use flaw was found in the LiveConnect implementation in the IcedTea-Web browser plug-in. A malicious, local user could possibly use this flaw to inject or read the communication between a Java applet and web browser of a different user's session.
