Date of Resolved Release
Multiple Security Vulnerabilities in Java Plug-in May Allow Privileges to be Escalated
CR 6646860: A security vulnerability in the Java Plug-in with deserializing applets may allow an untrusted applet to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet.
CR 6798948: A security vulnerability in the Java Plug-in with parsing crossdomain.xml files may allow an untrusted applet to connect to any site that provides a crossdomain.xml file instead of sites that allow the domain that the applet is running on.
CR 6782871: A security vulnerability in the Java Plug-in may allow a signed applet to obscure the contents of the security dialog and thereby trick a user into trusting the applet.
Sun acknowledges with thanks: Gregory Fleischer (for CR 6798948) and Michael Schierl (for CR 6782871).
