JRE Multiple Java Plug-in Vulnerabilities



Multiple vulnerabilities affect the Java Plug-in in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier, 6 Update 12 and earlier, 1.4.2_19 and earlier as well as 1.3.1_24 and earlier.

  • A flaw in deserializing applets may allow untrusted applets to escalate privileges and grant itself permissions to read, write and execute local files and applications accessible to the user.
  • The Java Plug-in allows javascript code loaded from the localhost to connect to any port on the system. This can be leveraged with XSS vulnerabilities to access other applications on the system.
  • The Java Plug-in allows a trusted applet to be launched on an earlier version of the Java Runtime Environment. This could allow a downloaded applet to exploit vulnerabilities previously patched.
  • The Java Plug-in incorrectly parses crossdomain.xml, allowing an untrusted applet to connect to any site that provides a crossdomain.xml file instead of the sites that allow the domain the applet is running on.
  • The Java Plug-in may allow a signed applet to obscure the contents of the security dialog and therefore trick the user into trusting the applet.
