Multiple vulnerabilities in the Sun Java Reflection API may allow an untrusted Java applet to bypass security restrictions and execute arbitrary code.
The Sun Java Reflection API allows Java classes to determine information about other Java classes, such as public methods. There are three, unspecified vulnerabilities in the Reflection API that may allow a Java applet to bypass Java applet security restrictions. Once the security restrictions are bypassed, the malicious applet may be able to access and manipulate system resources.
For more information on the Java security model see Sun's Java documentation, particularly the Applet Security FAQ. For more information regarding these vulnerabilities and how to correct them, please refer to Sun Alert 102003.
By convincing a user to run a Java applet, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user running the applet. Web browsers with Java support may run applets from untrusted web sites.
J2SE 5.0 is available for download at http://java.sun.com/j2se/1.5.0/download.jsp
and at http://java.com
Note: It is recommended that affected versions be removed from your system. For more information, please see the installation notes on the respective java.sun.com download pages.
Do not access Java Applets from untrusted sources
Java applets are commonly executed within a web browser. Disabling Java within the web browser may prevent an attacker from delivering a malicious applet to a vulnerable system.
These vulnerabilities were reported by Sun Microsystems. Sun credits Adam Gowdiak, with providing information regarding these issues.
