Id Description
11751 Java Virtual Machine sun.applet.AppletClassLoader loadClass Method Arbitrary ...

The Sun Java Virtual Machine, present in their JDK & SDK products, contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when a package is loaded into the JVM using a "/" instead of a "." for the package name separator. This causes the package access checks to be bypassed, allowing users to use packages for which they have no access. This flaw may lead to a loss of confidentiality and/or integrity.
