Multiple unspecified vulnerabilities in Sun Java JDK and JRE 5.0 Update 5 and earlier allow remote attackers to bypass Java sandbox security and obtain privileges via unspecified vectors involving the reflection APIs, aka the "fifth, sixth, and seventh issues."

The loadClass method of the sun.applet.AppletClassLoader class in the Java Virtual Machine (JVM) in Sun SDK and JRE 1.4.1_03 and earlier allows remote attackers to bypass sandbox restrictions and execute arbitrary code via a loaded class name that contains "/" (slash) instead of "." (dot) characters, which bypasses a call to the Security Manager's checkPackageAccess method.
