CVE-2003-0896: High severity Sun Java Runtime Environment (JRE) vulnerability

Published Oct 25, 2003
·
Updated

The loadClass method of the sun.applet.AppletClassLoader class in the Java Virtual Machine (JVM) in Sun SDK and JRE 1.4.103 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.
