Sun Java Plug-In 1.4 through 1.4.202 allows remote attackers to repeatedly access the floppy drive via the createXmlDocument method in the org.apache.crimson.tree.XmlDocument class, which violates the Java security model.

The org.apache.xalan.processor.XSLProcessorVersion class in Java Plug-in 1.4.201 allows signed and unsigned applets to share variables, which violates the Java security model and could allow remote attackers to read or write data belonging to a signed applet.

Java Plugin 1.4 for JRE 1.3 executes signed applets even if the certificate is expired, which could allow remote attackers to conduct unauthorized activities via an applet that has been signed by an expired certificate.
