The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to cause a denial of service (crash) and possibly conduct other unauthorized activities via applet tags in HTML that bypass Java class restrictions (such as private constructors) by providing the class name in the code parameter, aka "Incomplete Java Object Instantiation Vulnerability."

Stack-based buffer overflow in the Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to cause a denial of service via a long class name through (1) Class.forName or (2) ClassLoader.loadClass.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to read and modify the contents of the Clipboard via an applet that accesses the (1) ClipBoardGetText and (2) ClipBoardSetText methods of the INativeServices class.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to read arbitrary local files and network shares via an applet tag with a codebase set to a "file://%00" (null character) URL.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to read restricted process memory, cause a denial of service (crash), and possibly execute arbitrary code via the getNativeServices function, which creates an instance of the com.ms.awt.peer.INativeServices (INativeServices) class, whose methods do not verify the memory addresses that are passed as parameters.

The Microsoft Java implementation, as used in Internet Explorer, provides a public load0() method for the CabCracker class (com.ms.vm.loader.CabCracker), which allows remote attackers to bypass the security checks that are performed by the load() method.

The Microsoft Java implementation, as used in Internet Explorer, allows remote attackers to determine the current directory of the Internet Explorer process via the getAbsolutePath() method in a File() call.

A certain class that supports XML (Extensible Markup Language) in Microsoft Virtual Machine (VM) 5.0.3805 and earlier, probably com.ms.osp.ospmrshl, exposes certain unsafe methods, which allows remote attackers to execute unsafe code via a Java applet, aka "Inappropriate Methods Exposed in XML Support Classes."

Java Database Connectivity (JDBC) classes in Microsoft Virtual Machine (VM) up to and including 5.0.3805 allow remote attackers to load and execute DLLs (dynamic link libraries) via a Java applet that calls the constructor for com.ms.jdbc.odbc.JdbcOdbc with the desired DLL terminated by a null string, aka "DLL Execution via JDBC Classes."

Microsoft Virtual Machine (VM) up to and including build 5.0.3805 allows remote attackers to cause a denial of service (crash) in Internet Explorer via invalid handle data in a Java applet, aka "Handle Validation Flaw."
