The Java Database Connectivity (JDBC) classes of Microsoft's Java virtual machine (VM) contain functions that do not properly validate parameters. A malicious Java applet can exploit this vulnerability to crash programs on the client system.
Microsoft's Java VM is installed on Windows 98, NT, 2000, and XP. It is used by Internet Explorer and Outlook Express to execute Java applets.
The VM includes classes that provide JDBC functionality to Java applets. Certain functions in these classes do not properly validate their parameters. By specifying invalid parameter handles, a malicious applet can cause programs running the VM (such as Internet Explorer) to crash. It may also be possible to execute arbitrary code on the client system, though this has not been demonstrated or proven.
A malicious applet can cause the VM and dependent programs such as Internet Explorer to crash.
