Description:
Marc Schoenefeld has discovered a vulnerability in Sun Java JRE (Java Runtime Environment), which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to missing restrictions on temporary file creation. This can be exploited by a malicious applet to create large files in the temporary folder via e.g. the "Font.createFont()" method.
Successful exploitation causes a vulnerable system to run out of disk space.
The vulnerability has been confirmed in JDK 5.0 Update 6 and has also been reported in SDK 1.4.2_11 on the Microsoft Windows platform.
Solution:
Remove files created by malicious applets in the temporary folder "%temp%" when running out of disk space after an attack.
