Sun Java Runtime Environment Font Object Assertion Failure

Denial Of Service Vulnerability

The Sun Java Runtime Environment Font object is reportedly vulnerable to an assertion failure denial of service vulnerability. This issue is due to a failure of the process to handle exceptional conditions when processing font objects.

This issue is reported to affect Java Runtime Environment versions 1.4.1 through 1.4.2; it is likely however that other versions are also affected. This issue will crash Internet browsers running an affected Java plug-in as well.

This issue may be exploited by an attacker to cause a vulnerable application, as well as all processes spawned from the application, to crash, denying service to legitimate users. Due to the scope of the crash, data loss may occur.
