Successful exploits may allow an attacker to crash the application or execute arbitrary machine code in the context of the affected application.
Reportedly, about 30 undisclosed flaws exist.
Update (October 3, 2006): This BID is being retired because reports indicate that these issues are a hoax. The researchers responsible for disclosing these vulnerabilities have claimed that their original reports were incorrect. A remote denial-of-service vulnerability may possibly affect the browser, but this has not been confirmed. A new BID will be created if subsequent reports confirm the possibility of the potential denial-of-service issue. Please see the references for more information.
