Firefox Javascript Vulnerability Was A Joke

Instead of a dramatically vulnerable JavaScript engine in the Firefox browser, the speakers at ToorCon were presenting code that one admitted will not enable remote code execution.

Mozilla's engineers will continue to investigate potential issues with the way Firefox handles JavaScript, even though Mischa Spiegelmock has now admitted their presentation at ToorCon was a hoax.
Spiegelmock and Andrew Wbeelsoi made the buzzworthy claim that Firefox was critically vulnerable to attack.
Its JavaScript virtual machine could be exploited in a way that would allow someone to run arbitrary code remotely on a person's machine.
Window Snyder, chief security officer for Mozilla, wrote that initial testing of the code presented at the conference could cause a denial of service problem, sometimes crashing the browser.
She later followed up with another post based on an exchange with Spiegelmock, who wrote that he and Wbeelsoi were just trying "to be humorous":
As part of our talk we mentioned that there was a previously known Firefox vulnerability that could result in a stack overflow ending up in remote code execution.
However, the code we presented did not in fact do this, and I personally have not gotten it to result in code execution, nor do I know of anyone who has.
I have not succeeded in making this code do anything more than cause a crash and eat up system resources, and I certainly haven't used it to take over anyone else's computer and execute arbitrary code.
I do not have 30 undisclosed Firefox vulnerabilities, nor did I ever make this claim. I have no undisclosed Firefox vulnerabilities.
The person who was speaking with me made this claim, and I honestly have no idea if he has them or not.
I apologize to everyone involved, and I hope I have made everything as clear as possible.
Wbeelsoi claimed to have 30 undisclosed flaws he discovered in Firefox, and laughed off a request to submit them to Mozilla's Bug Bounty program.
That claim now looks less likely given Spiegelmock's statement.
