New Default: Mozilla Temporarily Disables Flash In Firefox
Trailrunner7 writes with news that "Mozilla has taken the unusual step of disabling by default all versions of Flash in Firefox." Two flaws that came to light from the recent document dump from Hacking Team could be used by an attacker to gain remote code execution. From Threatpost's article:
One of the flaws is in Action Script 3 while the other is in the BitMapData component of Flash. Exploits for these vulnerabilities were found in the data taken from HackingTeam in the attack disclosed last week. An exploit for one of the Flash vulnerabilities, the one in ActionScript 3, has been integrated into the Angler exploit kit already and there's a module for it in the Metasploit Framework, as well.
Reader Mickeycaskill adds a link to TechWeek Europe's article, which says these are the 37th and 38th flaws found in Flash so far this month, and that the development "is a blow for Flash after Alex Stamos, Facebook's new chief security officer, urged Adobe to set an 'end of life' date for the much-maligned software."
We need Flash because it is easy to block. You can remove a huge chunk of Web obnoxiousness by simply disabling/uninstalling Flash while not breaking the rest of the website. With HTML5, this won't be as straight-forward process.

Arch Linux master race!
Mozilla did block the then-latest version of Flash Player, 18.0.0.203, last night. Adobe released version 18.0.0.209 early today, which fixes this vulnerability and which Mozilla is not blocking. They didn't really block "all versions," they just blocked versions less than or equal to known vulnerable versions, which at that time happened to also include the then-latest version. Let's stop using misleading phrasing that will make people think they blocked any past, current, or hypothetical future version of the plugin.
