Adobe Flash 11.3 for Firefox now runs in a sandbox! Yay. It’s not super strong, it should be virtually identical in nature to Chrome’s NPAPI sandbox, which Vupen broke out of twice. Still, this moves the cost of Flash exploitation far above what it used to be.
Chrome users will also be pleased to know that the PPAPI plugin has moved to 11.3 and it is really stable. I’m running it full time and youtube and google music run flawlessly.
So it’s a good day for security. You can expect Flash exploits in the wild to wither away because all three major browsers now sandbox it. Where will hackers go? Well… either we’ll start seeing more sophisticated attacks on the Windows system (kernel exploits, yada yada) or we’ll start seeing attacks on other plugins like… Java.
My advice… either EMET Java or uninstall it. It’s just gonna get worse for that plugin.
