Flash-Based Vulnerability Lingers On Many Websites, Three Years Later

itwbennett writes: The vulnerability known as CVE-2011-2461 was unusual because fixing it didn't just require the Adobe Flex Software Development Kit (SDK) to be updated, but also patching all the individual Flash applications (SWF files) that had been created with vulnerable versions of the SDK. The company released a tool that allowed developers to easily fix existing SWF files, but many of them didn't. Last year, Web application security engineers Luca Carettoni from LinkedIn and Mauro Gentile from Minded Security came across the old flaw while investigating Flash-based techniques for bypassing the Same-Origin Policy (SOP) mechanism found in browsers. They found SWF files that were still vulnerable on Google, Yahoo, Salesforce, Adobe, Yandex, Qiwi and many other sites. After notifying the affected websites, they presented their findings last week at the Troopers 2015 security conference in Germany.

Talk about not dogfooding.

disable flash!

there are very few reasons to keep flash installed/enabled. if you must have it, use flashblock but chances are you can just disable/remove it completely. if some site still uses flash to play video, leave a complaint in the comments. those that haven't switched to html5 yet will do so soon enough.

if you still have java plugin installed, you better have a good reason because no (sane) sites use that shit.
