Adobe patches Flash against zero-day vulnerabilities

No sooner do I write that Firefox is blocking Adobe Flash because of the critical vulnerabilities that are being publicly exploited, than Adobe releases a security update to Flash addressing the zero-day flaws.

Well done Adobe!

(Whatever you think of Adobe Flash, you have to admire the company’s speedy response to the vulnerabilities. Perhaps describing them as “saviour of the universe” is going a bit too far though…)

Unfortunately, at the time of writing, Adobe’s security advisory about the vulnerabilities has not been updated to explain that Flash version resolves the issues – but security journalist Mathew Schwartz told me on Twitter he had received direct confirmation from Adobe.

Of course, all that we need now is for people to update to the latest version of Flash or remove the software from their computer completely.

If you are one of those who will opt for updating Flash rather than kicking it out, then you may be reliant on Flash’s built-in auto updater.

You would normally hope that auto-updating software would be a reasonable route, but unfortunately – in my experience – I have found Adobe’s updater often takes days to notice that a patch is available. So I would suggest more direct action.

The most recent version of Flash is always available from the Flash download page.

Flash update

If you are not sure which version of Adobe Flash you are running on your computer, visit this Adobe webpage which will tell you. Remember, it’s version or later that you are after.

But I would also recommend going further than just updating Adobe Flash.

Consider enabling Click-to-Play, one of the best ways to protect yourself against criminals exploiting vulnerabilities in Adobe’s software.

    What a run-around. I got rid of it altogether and am not going to re-install it only to have some talking head tell me tomorrow to get rid of it. Bunch of jokers.

    It's amazing how one piece of software can be so badly written.
