Time to update your Adobe Flash Player, right now: Adobe has issued new patches, the second this month, to fix critical security errors in Flash for Windows, Mac and Linux. This patch is being released outside of Adobe's usual security update cycle, since the previous patch didn't quite fix the problem — or, rather, since hackers were able to quickly develop new ways to work around the patch.
Sophos' Naked Security blog referred to this latest security patch update as a “booster dose” for the previous one. Sophos also went so far as to advise its readers to “Try uninstalling Flash to see if you can live without it. As this incident reveals, Flash is popular with crooks, who put plenty of effort into working out how to exploit it.”
But if you keep Flash installed, try changing your browser settings to require the “click-to-play” or “Ask-to-activate” option, which requires your permission every time before Flash runs on your computer.
And definitely check to make sure you get this patch, although most Adobe users have Flash set to update automatically.
