Software giant Adobe is urging Flash users to download a software patch after the discovery of flaw that could be exploited by hackers.
Adobe Flash is a plug-in used by browsers such as Internet Explorer and Google Chrome to play video content. It runs in the background of your computer, so there’s a high chance you are using it without realising.
What has happened?
Security website FireEye discovered hackers were targeting vulnerability in Adobe Flash Player called CVE-2015-3113.
Writing on the company’s blog Erica Eng and Dan Caselden said malicious emails were being sent that “included links to compromised web servers that served either benign content or a malicious Adobe Flash Player file that exploits CVE-2015-3113.”
FireEye informed Adobe of its discovery and Adobe released a software patch.
In a statement Adobe said the patch “addresses a critical vulnerability (CVE-2015-3113) that could potentially allow an attacker to take control of the affected system.
“Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks. Systems running Internet Explorer for Windows 7 and below, as well as Firefox on Windows XP, are known targets. “
Who is affected?
Adobe has classified the issue as ‘Priority 1’ - the highest risk.
PCs with Windows, Mac and Linux are affected running the following versions of Flash Player
- Adobe Flash Player 22.214.171.124 and earlier versions for Windows and MacintosH
- Adobe Flash Player Extended Support Release version 126.96.36.1992 and earlier 13.x versions for Windows and Macintosh
- Adobe Flash Player 188.8.131.526 and earlier 11.x versions for Linux
What do I need to do?
To update Flash and close the loophole to hackers, take the following steps:
1: Visit www.adobe.com/software/flash/about/ to find out which version you are running. You need to be on version 184.108.40.206.
2: If your software is out of date go to https://get.adobe.com/flashplayer/ and install the update. Make sure you deselect any ‘Optional offers’ that appear.
3: Repeat one and two for each browser you are using. Adobe Flash Player installed with Google Chrome and Internet Explorer on Windows 8.x should update automatically.
4: Alternatively if you use Internet Explorer, click the Start menu and enter Windows Update in the search box and let your computer search for updates.
