Apple Blocks Old Versions Of Adobe Flash On OS X Safari
After the recent discovery of yet another critical vulnerability in Adobe Flash, although it was fixed last week, Apple has activated a Web plug-in blocking capability for OS X Safari browser to protect Mac users from what Adobe describes as “limited, targeted attacks.” Even if they are limited and targeted at specific type of individuals or systems, it’s better to be safe than sorry, right?
Apple posted a support document to its website on Monday saying Flash versions older than 126.96.36.199, or 188.8.131.52 on older machines, are now actively restricted from running on OS X. The precautionary measure is instituted to protect users unaware of the situation.
Adobe confirmed the presence of this vulnerability in their product last week and said malicious users were conducting real world attacks to crash and possibly even gain control of affected systems. A fix for the issue was launched on Friday.
As noted by Apple, Mac users running insecure Flash software will see the message “Blocked plug-in,” “Flash Security Alert,” or “Flash out-of-date.” Clicking the alert link takes users to Adobe’s Flash installer page where the latest version of the plug-in can be downloaded and installed.
Apple is known be proactive in shielding unsuspecting customers from Flash vulnerabilities (which have been quite a lot in recent years). The company activated its plug-in blocker last summer to protect against a flaw that allowed attackers to collect browser data, and most recently did the same in April.
