Apple Once Again Blocks Older Versions of Adobe Flash Player Due to Vulnerability

by

Last week Adobe issued a security advisory for Flash Player, indicating that version 21.0.0.242 and earlier had a critical vulnerability that could potentially cause a crash and allow an attacker to take control of the infected system. Adobe issued a fix a couple days later.

Apple today published a support document explaining that users with out-of-date versions of the Adobe Flash Player plug-ins will see a "Blocked plug-in," "Flash Security Alert," or "Flash out-of-date" message when attempting to view Flash content in Safari.

Plug-ins like Adobe Flash Player have long been an issue for Apple, requiring forced updates and security fixes to patch vulnerabilities. When vulnerabilities arise, Apple has been consistent in blocking older versions of the web plug-ins. Apple is looking to reduce the risk of potential issues with macOS Sierra, in which Safari will deactivate Flash Player and other plug-ins by default in an effort to push the more modern HTML5.

To continue using Flash, users must download the latest Adobe Flash Player update from Adobe's website.

Oh, for God's sake, everyone uninstall Flash now. Use Google Chrome for the small amount of noob sites that use it.

Steve Job's thoughts on Flash, dated April 2010. Six years on, still valid:
