Apple has issued security patches to answer four security vulnerabilities in Safari, and has blocked the outdated versions of Adobe Flash Player from running in its browser.
The four security flaws fixed were similar to those that were patched a few days before in iOS 5.1.1 for the iPhone, iPad and iPod Touch. All the vulnerabilities were termed as bugs in WebKit, the open-source rendering engine that powers Safari as well as Google Chrome.
In addition to this, Safari 5.1.7, which runs on OS X 10.6 and OS X 10.7 – Snow Leopard and Lion, respectively – as well as on Windows XP, Windows Vista and Windows 7, was released. An update for Lion that included a bit older version of the browser was also unveiled. Lion users must download and install both updates to push Safari to version 5.1.7.
Along with the four security patches, Apple also stopped Adobe Flash Player from running on Safari if the plug-in was older than version 10.1.102.64, which was released in November 2010.
