A couple of days ago, Apple decided to do a little in-house cleaning with its browser - by releasing a new version of its Safari, with the intended purpose to patch four security vulnerabilities.
Also, Apple blocked out of date versions of Flash Player "that do not include the latest security updates" from running on Safari. This decision is similar to last month's move to stop a Java plug-in to run automatically.
This strategy, however, goes both ways. Recently, Oracle decided to bypass Apple and bring the Java SE 7 update directly to Mac users. Apple might be forced to take a closer look at the security features of all its software and OS after the recent massive Trojan attack.
Safari itself was discovered to have a security flaw that put iOS users at risk a couple of months ago. All four security vulnerabilities are the ones fixed with the latest iOS update for iPhone, iPad and iPod - iOS 5.1.1.
Safari 5.1.7 runs on OS X 10.6 and 10.7, also known as Snow Leopard and Lion, and on Windows XP, Vista and Windows 7.
