Attention Mac owners. If you use Apple's default Safari Internet browser, it's time to update your software. The new update deals with some serious security flaws that could put your computer at risk.
The first fix deals with a memory corruption issue that could allow for remote code execution. Remotely executing code lets hackers run and download any kind of programs onto your computer like malware, ransomware and keyloggers.
The second issue involves a security problem that could give websites access to files on your computer.
Without the same-origin policy, one web page could read cookies (e.g. login cookies) set by another website, or steal private content (e.g. bank balances) displayed in another page or, in the most extreme case, read data from your local files.
You can check which version of Safari you're running by opening the program and clicking the Safari menu option at the top of the page. Then, click About Safari to see your version.
Safari goes to version 8.0.6 on OS X Yosemite (10.10), version 7.1.6 on Mavericks (10.9), and Safari 6.2.6 on Mountain Lion (10.8).
To install updates to your Safari browser, just click the Apple menu at the top of your computer screen and select "App Store... ." When the App Store opens, click the Updates button at the top of the page.
This section will tell you if there are any updates available. To find out more about these updates, click the More button in the row labeled "Software Update."
If you see an available update for Safari, just click the Update button next to it to download the latest version of the browser.
