With Watch OS 1.0.1 Apple has released the first update for its watch. While it doesn’t include any flashy new features you should definitely make sure to install the patch as soon as possible, since it includes fixes for several critical security issues.
One of them is the well known FREAK bug, the SSL/TSL vulnerability which was disclosed in March. The vulnerability can allow hackers to perform a Man in the Middle (MITM) attack on traffic routed between a device that uses the affected version of OpenSSL and many websites, by downgrading the encryption to an easy to crack 512 bits (64KB).
Other than that the update includes fixes for vulnerabilities that could lead to arbitrary code execution, disclose information, cause a denial of service, redirect user traffic to arbitrary hosts, and bypass network filters.
According to Macworld Watch OS 1.0.1 also improves your Apple Watch’s performance, adds seven new languages, and support for new emoji.
To install the new Watch OS just do the following: Open your Apple Watch app on your iPhone and go to My Watch > General > Software Update. Make sure that the watch is within range of the iPhone and connected to a charger. It should also be at least 50 percent charged.
