iOS 8.2 has been released last night for iPhone, iPad and iPod Touch, the Apple company providing us with the update with the idea of solving extremely many operational problems, including some vulnerabilities. One of the most important allowed iPhones to be restarted through a simple SMS sent by a hacker, now the problem is impossible to exploit in terminals that have installed this update. Separated, iOS 8.2 blocked another vulnerability used in TaiG jailbreak iOS 8, so that Chinese hackers will have to use other exploits in future possible jailbreak solutions.
A null pointer dereference issue existed in CoreTelephony's handling of Class 0 SMS messages. This issue was addressed through improved message validation. An issue existed in the developer disk mounting logic which resulted in invalid disk image folders not being deleted. This was addressed through improved error handling.
Apple usually details all the security issues fixed in an iOS update and now has a this page in this sense, the most important vulnerabilities that have been resolved are listed there. Having said that, if you have not yet installed iOS 8.2 on your own iDevices, it would be good to do so because you will solve many performance problems and you will have the new Apple Watch application available.
