Mobile Safari in the iOS 7 has a vulnerability (CVE-2014-4377) that can let attackers remotely gain access to your iOS device. A device with the flaw can be compromised if the user visits a website that has either been specially designed or hijacked to attack the vulnerability.
The vulnerability was later fixed in the iOS 8 release. However, iPhone, iPad and iTouch devices which have not been (or in some cases, cannot be) upgraded to the latest operating system version remain vulnerable to attacks against this flaw.
