iPhone vulnerability: A new vulnerability in the iPhone or iOS devices in basic has come to light. Reverse engineer Carl Schou has shared that he and his not-for-profit group Secret Club discovered not too long ago that public WiFi networks that include the percentage symbol in their names have the capacity to disable the WiFi on iPhones and other iOS devices when these devices are in the variety. This indicates that the iOS device would not be capable to use any features connected to WiFi, and the problem may possibly not necessarily be gone even when the user has reset the network settings.

They discovered that if an iPhone got in touch with a network that had %p%s%s%s%s%n as its SSID name, it triggered a bug in the networking stack of the iPhone, disabling its WiFi and rendering technique networking features like AirDrop unusable.
Many are seeking for attainable explanations for this, and 9to5 Mac has presented a probably one: that the % symbol followed by a character is a widespread syntax in the programming language used to format variables in an output string. It is attainable that the SSID name is getting sent by the WiFi subsystem with no any adjustments to an internal library exactly where string formatting is getting carried out, and due to this, it could be an arbitrary memory create and buffer overflow, top to memory corruption. The approach could for that reason possibly be killed by the iOS watchdog, disabling the whole WiFi feature.
It is not but recognized irrespective of whether Cupertino is working on a answer to repair this problem, but as per 9to5 Mac, the problem may possibly be avoided by not connecting an iOS device to a network containing % symbols in their name.
