According to developer Andrei Neculaesei, some applications on iPhone (Tel exploits) make unknowing calls to users, which can lead to high charges.
Some apps, including Facebook Messenger, gmail and Google+, recognize one phone number as a link and iPhone can make a call to that number.
This can cause it large charges at account of the user when calls are made to high-cost numbers that have been deliberately placed within the applications by malicious digital criminals.
For this particular "vulnerability" are responsible developers of applications, not iOS, however Apple Lossless Audio CODEC (ALAC), will allocate one Update for these “tel exploitsSo that users are informed before each call is made.
