Critical error in the method of processing SMS messages in Windows Phone 7

According to WinRumors, a critical vulnerability has been found in the Windows Phone 7 operating system that allows sending a specially generated SMS message to block Hab messages on the device. The error also occurs if a similar message comes from social networks, for example, Facebook.
Also, if a contact has been placed as a tile on the main screen and a “malicious” message comes from that contact, then access to all device functions can be completely blocked.
