Apple has released a minor software update for iPhone, patching a security flaw revealed just yesterday.

Security researchers Charlie Miller and Collin Mulliner on Thursday revealed a memory corruption bug that could be easily exploited by crashing an iPhone with a series of invisible text messages, which would then enable a hacker to hijack the device. From thereon, a hacker could control all the functions on the iPhone — most alarmingly, he could send more text messages to hijack even more iPhones.
