Apple has released an iPhone OS 3.0.1 patch addressing the vulnerability in its SMS application introduced at the Black Hat Security conference yesterday.

The patch is now available and is 230 megabytes.

It addresses the vulnerability issue through improved error handling, according to the company. The update is only available through iTunes, and will not appear in computer’s Software Update application, or in the Apple Downloads site.

Cybersecurity researchers Charles Miller had reported the bug to Apple on June and he first  discussed the vulnerability on the first week of July  in an event at a Singapore security conference.

Miller and a fellow cybersecurity researcher Collin Mulliner  discussed the vulnerability once again yesterday  during a Black Hat presentation, showing how hackers could infect phones virally through SMS.

Apple credited Charlie Miller and Collin for reporting the issue.
