Thought you were safe opening e-mail attachments on your cell phone? Guess again, friends. CNET News reports that a vulnerability has been discovered in garden-variety Motorola RAZR handsets that could allow a hacker to send a corrupt JPEG image, via Multimedia Messaging Service (MMS), that could be leveraged to run malicious code on the phone. You'd have to accept the image for download before that could happen, however.

"Although the possibility of this vulnerability occurring is very remote," a company statement said, Motorola has now fixed the vulnerability in all new releases of the RAZR and urges people with older devices to download the latest software from its Web site, according to the report.
