The iPhone 4 and a slew of older devices from Apple, Samsung, HTC, and other manufacturers are vulnerable to attacks that can make it impossible to send or receive data over Wi-Fi networks, a security researcher said.
Proof-of-concept code published online makes it trivial for a moderately skilled hacker to disable older iPhones, HTC Droid Incredible 2s, Motorola Droid X2s, and at least two-dozen other devices, including Edge model cars manufactured by Ford. The Denial-of-Service vulnerability stems from an input-validation error in the firmware of two wireless chips sold by Broadcom: the BCM4325 and the BCM4329. The US Computer Emergency Readiness Team has also issued an advisory warning of the vulnerability.
"The only requirement to exploit the vulnerability is to have a wireless card that supports [the] raw inject of 802.11 frames," Andrés Blanco one of the researchers from Core Security who discovered the vulnerability, told Ars. "The Backtrack Linux distribution has almost everything you need to execute the POC provided in the advisory."
