Smartphone wireless chipset vulnerable to DoS attack


Security researcher Andres Blanco from CoreSecurity discovered a serious vulnerability in two Wireless Broadcom chipsets used in Smartphones. Broadcom Corporation, a global innovation leader in semiconductor solutions for wired and wireless communications.

Broadcom BCM4325 and BCM4329 wireless chipsets have been reported to contain an out-of-bounds read error condition that may be exploited to produce a denial-of-service condition. Other Broadcom chips are not affected. The CVE ID given to issue is CVE-2012-2619.

In advisory they reported that this error can be leveraged to denial of service attack, and possibly information disclosure. An attacker can send a RSN (802.11i) information element, which causes the Wi-Fi NIC to stop responding.
Products containing BCM4325 chipsets:
  • Apple iPhone 3GS
  • Apple iPod 2G
  • HTC Touch Pro 2
  • HTC Droid Incredible
  • Samsung Spica
  • Acer Liquid
  • Motorola Devour
  • Ford Edge (yes, it's a car)
Products containing BCM4329 chipsets:
  • Apple iPhone 4
  • Apple iPhone 4 Verizon
  • Apple iPod 3G
  • Apple iPad Wi-Fi
  • Apple iPad 3G
  • Apple iPad 2
  • Apple Tv 2G
  • Motorola Xoom
  • Motorola Droid X2
  • Motorola Atrix

  • Samsung Galaxy S 4G
  • Samsung Nexus S
  • Samsung Stratosphere
  • Samsung Fascinate
  • HTC Nexus One
  • HTC Evo 4G

  • HTC Droid Incredible 2
  • LG Revolution
  • Sony Ericsson Xperia Play
  • Pantech Breakout
  • Nokia Lumina 800
  • Kyocera Echo
  • Asus Transformer Prime
  • Malata ZPad
The DoS issue does not in any way compromise the security of users data. Broadcom has a patch available that addresses the issue and makes devices that include the BCM4325 and BCM4329 immune to a potential attack. The Proof of Concept Code and technical details are available at Advisory.
