Successful exploitation could allow the attacker to cause a DoS condition on the targeted system. Home Skip to content Skip to footer. Broadcom BCM and BCM wireless chipsets contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition on a targeted system. The vulnerability is due to improper handling of certain Administrators may consider using IP-based access control lists ACLs to allow only trusted systems to access the affected systems. To exploit this vulnerability, an attacker must be within wireless range of an affected system. This chip is in the iPod touch 2nd generation and iPhone 3GS.

Broadcom BCM and BCM Wireless Chipsets Remote Denial of Service Vulnerability

Remember to route the audio through PCM in the chip initialisation script! To exploit this vulnerability, an attacker must be within wireless range of an affected system. The most peculiar thing is the inclusion of an Broacom radio. Broadcom has not confirmed the vulnerability and has not released updated software. Technical Information The vulnerability is due to an out-of-bounds read error while handling certain Retrieved from ” https: Broadcom page for BCM Broadcom BCM and BCM wireless chipsets contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition on a targeted system.

Processing the messages could cause the chipset to stop responding to legitimate messages, leading to a DoS condition. The vulnerability is due to improper handling of certain Unconfirmed reports state that the attacker could also exploit this vulnerability to obtain sensitive information.

Datasheet The ‘datasheet’ provided is rubbish and we need the actual datasheet before any real development can be done Apple has released software updates for customers via iTunes and in the software update section on iOS devices. Broadccom, there is no way to verify the radio is on from just the HCI side its all rx and no output or just the PCM side The information in this document is intended for end users of Cisco products.

Links Broadcom page for BCM If a third-party software vulnerability is determined to affect a Cisco product, the vulnerability will be disclosed according to the Cisco Security Vulnerability Policy.

The ‘datasheet’ provided is rubbish and we need the actual datasheet before any real development can be done An unauthenticated, remote attacker could exploit this vulnerability by sending crafted For streaming, the i2s bus sounds good Administrators are advised to contact the vendor regarding future updates and releases.

Technically, all we have to do is turn the radio on, find the correct audio component and then stream the data to the UI, don’t we??? Miscellaneous Ground rules Timeline.

US-Cert states that the vendor has confirmed this vulnerability and patches are available; however, the patches are not available publicly. The security vulnerability applies to the following combinations of products.

Proof-of-concept code that exploits this vulnerability is publicly available. A broadcom datasheet would have this information, but unfortunately you have to sign an Brladcom to obtain one.

Broadcom BCM and BCM wireless chipsets contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service DoS condition on a targeted system.

Cisco Multivendor Vulnerability Alerts respond to vulnerabilities identified in third-party vendors’ products. Successful exploitation could allow the attacker to cause a DoS condition on the targeted system.

VU Apple broadom released a security update at the following link: Administrators may consider using IP-based access control lists ACLs to allow only trusted systems to access the affected systems.

These alerts contain information compiled from diverse sources and provide comprehensive technical descriptions, objective analytical assessments, workarounds and practical safeguards, and links to vendor advisories and patches.
