-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Symantec Vulnerability Research http://www.symantec.com/research Security Advisory Advisory ID: SYMSA-2007-007 Advisory Title: Palm OS Treo Smartphone Denial of Service Authors: J.R. Wikes Release Date: 20-08-2007 Application: N/A Platforms: Palm Treo 650, 680, 700p & 755p Smartphones Severity: Remotely exploitable / Denial of Service Vendor status: Verified by vendor CVE Number: CVE-2007-4213 [Requested] Reference: http://www.securityfocus.com/bid/25074 Overview: Treo Smartphones running the Palm OS are vulnerable to a remote Denial of Service attack while connected to data networks allowing inbound ICMP traffic. It is possible for an attacker to launch this attack from the Internet by sending specially crafted ICMP requests at the targeted phone's assigned IP address. Details: Sending continuous ICMP echo requests with a packet size of 1470 bytes to the Smartphone's assigned IP address will invoke one (or more) of the following conditions on the device: latency, lockup, forced soft reset, or disconnection from the data network. It is also possible to achieve the same effects with a lower packet size by increasing the interval at which the echo requests are sent to the device Vendor Response: The Symantec issue outlined is an architectural limitation and we will continue monitoring it closely. However, we have not seen any cases where Palm products have been affected. Recommendation: In the interim of a fix being released by the Vendor to address this vulnerability, service providers should implement network filtering controls to restrict inbound ICMP requests to these devices. Common Vulnerabilities and Exposures (CVE) Information: The Common Vulnerabilities and Exposures (CVE) project has assigned the following names to these issues. These are candidates for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems.
