TITLE

Yamaha RT Series Router IP Header Resolution Denial of Service Vulnerability

DESCRIPTION

Yamaha RTX, RT, SRT, RTV, RTW, and RTA series routers with firmware 6.x through 10.x, and NEC IP38X series routers with firmware 6.x through 10.x, do not properly handle IP header options, which allows remote attackers to cause a denial of service (device reboot) via a crafted option that triggers access to an invalid memory location. Multiple routers provided by Yamaha contain a denial-of-service vulnerability. Multiple routers provided by Yamaha contain a denial-of-service (DoS) vulnerability due to an issue in processing IP packets. Yuji Ukai of Fourteenforty Research Institute, Inc. reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.A remote attacker may cause a denial-of-service (DoS). The Yamaha RT Series Router is a high speed broadband router device. A security vulnerability exists in the Yamaha RT series router when parsing IP packets, allowing an attacker to perform a denial of service attack on the device. Successful exploits will cause the device to crash, denying service to legitimate users. ---------------------------------------------------------------------- Q1 Factsheets released: http://secunia.com/resources/factsheets/2011_vendor/ ---------------------------------------------------------------------- TITLE: Yamaha RT Series Routers IP Header Parsing Denial of Service Vulnerability SECUNIA ADVISORY ID: SA44087 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/44087/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=44087 RELEASE DATE: 2011-04-12 DISCUSS ADVISORY: http://secunia.com/advisories/44087/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/44087/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=44087 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: A vulnerability has been reported in the Yamaha RT Series Routers, which can be exploited by malicious people to cause a DoS (Denial of Service).
