Foundstone Security Briefings: Cisco IPv4 Remote Denial of Service Vulnerability Date: Today, Thursday, July 17, 2003 Time: 5:30 PM Eastern, 2:30 PM Pacific Date: Tomorrow, Friday, July 18, 2003 Time: 11:00 AM Eastern, 8:00 AM Pacific You're invited to a Special Web Seminar today covering this critical vulnerability. If you cannot attend today's briefing please see instructions below to register for a follow up Web Seminar tomorrow. Cisco today announced a serious vulnerability for all Cisco devices that implement and are configured to process Internet Protocol version 4 (IPv4) packets. Foundstone Labs, first to respond to this serious risk, is offering this Security Briefing as part of a coordinated effort designed to protect current customers and other organizations. This vulnerability should be considered extremely critical due to the impact and ease-of-exploitation. Devices are vulnerable to a Denial of Service (DoS) attack and although no known exploit has been yet identified, a complex purposely malicious sequence of IPv4 packets targeted to a vulnerable Cisco switch or router can cause the processing interface to stop processing traffic. This vulnerability can be executed by remote unauthenticated users with mere knowledge of at least one interface IP address.
