Cisco IOS Malformed BGP Packet Causes Reload - Cisco Systems

medium Nessus Plugin ID 48975

Language:

Synopsis

The remote device is missing a vendor-supplied security patch

Description

A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by default, and must be configured in order to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet.
Cisco has made free software available to address this problem.

Solution

Apply the relevant patch referenced in Cisco Security Advisory cisco-sa-20040616-bgp.
