What is CVE-2001-0863?

A vulnerability in Cisco 12000 routers operating on IOS 12.0 affects line cards based on Engine 2. This flaw exists due to improper handling of the 'fragment' keyword in compiled Access Control Lists (ACLs). When exploited, it allows remote attackers to send a flood of fragmented packets to the router, triggering a denial of service condition. As a result, legitimate network traffic may be disrupted, affecting the overall availability of network resources.
