Lynx Malformed HTML Tags DoS

Medium Nessus Network Monitor Plugin ID 2581

Synopsis

The remote host is vulnerable to a Denial of Service (DoS) attack.

Description

The remote host is using Lynx as a web browser. The version used is vulnerable to a remote attack wherein malformed HTML can cause Lynx to go into an infinite loop. An attacker exploiting this flaw would need to be able to convince a user to browse to a malicious website. Upon a successful attack, Lynx would take up many resources on the client machine, possibly causing a crash in either Lynx or the operating system.

Solution
