Overview

Vendor Notes:

Many systems run a service called the browser will act as though viewing a file of infinite length. This has caused a modem connection to drop using MSIE and slowed a Linux system using lynx to a crawl due to exhaustion of memory.

Category:

DoS: An exploit whose purpose is to deny somebody the use of the service: namely to crash or hang a program or the entire system. Examples of DoS attacks include flooding the victim with more traffic than can be handled; flooding a service (like IRC) with more events than it can handle bomb; crashing a TCP/IP stack by sending corrupt packets; crashing a service by interacting with it in an unexpected way; or hanging a system by causing it to go into an infinite loop. For example, the Ping of Death exploit crashed machines by sending illegally fragmented packets at a victim. A common word for DoS is ""nuke"", which was first popularized by the WinNuke program.
