Synopsis

A flaw in Apache 2.0 could allow a remote attacker to cause a Denial of Service.

Background

The Apache HTTP Server is one of the most popular web servers on the Internet.

Description

Chintan Trivedi discovered a vulnerability in Apache httpd 2.0 that is caused by improper enforcing of the field length limit in the header-parsing code.

Impact

By sending a large amount of specially-crafted HTTP GET requests a remote attacker could cause a Denial of Service of the targeted system.

Workaround

There is no known workaround at this time.
