Detail

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

apache2-mpm-perchild apache2-mpm-prefork apache2-mpm-threadpool apache2-mpm-worker

The problem can be corrected by upgrading the affected package to version 2.0.50-12ubuntu4.1. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Chintan Trivedi discovered a Denial of Service vulnerability in apache2. The field length limit was not enforced for certain malicious requests. This could allow a remote attacker who is able to send large amounts of data to a server to cause HTTP server instances to consume proportional amounts of memory, which can render the service unavailable.
