Synopsis
========

A processing error in lighttpd might result in a Denial of Service
condition.

Background
==========

lighttpd is a lightweight high-performance web server.

Affected packages
=================

    -------------------------------------------------------------------
     Package               /   Vulnerable   /               Unaffected
    -------------------------------------------------------------------
  1  www-servers/lighttpd      < 1.4.25-r1                >= 1.4.25-r1

Description
===========

Li Ming reported that lighttpd does not properly process packets that
are sent overly slow.

Impact
======

A remote attacker might send specially crafted packets to a server
running lighttpd, possibly resulting in a Denial of Service condition
via host memory exhaustion.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All lighttpd users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
    ">=www-servers/lighttpd-1.4.25-r1"
