Synopsis
========

Multiple vulnerabilities have been discovered in lighttpd.

Background
==========

lighttpd is a lightweight high-performance web server.

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

    -------------------------------------------------------------------
     Package               /   Vulnerable   /               Unaffected
    -------------------------------------------------------------------
  1  www-servers/lighttpd      < 1.4.18-r2                >= 1.4.18-r2

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

lighttpd contains a calculation error when allocating the global file
descriptor array (CVE-2008-0983). Furthermore, it sends the source of a
CGI script instead of returning a 500 error (Internal Server Error)
when the fork() system call fails (CVE-2008-1111).

Impact
======

A remote attacker could exploit these vulnerabilities to cause a Denial
of Service or gain the source of a CGI script.

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-1.4.18-r2"
