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 lt; 1.4.18-r2 gt;= 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 "gt;=www-servers/lighttpd-1.4.18-r2"
