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"
