Synopsis
========
Multiple vulnerabilities in lighttpd may lead to information disclosure
or a Denial of Service.
Background
==========
lighttpd is a lightweight high-performance web server.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-servers/lighttpd < 1.4.20 >= 1.4.20
Description
===========
Multiple vulnerabilities have been reported in lighttpd:
* Qhy reported a memory leak in the http_request_parse() function in
request.c (CVE-2008-4298).
* Gaetan Bisson reported that URIs are not decoded before applying
url.redirect and url.rewrite rules (CVE-2008-4359).
* Anders1 reported that mod_userdir performs case-sensitive
comparisons on filename components in configuration options, which is
insufficient when case-insensitive filesystems are used
(CVE-2008-4360).
Impact
======
A remote attacker could exploit these vulnerabilities to cause a Denial
of Service, to bypass intended access restrictions, to obtain sensitive
information, or to possibly modify data.
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-1.4.20"
