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"
