Detail

Synopsis

Multiple vulnerabilities in lighttpd may lead to information disclosure or a Denial of Service.

Background

lighttpd is a lightweight high-performance web server.

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"

Title: DSA-1645 lighttpd -- various
Description: Several local/remote vulnerabilities have been discovered in lighttpd, a fast webserver with minimal memory footprint. The Common Vulnerabilities and Exposures project identifies the following problems: A memory leak in the http_request_parse function could be used by remote attackers to cause lighttpd to consume memory, and cause a denial of service attack. Inconsistant handling of URL patterns could lead to the disclosure of resources a server administrator did not anticipate when using rewritten URLs. Upon filesystems which don't handle case-insensitive paths differently it might be possible that unanticipated resources could be made available by mod_userdir.
